INTRODUCTION 2.1 Identification of Project and Project Proponent TISCO LIMITED is the Lessee of the proposed Mine. The details are as given below: Name of the applicant TISCO LIMITED Now TATA STEEL LIMITED Name & Address of POA Holder TATA STEEL LIMITED P.O. Jamadoba District - Dhanbad (Jharkhand)- 828112 Number of Leases held by the lessee Lease deed Date 29.11.1983 Name of Mine Damodarpur, Palkiri, Chatatand, Bhojudih, Narkera Sand Mining Project Mineral Sand (Major Mineral) Area (ha) 50.17 Ha Postal Address Tata Steel Limited P.O. Jamadoba District - Dhanbad (Jharkhand)-828112 Period of Lease (Yrs) 31.03.2030 as per MMDR Act 2015, Sec 8(A)(5). Status of Mine It is not in operation since October’2012 2.2 Brief description of the nature of the project It has been proposed to collect approximately 3.5 lakhs tonnes/year. The river-bed material will be replenished during the monsoon season every year. Surface Mining: The mining is confined to collection of sand from the river bed. The operation will be Semi-mechanized with the help of Backhoe Dumper Combination in which the river bed material will be collected in its existing form. Sand Mining will be carried out only upto a depth of 2 m at river bank and in water it could not be measured, excavation machines along with hand tools like shovel, pan, sieve etc. will be used. Mining will be carried out only during the day time. 2.3 Need for the project and its importance to the country and region The river carries with it huge quantity of sediment consisting of stones, gravel and sand during every monsoon. The sediment in the form of river bed material (RBM) deposited in the last many years had changed the shape of the river bed from a valley to a raised land. 2 Because of this, every year during monsoon season, heavy and devastating floods damage large tracts of land lying on both the banks of the river. Tata Steel produces approximately 1.91 million tones coal per annum from five captive underground coal mines in Jharia group of collieries. For this Tata Steel requires approx. 3.0 million tonnes of sand per annum for stowing/backfilling the voids created in underground after extraction of coal from these mines. As these mines are lying under populated area, railway lines, important roads, power transmission lines etc. simultaneous sand stowing (Underground backfilling) is essential for prevention of subsidence and fire during extraction of coal because it may damage these surface. Hence this project is required for collection of sand necessary for underground stowing. The sand to be collected /gathered from these leases along the river will be sent to the underground coal mines for filling up the voids created due to extraction of coal. The sand stowing process is the life line of the underground coal mining method in the highly populated Jharia Coalfield. Therefore, to ensure a continuous supply of coal and safe mining operations the sand collection and filling the underground mine voids is very crucial. Removal of sand from the river will have beneficial effect on the river also as it will help to improve the water flow and maintain its course. 2.4 Demands-Supply Gap The sand is being used by Jharia Division of Tata Steel for the stowing/back filling of its underground coal mines to avoid the subsidence. Therefore there is always regular requirement of the sand. 2.5 Domestic The sand collected from this leasehold will mainly be used for stowing purposes in the Jamadoba Group of collieries mainly Digwadih, 6&7 Pits and Jamadoba Colliery for captive use only. 2.6 Employment Generation This project operation will provide livelihood to the poorest section of the society. It provides employment directly to the people residing in vicinity and indirectly by the development of supporting infrastructure. 3 3 PROJECT DESCRIPTION 3.1 Type of project including interlinked and interdependent projects, if any The proposed project is for the collection of sand form the river bed with the help of Backhoe Dumper Combination. This project is required for fulfilling the requirement of sand needed for stowing /backfilling the voids created after extraction of coal in the coal mines of Jharia division of Tata Steel Ltd. 3.2 Location The mining lease area is located in Mouza – Damodarpur, Palkiri, Chatatand, Bhojudih, Narkera etc. Tehsil – Chandankyari District - Bokaro, State – Jharkhand The proposed project activity will be carried out in the bed of the river Izri and Gowai. The mining lease area falls in Survey of India Toposheet No. 73 I/6. Latitude: 23°35'N to 23°40'N Longitude: 86°25'E to 87°30'E 3.3 Details of alternate sites considered The lease for river bed sand mining is granted to the lessee by the State Government for its captive use of sand in underground colliery for stowing purpose. 3.4 Size or magnitude of operation The proposed mine has lease over an area of 50.17 ha. The total extractable material would be approx. 3.5 lakh tones per annum. 3.5 Project description with process details 3.5.1 Method for developing and working the deposits The sand deposited as river bed material will be collected in its existing form with the help of Backhoe -Dumper Combination. 3.5.2 Method of mining The mining is confined to collection of sand from the river bed. The operation will be Semi- mechanized in which the river bed material will be collected in its existing form. Excavation machines like backhoe along with hand tools like shovel, pan, sieve etc. will be used. Collection of sand will be carried out through the backhoe. Collection of sand from the riverbed material will be continued round the year except in monsoon for replenishment. 4 Working Depth (below ground level) The deposits occur in the bed of the river. During the lease period, the deposit will be worked from the top surface of sand to 2 m or above groundwater level whichever is less. The depth would be worked out based on the replenishment rate. 3.6 Raw Material Required Along With Estimated Quantity, Likely Source, Marketing Area of Final Product/S, Mode of Transport of Raw Material and Finished Product No raw material will be required in the proposed project. The operation involves the collection of sand in its existing form and loading into trucks, which will transport the material to the collieries. The existing roads will be utilized for the transport of sand from mine site to Colliery pit head. 3.6.1 Use of Mineral Sand is used for stowing/backfilling purpose in underground coal mines. 3.6.2 Mineral Beneficiation No mineral beneficiation is involved. 3.6.3 Surface Transport The transportation of sand will be carried out by the company though own transporter. There are all weather metalled road and then a kacha road right upto the leasehold to dispatch the material from leasehold to the collieries. It is loaded at leasehold site and transported through trucks/dumpers. The practice is quite conventional in the area and ensure continuous lifting of the material. 3.7 Resource optimization/ recycling and reuse Not envisaged. 3.8 Availability of water its source, energy/ power requirement and source 3.8.1 Water Requirement In the proposed project there is no need of water to carry out operations but drinking water will be required for the working people. This water will be supplied from the dug wells/bore wells in nearby villages. 3.8.2 Power Requirement All the activities will be carried out in a semi-mechanized manner.
