Objectives of Mine Development
|
|
|
- Design and plan an economical method for production of coal as per requirement of quality and size for the total period envisaged for the life of mine.
- Minimize the lead of overburden required to be removed from quarry to dumping place/backfilling and transportation of coal.
- Ensure to effectively implement the Environment Management Plan appropriately so as to curtail impact on environment.
- Make arrangement to feed ROM(Run of Mine) coal of (-) 200mm size to the thermal power plants as per requirement.

Scope of Work of Mine
|
|
|
- Design and Development of the mine in the shortest possible time period along with other connected activities required for operating an cost effective mine
- Design, Construction & Maintenance of Haul roads for disposal of Overburden, Coal transportation roads to transfer point for coal
- Design, Construction & Maintenance of suitable water sump of sufficient capacity and installation of commensurating pumping out arrangement so as to ensure that mine is always operational even during the monsoon period.
- Removal of Overburden & Excavation of coal by deployment of HEMM in such a Shovel/Dumper combination so as to achieve optimum production
- Design, Construct & Maintain workshops for HEMM, Effluent Treatment Plant & stores for lubricants and maintenance spares.
- Design and construct Magazine for explosive stowage as per explosive regulations in vogue and arrange procurement, storage & transportation of explosives and other explosive detonating accessories and material. as per requirement of the project
- Design, Install and maintain Coal Handling Plants (CHPs) for crushing & screening of appropriate required capacity to ensure delivery of
- (-) 200mm size of coal
- Design, construction and maintenance of other infrastructure such as HT/LT Sub-station for electrical power supply including provision for standby captive power supply by installing appropriate capacity of Diesel Generating sets
- Design, Construction and maintenance of civil infrastructure such as administrative block, hostel, residential accommodation, canteens, dispensary, Rest shelters for workers , bath & toilet facilities and water arrangements
- Creation of proper communication system for use of all working in the concerned mine
- Conserve the top soil by excavating it and stacking it separately, to be utilized for covering the top of reclaimed de-coaled mine area for plantation of trees
- Back filling of de-coaled areas, reclamation of void area duly back filled & OB dumps by spreading top soil.
- Proper design of benches in the mine & OB dumps as per current regulations stipulated by Director General of Mine Safety (India) and nature of soil
- Illumination of whole Mine adequately including working area and provision ofor fencing of quarries & digging of garland drainage system all around mine so as to prevent the mine from flooding during rains
- Preparation of mine decommissioning plan five years before its actual closure & implement the same as required
- Implementing progressive & final mine closure plan
- Compliance of various statutes in respect of coal Mining.

Mining Methodology
|
|
|
- Overburden removal & coal excavation is done in the mine by deployment of appropriate size and type of shovel dumper combination so as to achieve optimum production
- Top soil is taken to designated area for stowage. It is stacked in such a manner that it is not contaminated by other O.B. material i.e. hard rock etc
- Top soil is eventually utilized for reclamation
- Drilling in OB/coal to be done by using appropriate drill rigs
- Blasting in OB/coal id done by qualified engineers as per laid down rules
- Exposed coal shall be excavated by Continuous Surface Miner/shovel and transported by dumpers to C.H.P. for crushing as required.
- Prepare mine decommissioning plan five years before its actual closure & start implementation of the same appropriately.
