CHAPTER – II INTRODUCTION OF THE PROJECT/ BACKGROUND INFORMATION

2.1 Identification of the Project & Project Proponent 2.1.1 Project Government of Jharkhand vide letter No. MSTC/RNC/Department of Mines and Geology/5/Jharkhand/17‐18/21987 dated 05.01.2018 issued a Notice for grant of Mining Lease (ML) for Bhangaon Iron ore Block over an area of 111.0 Ha in village Bhangaon, Saranda forest Division, Dist West Singhbhum , Jharkhand for a resource size of 38.25 Million Tonnes. The mine has been planned to excavate 2.0 MTPA of Iron Oreas per the present mining plan. In pursuant to the Mines and Minerals (Development and Regulation) Amendment Act, 2015 and The Mineral (Auction) Rules, 2015, Govt. of Jharkhand issued the notice inviting tender dated January5, 2018 for commencement of the auction process to grant the mining lease in respect of Bhangaon Iron ore block located in village Bhangaon, Saranda Forest Division, District West Singhbhum, Jharkhand. Thee‐auction process was conducted inaccordance with the tender document and the Mineral Auction Rule, 2015 for said mineral block and M/s SOUTH WEST MINING LIMITED (SWML) was declared as the Preferred Bidde runder Rule9(4)(b)(iii) of the Mineral (Auction) Rules 2015. SWML has deposited a sum of INR2,12,38,860/‐(Rupees Two crores Twelve Lakh Thirty Eight Thousand Eight Hundred and Sixtyonly) through GRN 1802532732 as payment of first installment ie, 10% of upfront payment on 7thAugust, 2018. Subsequently, a letter of intent (LoI)was issued to M/s SOUTH WEST MINING LIMITED (SWML) for grant of mining lease of Bhangaon Iron ore Block comprising of 111.0 Ha within the limiting co‐ordinates of the ‘Precise Area Map’ provided by the Govt. of Jharkhand as attached in Annexure‐1.

2.1.2 Project Proponent South West Mining Ltd (SWML) is a Public Limited Company having its Registered office at JSW Mining Office Vidyanagar, Talur Cross, Toranagallu, Bellary 583275, Karnataka. The company was incorporated in the name of “Jindal Fertilizers Ltd” on 8th October, 1996. Subsequently the name of the company was changed to “South West Mining Ltd.” with effect from 25th June 2001. The company is primarily

Page 6 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

engaged in carrying out the mining activities with its well‐equipped resources for Iron ore, Lignite, Limestone etc.

2.2 Brief description of nature of the Project Bhangaon Iron Ore Mine is situated in tehsil of in Saranda Forest Division with an area of 111.00 Ha. of forest land. SWML proposes to carry out opencast method of mining for2.0 MTPA of Iron Ore from Bhangaon Iron Ore Mine by fully mechanized method using shovel dumper combination. The excavated ROM ore is proposed to be processed in the crushing and screening plants to obtain the lump and fine ore as product mix. The total life of mine is envisaged as 14 years. The total manpower required for the project will be about 206 people. Water requirement is 186 KLD for drinking and other purposes. This will be met for initial two years by making weir on a perennial nallah flowing by side of lease area and later by water pumped from the rain water harvesting pit. Moreover DTH drilling is proposed during the first year of working within the non mineralized area which will be used as water drill holes based on the availability of water during drilling.

2.3 Need for the Project & its Importance to the Country & Region Iron ore remains the most crucial driving force for the steel industry in and the industry’s growth so far can largely be attributed to the domestic availability of low cost and high quality iron ore. The steel industry today directly contributes to 2% of India’s Gross Domestic Product (GDP) and its weightage in official Index of Industrial Production (IIP) is 6.2%. Globally also over the last two decades India has become world’s 3rdlargest producer of crude steel preceded by China and Japan. It is further expected that the steel production will grow at a much faster pace in the country and therefore the requirement of iron ore for the domestic iron and steel industry will be quite substantial in coming years. Development of the mine will create employment and source of income generation in the region. There will be development in secondary & tertiary sectors as well.

Page 7 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

2.4 Demand & Supply Gap The per capita consumption of steel in India in FY 2017‐18 was 69 Kg against the world average of 214.5 Kg. The National Steel Policy 2017 has projected anannual demand of 437 MT of Iron Ore for steel industry to meet the per capita steel output of 158 Kg by FY 2030‐31, an increase of 89 Kg above the present per capita levels. So there is a big gap in demand and supply.

2.5 Import vs Indigenous Production India does not need to import iron ore but for last two years import has taken place due to court imposed restrictions in key producing states like Karnataka, Odisha, Goa, etc. for curbing illegal mining. Production of iron ore from this mine will partially meet the demand for iron ore &reduce need for import.

2.6 Export Possibility Iron Ore excavated from the proposed mine will be transported to the domestic Steel Plants. Hence no export possibility exists

2.7 Domestic / Export Market The iron ore produced from this mine will be largely consumed by steel sector in domestic market reducing the need for import.

2.8 Employment Generation (Direct and Indirect) due to the Project There will be direct employment of 206 people involved in iron ore mining. There will be also employment opportunity in Secondary & Tertiary Sector.

3.3 Details of Alternative Sites The block has been vested by Govt. of Jharkhand. The lease area of 111.00Ha.has sufficient iron ore reserve to continue mining operation for 14 years and as such no alternative site was considered.

3.4 Size or Magnitude of Operation This is a new mine planned to produce 2.00 MTPAof Iron Ore capacity by opencast method with a proposed lease area of 111.00Ha. Physiography & Drainage:‐ The area represents a very hilly and rugged topography. The highest point is 863m above mean sea level while the lowest altitude is 587 m above mean sea level. The highest altitude comprises of Banded Iron ore formation while the lower altitude bearing area comprises shale, laterite and soil of reddish & chocolate colour. Bhangaon iron ore block area has no perennial streams flowing down the slope. There is no major source of perennial water in the area. However a number of Nalas pass through the nearby area. One perennial nalais situated in the western direction of the block area, around 1.25Km away. This is locally named as Koinagarand is flowing towards north. The buffer zone of 10 Km area has shown dentritic pattern of drainage system and is mainly drained by two rivers viz. Karo and which flow from south to north. Karo and Koina are the principal drainage channels of the area. Karoriver flows on the eastern side and Koina River flows on the western side of Kiriburu – hill range. On eastern part of block area, there are other seasonal nallas such as Pacherinala, Rogarnalla, Champuanala, Jhikarianala, Panposhnala and Balagodanala. All these nallas join Kororiver on eastern side. Similarly on western side there are other seasonal nallas like Sankoja, Gagirathi, Meghahatu, Sasangdih, Pardih, Rang‐Ring etc. which join Koinariver on western side

Regional Geology Geologically, the terrain around the area forms part of the oldest meta‐sedimentary and metavolcanic formations of the Chhotanagpur plateau, situated on the Budaburu and Baichindigiburu hill ranges, considered as homotaxial with the Dharwars in the Indian geological column. It is believed that the iron‐rich formations of the Bonai‐ Keonjhar range form part of the Iron Ore Series.

Page 10 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

In a generally accepted opinion, iron ore bearing Banded Iron Formations (BIFs) occur between the overlying shales, phyllites, sandstones, lavas, ash and tuff beds, and the basal sandstone conglomerates, occurring at the base of iron ore group which unconformably overlays the older metamorphics. Profuse volcanic activity in the form of tuff beds,has been noted within the BIF. The Iron Ore Group of rocks outcrops around the Singhbhum granite body. Precambrian Singhbhum cratonic nucleus of eastern India falls in the states of Jharkhand & Orissa and preserves imprints of several geological cycles spanning from the early Archaean to at least early Neoproterozoic (Saha 1994). The ancient cratonic block, known as Singhbhum Craton or as Singhbhum‐Orissa Iron Ore Craton remained a major attraction to the geoscientists and miners for the immense potential of this belt in terms of major mineral deposits such as copper, uranium, iron, manganese, chromite, and limestone amongst others.

Local Geology The Iron Ore deposits of Bhangaon area is a part of famous horse shoe (U) shaped iron ore basin which is known as Banaisynclinorium. This basin, occurring at western fringe of Singhbhum Craton located in parts of Jharkhand and Odisha, is the main repository of iron ore deposits of Eastern India which is particularly associated with the Banded Haematite Quartzite/ Jasper of which they represent enriched portion. This Banded Haematite Quartzite crops out and is arranged as ridges in the form of a narrow horse shoe shape with closed end to the south in Keonjhar and Bonai in Odisha and with sides about 13Km apart open to the North‐East in Singhbhum in Jharkhand. The ridge forming the western side of the horse shoe is known as Iron‐ Ore Range, which is persistent for some 48Kms. There are four important litho units identified in the Bhangaon area, viz.Banded Heamatite Quartzite (BHQ), Metasedimentary beds of iron ore, Banded Heamatite Jasper (BHJ) and Banded Magnetite Quartzite. The BIF consists of BHQ, BHJ, BMQ& iron ore which are naturally confirmable and present as regular thick beds. Banded Heamatite Quartzites are the basement litho units of BIF below which greenish argillaceous shale rock is present. The exposures of this particular unit are found on the top of the series of the hills within the area. The Iron Ore mineralization of this area is mainly in the form of heamatite which occurs within the BIF on the ridge tops. The Iron ore deposits occurring in the area has a general strike NNE‐SSW with south‐ westerly dipping. The dip amount varies between 65º to 75º. However,

Page 11 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

the strike of the Iron Ore bodies differs at places due to locally developed structural disturbances. The Iron Ore deposit (Heamatite) is massive, hard and dark brown to steel grey in colour, having widely spaced joints. Flaky and friable ore with brown to grey in colour is also available. The dark blue fine grained very rich type of powdery Iron Ore (Blue Dust) also occurs in association with flaky ore. Generally, at lower level Sub‐grade ores are also available. The Iron Ore mineralization in the Bhangoan area has been divided into following types a) Lateritic Ore b) Hard and massive Ore c) Thickly Laminated Ore d) Thinly Laminated Ore e) Biscuity Ore f) Powdery Ore

Lateritic ore is formed due to chemical weathering of Iron ore exposed in the upper surface in the area. Massive ore has been formed by complete local enrichment of the ferruginous rock. Soft or Porous shaly ore has been formed by leaching out of silica from BHQ/BHJ. Powdery Ore occurs where there has been almost complete removal of silica from BHQ without any cementation of the remaining Haematite grains which are left as loose powder. The geological plan of Bhangaon Iron Ore Mine has been attached as Plate‐IV.

3.5 Project Description with Process Details Method of Mining:‐ Being a hill‐top deposit, Bhangaon iron ore block is amenable to open cast mining by fully mechanized method with a fairly high degree of mechanization. Open cast mining is ideal for the Bhangaon Iron Ore Block especially, in view of low OB/waste thickness and high iron ore thickness. Due to the gentle slope of the Bhangaon iron ore Block, the conventional horizontal bench method of mining has to be adopted for this deposit. Mining fronts are planned to advance almost north – South parallel to the surface contours & strike length of the ore. This will allow mining of full profile of the iron ore thickness with longer strike thereby enabling blending from different top & bottom sections.

Page 12 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

In order to take into account the interburden pockets of ferruginous clay intersection in between the ore zone, special precautions need to be taken to avoid dilution of the ore. The mine will be worked by fully mechanized opencast mining method. The sequence of mining operation is given below:‐ Step – A removal of Overburden / Interburden  For mining of iron ore, seam needs to be exposed by removing overburden / interburden.  For removal of overburden / interburden blast holes will be drilled using drills.  Blast holes will be filled with explosives and blasting will be carried out to break the mass of Overburden.  Blasted material will be loaded into dumpers by shovel.  Overburden will be stored over area specified for dumps. Step – B For mining of iron ore, activities will be carried out in following sequence :  Drilling blast holes in iron ore deposit.  Filling drill holes with explosives.  Blasting  Loading of blasted mass of iron ore to dumpers by shovels.  Transport of ROM iron ore to mobile crushing plant. Step – C  ROM iron ore will be crushed in primary crushers to maximum size of 200 mm.  After crushing, the crushed material will go to secondary cone type crusher.  The crushed material from secondary crusher will be screened through various types of screen sizes to make the product size +5 mm to +20mm and +10 mm to 40 mm and fines of ‐10mm to ‐5mm. Step ‐ D  Iron Ore will be carried to loading point at Railway Siding through dumpers.

Page 13 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

Sequence and Direction of Advance Considering the above factors, from the hill top around 860m mining operation will be started by slicing / contour mining to the down ward followed by the hill slope in the southern part of the lease area by developed haul road of 10m width of gradient 1:16. Development will be continued up to the third year towards northern direction followed by the strike of the terrain & almost 700m long face will be developed & 2.0 Mt ROM will be produced from this developed faces by average two or three benches further in every year. In this area the thickness of over burden is very low; this OB & sub‐grade iron ore will be produced in the top benches. This produced sub‐grade will be stacked on the non mineralized area as shown on the plan. Waste will be dumped in the non mineralized area by terracing in the hill slope of average 10m height of every terrace. Toe wall or parapet of 2m width & 1.5m height of loose boulders / concrete will be constructed in the toe of the dump for stability of the dump. Garland drain channel will be constructed by cutting of 2m width & 1.5m depth at the toe of the dump & connected to a number of check dams & settling ponds for sedimentation etc.

Blasting Although proposed area is very far away from any population, precaution will be taken to minimize nuisance caused by blasting. All necessary safety precaution will be taken in accordance with the Explosive Act. Precaution will also be taken as per permission obtained under MMR 1961 106(2) by Director of Mines Safety for deep hole drilling & Blasting and usage of heavy earth moving machinery. Vibration: In order to minimize vibration, the following precautions will be taken: 1. Blast holes will be initiated by non‐electric DTH delay detonators. 2. Care will be taken to ensure that effective burden will not be excessive and the face will be kept sufficiently long. The burden will be kept at 4m & spacing will be 4.5m 3. Number of blast holes per delay will be kept as low as possible. 4. The depth of the hole will be normally 6 m, which includes about 1 meter of sub grade drilling. The diameter of the hole is kept at 150 mm (6 inch). 5. Adoption of two row blasting and V pattern of firing. 6. The firing of maximum possible no. of blast holes towards free face. 7. Use of delay detonators between the holes and rows of blasting. Noise: The following steps will be taken to minimize pollution by noise. 1. Blasting will be well designed & blasted periodically rather than couple of hastily unplanned blast daily. All the explosive and the raydet (NONEL) is put within the blast hole& detonating fuse is not used for trunk line.

Page 23 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

2. Blasting will be so planned to minimize boulders, so that secondary blasting will be reduced. 3. Green belt with trees of varying height will be developed around the quarry to absorb the blast noise & reduce noise.

Method of Blasting In this mine, deep hole will be in practice. Holes will be made in hard formation by Wagon drill having diameter from 150 mm up to depth 6 m. Burden and spacing will be maintained 4m x 4.5m. Depending upon the compactness of the strata/formation yield 108 cum or 356 tonnesof explosives will be used and the powder factor will be approx 5 tonnes/Kg.

Blast‐Patterns can be extrapolated for required number of rows. These are straight‐ line pattern & staggered pattern. Suitability of blast pattern will be established through actual field trials & accordingly adopted. The blast holes are proposed to be charged with SMS by the loading Truck. Suitable stemming material such as drill hole cutting may be used or possibilities may be explored for using sized material to increase the blast‐efficiency. The broad blasting parameters of the primary blasting operations proposed to be carried out at this area are given in the table 3.7

4.7 Climate Data from Secondary Sources The climate of this district is characterized by a hot summer, well distributed rainfall during the southwest monsoon season and mild humid post monsoon season. The year may be divided into four seasons. The cold season commences from December to February. The hot season from March to first week of June and the monsoon season is from June to September. October and November constitute the post monsoon season or transitional period between southwest monsoon and winter seasons.

RAINFALL Records of rainfall in the district are available for eleven raingauge stations for period ranging from 10 to 45 years. The details of the rainfall at these stations and for the district as a whole are given in Tables 1 and 2. The average annual rainfall in the district is 1288.2 mm. During the southwest monsoon months June to September the district receives about 82% of the annual normal rainfall. August is the rainiest month with an average rainfall of 327.0 mm. The variation in the rainfall from year to year is large. In the fifty year period 1951 to 2000, the highest annual rainfall amounting to 144% of the normal occurred in 1956, while the lowest annual rainfall which was 62% of the normal occurred in 2000. In the same fifty year period there were 8 years in which the annual rainfall in the district was less than 80% of the normal. However, none of them were consecutive years. It is seen from Table 2 that the rainfall was between 1001 mm and 1500 mm in 28 years out of 45. On an average there are 65 rainy days (i.e. days with rainfall of 2.5 mm or more) in a year in the district. This number varies from 57 at Manjhari to 71 at Majhgaon. The heaviest rainfall recorded in 24 hours at any station in the district was 401.1 mm at Manjhari on 21 June 1977.

Page 33 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

TEMPERATURE There is only one observatory in the district located at Chaibasa. The records of temperatures and other climatological parameters prevailing at this station may be taken to be broadly representative of the whole district. Temperatures begin to decrease progressively from November. December and January is the coldest part of the year with the mean maximum temperature at abour 25.8°C and the mean minimum temperature at 11.5°C. In association with cold waves, which affect the district in winter months in the wake of western disturbances which move across north India, the minimum temperature may go down to about 4°C on individual days. Temperatures begin to rise steadily after mid February till first week of June. May and early part of June before the onset of southwest monsoon constitute the hottest part of the year. In May the mean maximum temperature is at 39.3°C and the mean minimum temperature is at 25.7°C. During this period, maximum temperature may reach about 45°C on some days. The maximum temperature decreases and weather becomes appreciably cool with the advance of the southwest monsoon by about the second week of June and continues to be so throughout the season. From November temperatures begin to decrease. The highest maximum temperature and the lowest minimum temperature ever recorded at Chaibasa (observatory) were 46.7°C on 22 May 1948 and 4.4°C on 19 January 1934 respectively.

HUMIDITY The summer months March to May are driest part of the year when the relative humidity in morning is about 50% to 60% and about 30% to 40% in the afternoon. The air is humid in southwest monsoon season, when the relative humidity is about 80%. During the rest of the year the air is generally dry and mild humid with the relative humidity at about 50% to 70%.

CLOUDINESS In the winter and early part of summer skies are generally clear or lightly clouded. However, on some days in the winter in the wake of western disturbances skies are heavily clouded to overcast. The cloudiness increases from April to southwest monsoon months, skies are heavily clouded or overcast. Cloudiness decreases from October.

WINDS Winds are generally light with slight increase in force in the latter part of summer and southwest monsoon season. In summer and southwest monsoon season winds are predominantly southwester1y. In the rest of the year winds are calm.

SPECIAL WEATHER PHENOMENA

Depressions originating in the Bay of Bengal during the southwest monsoon affect the weather of the district and its neighbourhood during their northwesterly or

Page 34 M/s Crystal Consultants PRE-FEASIBILITY REPORT FOR BHANGAON IRON ORE OPENCAST PROJECT

wester1y movement after crossing the coast. This causes gusty winds and widespread heavy rain. Thunderstorms occur throughout the year except in December. Its frequency is more in latter part of summer and southwest monsoon season. Tables 3, 4 and 5 give normals of temperature and relative humidity, mean wind speed and special weather phenomena respectively for Chaibasa observatory.

5.4 Assessment of Infrastructure Demand (Physical &Social),Amenities &Facilities Power Supply The power line passes nearby lease area and the existing power network will be utilized with facility of stand by generators.

Mobile Crushing & Screening Plant Initially only crushing and screening of ore will be done at mine site. ROM grade ore as such cannot be sent directly to the plant. ROM ore will be subjected to crushing and dry screening. The crusher will be equipped with dust suppression system. With this sizing and dry screening, there will be enhancement in the grade of the ore by a minimum of 0.5%. The dispatch grade of ore will be maintained as per the requirement of the buyers. The +55% Fe will be upgraded by wet beneficiation outside the mining lease boundary to achieve the required grade for steel plant. Considering 300 working days in a year and three working shifts, the size of the mobile crushing & screening plant should be 2,000,000 tonnes ÷ 300 days ÷ 18 hours per day (effective) = 370 tonnes. So, one 500 tph mobile crushing & screening plant is proposed for installation in first year itself at a place shown on the development plans.
