2.2 COMMUNICATION

District headquarter Sundergarh, on State Highway-10 (Sambalpur to Rourkela), is at a distance of about 46 km. from the blocks. The Sundergarh (Orissa) – Raigarh (Chattisgarh) all weather road passes through the blocks. The blocks are also connected by black top road with two important towns of Orissa namely Rourkela at 145 km and Jharsuguda at 75 km. The blocks come under Himgir Tahsil and Balinga police station in the district of Sundergarh, Orissa. The blocks are about 6 km. south west of Basundhara (West) OCP and are connected by part metallic road. Nearest rail head is Himgir on Mumbai-Howrah Broad Gauge of South Eastern Railway at a distance of about 35 km from the blocks. Jharsuguda railway station on Jharsuguda-Sambalpur-Bhubaneswar rail line of East Cost Railway is at distance of about 75 km. The nearest port at Bay of Bengal is Paradip and situated at a distance of about 600 km from the block. The Jharsuguda airport is the nearest airport from the block.

2.3 PHYSIOGRAPHY & DRAINAGE The block under reference is represented by paddy fields, small hillocks and forests. Major part of the block is however, covered by paddy fields. Basundhara river flowing west to east in the northern boundary of the block separates the blocks from Chaturdhara/Basundhara blocks and Chattanjhor nala flowing south to north in the eastern boundary of the block separates the block from Kulda block. One of the tributaries Barjhor nala flows from south to north towards the middle of the block and many other small nala cris cross within the block. Besides these, there are some small ponds and dug wells available within the block and used for irrigation and drinking purposes. The general topography of the block is undulating and is used for agricultural purpose and some patches of barren lands are also featuring in the block. The general altitude of the block is varying from 260 metres to 311 metres. The lowest elevation is about 260 metres near borehole CMHG-45 along the Basundhara river within Siarmal and Siarmal Extn. block and highest elevation is about 311 metre and is located near the south-western corner near boreholes

Banapatra block. 2.4 CLIMATE The area experiences a sub-tropical warm temperature. About 70% of rainfall occurs during rainy season i.e. June to Sept. As per IMD data of Jharuguda 2016 the highest 24 hourly rainfall occurs in the month of August 63.20 mm. The temperature varies from 7.4oC to 45.3oC for the year 2016. The predominant wind direction is SW to NE.

3.0 MARKETING AND JUSTIFICATION The consumers of MCL are linked to the company and not to any specific coalfield. The actual supply from any coalfield of MCL will depend upon the production and transport logistics. Under the above circumstances coalfield wise demand has been assessed based on the production share of these two coal field which is as below: Projected coal demand on MCL from Ib-valley coalfield. (Fig. in Mt) Sl. No Particulars 2021-22 2026-27

1 Total Demand on MCL 244.83 274.134 2 Projected coal demand on Ib-valley 97.93 120.56 coalfield 3 Coal Availability 73.82 85.32 Gap (-)24.11 (-)35.24

As per the above estimate, there is gap between demand and availability of MCL by from Ib-valley coalfield alone. Further new coal linkages have been given to MCL for which MCL has already issued LOA. The proposed project will meet the coal demand from the coalfield, especially to the new consumers and reduce the gap between demand and availability. The coal seams in both the blocks under consideration for the project (Siarmal & Siarmal Extn. and Banapatra) are thick and occur at shallow depth. The entire net geological coal reserves of 1866.83 Mt has high quarriable potentiality. Considering the coal demand on MCL and quarriable potential of the blocks, formulation of the present opencast mine for rated capacity of 50.0 Mty is justified.

4.1 BLOCK BOUNDARY

The details of the boundary of the Siarmal and Siarmal Extension block are given below:

North : Northern boundary of the block is marked by east west trending Basundhara river.

South : Southern boundary is marked with arbitrary boundary of Barren Measures formation.

East : Eastern boundary is limited by Kulda block along Basundhara river, then followed by Chattanjhor nala.

West : Western boundary of the block is limited by Eastern boundary of Western Extension of Siarmal (Banapatra) block.

The limits of Banapatra block are as given below:

East : Western boundary of Siarmal & Siarmal Extn. block.

West : Eastern boundary of Rampia and Dip side of Rampia block.

North : Southern boundary of Chaturdhara & Basundhara West blocks

South : Northern boundary of Prajapara block

4.2 STATUS OF EXPLORATION

The blocks under consideration (Siarmal & Siarmal Extn. and Banapatra) have been explored in detail and geological reports are available for both the blocks, in Siarmal & Siarmal Extn. and Banapatra blocks combined, a total of 503 borehoes (by CMPDI & GSI) have been drilled covering an area of 14.67 sq.km with a borehole density of 34 BH/sq.km.

Job No.706124 Pre-feasibility Report, Page - 4

CMPDI

4.3 GEOLOGICAL STRUCTURE Mostly soil, alluvium or weathered mantle cover the area under investigation. As such, the geological features of the block are interpreted mainly on sub-surface data. Though Talchir and Karharbari Formations have been encountered in boreholes drilled in nearby blocks, but they do not incrop or outcrop within the block. However, Barakar Formation outcrops at places in nala tract/cutting.

Since these two blocks from the structural continuity along with the adjoining blocks, the correlation, seam nomenclature, structural trend etc., have been maintained from the adjacent blocks i.e. Basundhara, Garjanbahal, Kulda, Basundhara East and West blocks.

The faults extending from the above adjoining blocks have been considered while making structural interpretation of the blocks. The nomenclatures of some of the faults have been given afresh following certain pattern. The nomenclatures of these faults are based on either encountering boreholes or level difference in floor of the seams. DIP AND STRIKE

The strike of the strata has shown northwest – southeast trend with minor variation towards northern part. The strata dips 3° – 4° towards southwest. The same has increased to about 10° in the northern part with dip direction remaining towards south to southwest.

FAULTS

In total 28 number of faults with throw varying from 0 to 120 m have been deciphered in Siarmal & Siarmal Extn. and Banapatra blocks combined. Out of seven faults interpreted in Siarmal & Siarmal Extn. block, six faults extends to Banapatra block and hence common in both the blocks. In Siarmal and Siarmal Extn. block, seven numbers of faults viz. F1-F1 to F7-F7 with varying amounts of throw and direction have been interpreted in the area under consideration. Eighteen boreholes have directly intersected the faults. The fault F1-F1 is continuing from adjacent Basundhara block with a throw of about 20 m. Most of the faults trend east to west.

Job No.706124 Pre-feasibility Report, Page - 5

CMPDI

In Banapatra block, twenty seven no. of faults with throw varying from 0 to 120 m have been interpreted mostly in the northern part of the block based on either direct evidence in boreholes or through level difference of seam floors.

4.4 COAL SEAMS In Siarmal & Siarmal Extension and Banapatra block total 16 nos. of corelatable coal horizons/seams have been identified. In the Karharbari Formation Ib seam occurs in three splits. Barakar Formation contains seams Rampur and Lajkura in number of splits. Altogether, 13 nos. of seams / split seams are reported in Barakar Formation in this block. Among these, seam Rampur-I, II, III, IV, Lajkura-I, IIB, IIT1 and Lajkura-IV are the most potential thick coal horizons in this block.

5.0 MINE BOUNDARY, RESERVES & LIFE

The proposed pit considers most of the area of the combined block, barriers will be left towards north and east due to presence of Basundhara river and Chhatajhor nala respectively.

In view of conservation of coal, mine floor considered is the floor of any of the three sections of Ib seam which is found to be the lowermost workable seam having thickness of more than 1m within the block. In the area where all the sections of Ib seams area less than 1m quarry floor will be limited to the bottommost section of Rampur seam.

Within the mine boundaries detailed above, extractable coal quantity is estimated as 1547.82 Mt with corresponding overburden of 2269.69 Mcum. The life of the project is 38 years.

5.1 SURFACE BOUNDARIES

North : After leaving a sufficient surface barrier from the Basundhara river. This surface barrier will accommodate embankment against the river after considering HFL of that area, a transport road and conveyor passage. Embankment width will vary as per surface elevation in that area. West : 15m from common block boundary between Banapatra and Rampia block. This space is required for drain, one road and fencing. Towards northwest corner 60m barrier is kept for nala diversion along the common boundary. South : Floor of Lajkura-I seam is limited upto southern geological block boundary, the surface boundary has been arrived further south with a quarry slope angle of around 370 with horizontal towards south.

6.0 MINING TECHNOLOGY Different technologies like shovel-dumper mining, dragline mining, bucket wheel excavator mining and surface miner-payloader-truck mining are available for opencast mining. Sometimes combination of several methods of mining are adopted to suit particular type of mining situations.

Job No.706124 Pre-feasibility Report, Page - 9

CMPDI

Shovel-dumper system is very flexible and also offers convenient mining operations to deal with sudden occurrences of unworkable or poor quality patches and change of floor position due to repeated faulting and varying seam gradient and thickness. It also offers flexibility for easy transition to any other technology or equipment configuration. The technology is well known and advantageous to get skilled manpower. So shovel-dumper mining method is adopted for overburden removal and partial coal extraction.

Surface-miner excavation is still limited to winning coal only. This method of mining by deploying outsourcing agencies has become very popular in Talcher & Ib valley coalfield. There are many advantages in this technology, of avoiding drilling, blasting, crushing of coal and related environmental hazards, improvement in grade of ROM coal by removing thin bands, clean surface for transport etc. Ideally, surface miners require working space of about 400 m length and about 50 m width for its optimum use. The high-wall angle required is comparatively flatter to shovel- dumper system. This bench geometry makes overall working angle flatter which will generate more overburden compared to shovel-dumper system if the seams are thin with thick intermediate parting. But as seams Lajkura-IV, IIT1,IIB,I and Rampur- IV,III,I are thick seams with number of bands, surface miner will be introduced in these seams. Other thin seams and lower seams with thick intermediate parting. But as seams Lajkura-IV, IIT1, IIB, I and Rampur-IV, III, I are thick seams with number of bands, surface miner will be introduced in these seams. Other thin seams and lower seams with thick intermediate partings will be worked by either surface miner or shovel-dumper system depending on geological and geotechnical conditions. As the seam gradient is relatively flat (around 30 to 40), coal and the parting will be worked by parallel slicing method (working along seam floor) whereas top overburden and thick parting between Rampur and Lajkura seam will be removed by level slicing method.

10.0 DUMPING Minimum depth of the lowest quarriable seam in north-east corner of the quarry-1 is around 115m, so a long access trench is necessary to reach the quarry floor. It has been designed to develop the quarry initially with extraction of upper seams and simultaneously deepening the quarry in the lower seams to maintain high rate of production, in this process access trench of the quarry will be developed to touch the bottommost quarry floor, so there will be no internal dumping during this period upto year9. After year9 as the mining in quarry-1 is extended towards both west and south some quantity of backfilling can be started, but the volume of void generation in the quarry will be much less compared to the volume of overburden generated due to following reasons.

 Presence of multiple faults and narrow working width between different faults in northern part/ rise side of the quarry requires sufficient advance in overburden benches.  Much void space will be lost with increase in depth due to creation of different dump tiers to maintain overall dump slope of 260.  Western slope cannot be filled upto surface to avoid high quantity of rehandling.  Long access trench/haul road on eastern quarry batter has to be maintained during quarry operation, so this side of the quarry cannot be filled up upto end of mining operation in quarry-1. All these factors will lead to a situation of creation of low void generation.

Dip side of quarry-1 cannot be filled upto surface after completion of its operation due to continuation of coal seam in the dip side block. So lot of void at a high depth towards dipside will be unused, all these factors necessitate requirement of huge external dumping.

There is no non coal bearing area in the block or towards south in dipside, the block is surrounded by Basundhara river and Chattanjhor nala towards north and east respectively, so there is no favourable area for external dumping in close proximity. Only non coal bearing area is available towards north of existing Basundhara west OCP, this area has been already selected for power plant to be set up by Mahanadi Basin Power Corpoartion Ltd which is a subsidiary of MCL. So only the void in Basundhara West OCP can be filled up by some quantity of overburden from Siarmal OCP. But construction of a bridge over Basundhara river is necessary to transport overburden, this bridge should be capable of withstanding load of heavy duty 190t rear dumpers suggested for overburden transport. Construction of this bridge may take long time, considering this fact it is proposed

to dump initial overburden towards dipside of quarry-2 towards south-western side. From year7 to year10 some dumping will also be done into the voids of Basundhara west OCP.

External Dump towards dipside of quarry-2 will accommodate 89.25 Mcum of overburden and external dumping in this area will continue upto 8th year. This dump will have to be rehandled while extending the mine operation towards dipside of the block after 38 years. Exploration in this dipside block should be completed before starting of external dumping. Economic viability of mining operations in the dipside block can be studied only after detailed exploration. From 7th year this same external dump will be extended towards north in the future quarry area of quarry-2 by overburden from quarry-1, around 193.85 Mcum of overburden of quarry -1 from year-7 to year14 will be dumped in mining area of quarry-2, this huge volume of overburden has to be rehandled while working quarry-2 in year29 to year38.

Backfilling in the quarry-1 will be started from year-10, simultaneous backfilling and external dumping will be done upto year18, from year19 there will be no external dumping and total overburden can be backfilled. From year12 to year18 external overburden will be located beyond southern boundary of quarry-1. This dump will have to be rehandled while extending the mine operation towards dipside of the block. Exploration in this dipside block should be completed before starting of external dumping. Economic viability of mining operations in the dipside block can be studied only after detailed exploration. Average height of all the external dumps will be around 82-85 m. care has been taken to accommodate external dump in the notified boundary of MCL.

It is proposed to complete the construction of heavy duty bridge over Basundhara river within year6 so that overburden from the mine can be transported beyond Basundhara river, the available void in Basundhara West OCP can be filled up by the overburden from Siarmal OCP in year7 to year10. Around 77.18 Mcum of overburden can be accommodated in exhausted Basundhara west OCP, some void towards dipside of this mine will not be filled for maintaining water reservoir considering scarcity of water in this area.

Average height of the external dump will be around 82-85 m. Details of external dumping and yearwise dumping schedule and are shown in following tables respectively.

11.0 PUMPING & DRAINAGE The principal drainage in the block is controlled by Basundhara river flowing west to east on the northern side of the block. The Chattanjhor flowing in the eastern boundary of the block controls the local drainage. Chattanjhor maintains base flow even in the summer.

The following considerations have been made for calculating the pumping requirement and selection of pumps: 1.
