Revised Pre-feasibility Report OF Pichri OCP 12 ( Normative Capacity 1.20 MTPA & Peak Capacity 1.50 MTPA) , Limited

Revised Pre-feasibility Report

1.1 Brief Description & History of the Project

Proposed Pichri OCP is located in the eastern part of East Coalfield in of and falls under the jurisdiction of Dhori Area of CCL. A part of the proposed Pichri OCP is in the leasehold area of existing Dhori Khas Project property.

The coal seams occurring in this block have moderate washing characteristics and are suitable for feeding to nearby proposed Dhori Washery.

Pichri OCP is envisaged to produce washery grade-IV coal to meet the demand of medium coking coal. Project Report for Pichri Opencast has been prepared for a nominal target of 1.20 MTPA (1.50 MTPA peak) coal at an estimated capital investment of Rs. 228.90 crores.

Mining activities in Pichri Block were started much before the nationalization. Existing Pichri Mine was taken over from M/s Shivram Singh by BCCL and later on transferred to then CMAL, and now finally to CCL. A number of small quarries had been worked in the incrop region of seam and Karo X/IX/VIII Seam along the south bank of River Damodar. The details of these quarries are not available and presently these quarries are water logged.

Three inclines were also driven by M/s Pichri Company Private Limited from the face of Quarry No.1 for the underground development of Bermo Seam. These inclines were closed on 26.9.1968 due to an underground explosion.

1.4 Location & Communication

Pichri OCP is located in the eastern part of East Bokaro Coalfields in Bokaro District of Jharkhand. The project is bounded between Latitudes (N) 23 0 45’ 00” and 23 0 45’ 50” and Longitudes (E) 86 0 01’ 00” and 86 0 02’ 30”. A part of Pichri Block is under the lease hold of Dhori Khas Colliery.

The block is situated on the Jaina More – – Jarangdih – road joining NH- 2 and NH-23. (30km), (60 Km), (130 Km) and Ranchi 130 (km) are also well connected by road. – – Barakana Loop Line of Eastern Railway is located to the north of the block. Phusro Railway Station is situated at a distance of only 2 km from the block. The nearest Airport connected by daily commercial flights is at Ranchi. Another private airstrip belonging to is at Bokaro Steel City.

1.5 Nature & Size

Pichri OCP is a new mine proposed in Bokaro District of Jharkhand in of Jharkhand. The normative capacity of the project is 1.20 MTPA and peak capacity is 1.50 MTPA. The total land requirement for this project is 151.47 Ha. The life of the project is 20 years.

1.6 Physiography and Drainage

The block is situated on the southern bank of . The general elevation in the block varies from 195 m to 215 m above MSL. In the summer season, Damodar River can be crossed on foot when the water level drips down to about 190 m RL.

Prepared by CMPDI, RI-III, Ranchi Revised Pre-feasibility Report OF Pichri OCP 15 ( Normative Capacity 1.20 MTPA & Peak Capacity 1.50 MTPA) Dhori Area, Central Coalfields Limited

However, in the monsoon season the river covers a part of the block. The HFL is recorded as 205.66m (1976).

Climate

The area enjoys semi extreme type of climate. The day temperature during summer (March-June) rises to around 40 0C and drops to around 10 0C during nights. The day temperature during winter is around 25 0C which comes down to around 5 0C during night. The rainy season (July-October) accounts for 82% of annual precipitation with average rainfall around 1259.6 mm (annually).

2.1 Need for the Project

The quarry was being worked with the help of the equipment diverted from the adjacent mines. However, production from this mine was discontinued from 2002-03 due to mine seepage and uneconomic working condition. In this revised PFR, it is envisaged to produce coal @ 1.20/1.50 MTPA (nominal/ peak) by adding suitable required equipment.

2.2 Justification For The Project

The need for the Project arises out of the following considerations :

To bridge demand and supply gap of coking coal, it is essential either to open new projects or to expand the existing mines where medium coking coal is available for mining. As per the Geological Report on Pichri Block, sufficient coal reserves including coking coal reserves are available for quarrying. Coal seams incrop within the block. A part of surplus manpower present in Dhori Area may be utilized gainfully.

2.3 Present Proposal

The detailed techno-economic study to mine Karo VI/VII, Karo VIII/IX/X, Bermo and Kargali seams has been done. The boundary of the mine has been fixed leaving sufficient surface barrier from Damodar river to accommodate protective embankment and space for mine transportation needs. The strike length of the quarry is limited as the block is surrounded by Damodar river on 3 sides and by state highway on remaining side. Small strike length added to steep dip nature of the seams in the entire block restricts inclusion of Karo III and Karo V seams in the proposed quarry. Inclusion of Karo III and V seams in the proposed quarry will result in coal transportation bottlenecks as well as low recovery of lower seams not considered in this proposal. In the present proposal, the forest land has been excluded.

2.4 Difficulties and Constraints in Mining

• Pichri opencast mine is situated on the south bank of Damodar River. The highest flood level of this river as recorded in 1976 is 205.66m. Many small quarries were opened in the area by private parties during 1960-70. After nationalisation, when quarry no. 3 & 4 were reopened, a protective embankment was made along the river bank by dumping overburden. The embankment did

not prove to be very effective and water percolates through the embankment during rainy season. As a result quarry used to get drowned during monsoon. • 200 Nos of PAF’s to be rehabilitated from 2 Bastis i.e Jamtand Basti and Tungri Coolie Basti of Pichri Village.

Construction of Protective Embankment Construction of protective embankment is a critical activity and a properly designed and constructed protective embankment is needed before planning any major expansion of this mine. Services of any agency with prior experience and technological know-how of design and construction of protective embankment may be taken, if required.

Mining System and system parameters

The mining and geological conditions of the mine are as follows: (a) Multi seam working. (b) Varying gradient of the seams (15 o-20 o). (c) Variable thickness of coal seam and top OB.

Considering the above mining and geological conditions, Shovel-Dumper mining system has been envisaged for working this opencast mine. The gradient of the seams varies from about 15 deg to 20 deg. Considering the steep dip property of the seams in the quarry area, horizontal slicing method of mining has been proposed. The working and non-working benches have been shown in the quarry cross-sections.

The suggested equipment configuration has been dealt separately in this report. Considering geo-mining condition, life of the project and distribution of excavation load over the life of the project, 5.5m 3 Diesel Hydraulic Shovel will be used to extract OB while 3.8m 3 Diesel Hydraulic Shovel will be used to extract coal. Equipment are proposed to be shared between the workloads while minimising the travel distance of shovel.

Coal Winning & O.B. Removal

Geo-technical parameters of the mine

a) Multi bench scenario from the first year of mine operation due to steep dip nature of the deposit (1 in 3) and initial quarry depth (>85m) b) Small strike length (600m along floor for the quarry) resulting in insufficient/inconsistent annual benchwise work load. c) Each shovel to cater more than one bench/horizon requiring frequent marching of shovel. Considering above geo-technical parameters Diesel Hydraulic shovel is proposed as digging equipment for both coal and OB as it provides much needed flexibility of operation in such mines.

Diesel hydraulic shovel with bucket size of 5.5 cum with 60 te dumper have been proposed for OB removal. Diesel hydraulic shovel with bucket size of 3.8 cum with 35 te dumper have been proposed for coal production

Mining Strategy The major part of the Pichri block falls between two regionally extending faults viz. Govindpur Pichri fault and southern boundary fault. The Govindpur Pichri fault is represented by two parallel faults (F1 & F2) with a generalized east west trend and down throwing towards south. These two faults passing through the central region of the block and has a throw varying from 230m to 560m. The Govindpur Pichri fault divides the block in two parts. The area lying north of this fault is free from structural disturbance. Thick Bermo, VIII/IX/X & VI/VII occur at shallow depth in this region. The central part of the block is traversed by a number of faults of throw varying from 0 to 140m. The southern half is highly disturbed. The Pichri opencast has been planned to be worked in the north of Govindpur Pichri fault upto the floor of Karo VI/VII seam.

Prepared by CMPDI, RI-III, Ranchi Revised Pre-feasibility Report OF Pichri OCP 19 ( Normative Capacity 1.20 MTPA & Peak Capacity 1.50 MTPA) Dhori Area, Central Coalfields Limited

The total extractable reserves have been estimated as 18.99 Mtes corresponding to a volume of OBR of 36.54 Mm 3. at an average stripping ratio of 1.92 m 3/te. With this annual rate of production, the life of the mine is estimated as 20 years.

Coal Winning & O.B. Removal

Considering the geo mining characteristics of the mining block, opencast method of mining with shovel-dumper combination is proposed to work.

Prepared by CMPDI, RI-III, Ranchi Revised Pre-feasibility Report OF Pichri OCP 23 ( Normative Capacity 1.20 MTPA & Peak Capacity 1.50 MTPA) Dhori Area, Central Coalfields Limited

The proposed mine is planned for nominal production of 1.20 MTY for a life of 20 years.

2.8 Water Demand

The potable water requirement for the project has been assessed as follows:

(i) Potable Water Demand : 280 m 3/day (ii) Industrial Water Demand : 1175 m3/day

The average rate of mine water pumping has been estimated as 1,920 m 3/day. It is proposed to utilize treated mine water to meet industrial & domestic water demand.

2.9 Water Management

The pumping system of Pichri Open cast project of CCL has been designed to dewater the inflow of water due to precipitation within the active pit limit during the monsoon and non-monsoon season and the ground water discharged from aquifers to enable the mining activity to continue round the year.

The planning of dewatering the mine has been done in such a way that the working faces and haul roads will remain dry as far as possible. The layout of the quarry provides suitable gradient along the quarry floors and the benches to facilitate self drainage of water to the sump at the lowest level of the quarry. The average rate of mine water pumping has been estimated as 1,920 m 3/day.

Water flowing from the check dams would join near by nallah and finally Damodar River.

2.10 Power Supply

Source of Electrical Power Supply :

The proposed Pitchri Opencast project is located in Dhori Area. Dhori Area substation which supplies power to all Dhori group of mines is having an installed capacity of 2 x 10 MVA, 33 / 11 kV. It receives power from adjacent Kargali Regional substation of B & K Area. DVC is the supply agency for Kargali regional substation.

Metering point (common for B&K Area and Dhori Area) is at Kargali. Power is received at check post substation (Dhori) by means of 2 nos. 11 kV OHTL feeders (feeder I & II), each 3.5 km long, connected to the 2 x 10 MVA transformers mentioned above. Another 11 kV feeder (feeder- III) is also connected with the 2 x 10 MVA transformers for feeding power to other load centers of this area. At the check post substation, two nos. 11 kV indoor type switch boards are installed for centralized control of power supply to all the mines / townships of Dhori Area. In order to cater to the power demand of proposed OCP, it is proposed to draw a single circuit 11 kV OHTL (approximately 4.5 km long) from the above mentioned Dhori check post S/S.

Prepared by CMPDI, RI-III, Ranchi Revised Pre-feasibility Report OF Pichri OCP 24 ( Normative Capacity 1.20 MTPA & Peak Capacity 1.50 MTPA) Dhori Area, Central Coalfields Limited

At the project, substation for transforming the incoming 11 kV supply voltage to 6.6 kV would be established for feeding power to all the electrical groups of receivers proposed for this project. Transformer capacity for both the Variants has been kept same in this report.

2.11 Workshop & Store

A new unit workshop has been proposed. This unit workshop is envisaged to cater the need of daily maintenance, schedule maintenance, lubrication, routine inspection, minor repair and replacement of parts/sub-assemblies of HEMM such as- Dumpers, Dozers, Shovels, and Drills etc. Minor repair of assemblies and sub-assemblies of pumps, CHP equipment, electricals etc. deployed in the project will also be performed in this workshop.

Any major repair of equipment and manufacturing of spares on large scale are beyond the scope of this workshop. These works will be carried out in Regional Repair Shop or Central Workshop.

The workshop will have a project store to meet the total requirement of proposed workshop as well as additional requirement of the project. Only day-to-day requirement of spares and consumables will be kept in the workshop store for smooth functioning of workshop

2.12 Coal Handling & Despatch System

The total production of Pichri OCP has been the proposed as 1.20 MTPA. Coal from this mine will be transported to nearby washery or Phusro Railway siding by tipping truck after crushing of ROM coal in the proposed CHP. The average quality of the coal is washery grade-IV.

The coal handling plant shall have facilities for receiving coal from rear discharge dumpers, crushing of coal & conveying in the overhead hoppers for storing and loading in the trucks. The coal handling plant has also been provided with suitable repair, communication and other auxiliary facilities to meet the day to day requirement in the plant operation.

2.14 Civil Construction

The life of this project has been estimated as 20 years. For residential, service and welfare buildings, permanent type of construction has been proposed.
