Mine Waste as Resource: Indian Mining Scenario of Coal and Non Coal Mining Sector

Fundamentals of 3D modelling and resource estimation in coal mining

The prerequisite of maintaining an efficient and safe mining operation is the proper design of a mine by considering all aspects. The first step in a coal mine design is a realistic geometrical modelling of the coal seam(s). The structural features such as faults and folding must be reliably implemented in 3D seam models. Upon having a consistent seam model, the attributes such as calorific val...

Methane Mitigation in Indian Coal Mining

Association of methane with coal poses a serious explosion risk in underground coal mining. Besides, it is a potent green house gases significantly contributing to global warming. Therefore, its commercial exploitation is being widely recognised as (a) a fuel resource to bridge the energy gap (b) making coal mining safer (c) providing cleaner energy and (d) checking the building of green house ...

An Innovative Longwall Mining Technology in Tangshan Coal Mine, China

In mining of inclined coal seams in Tangshan coal mine of Kailuan group, gateways on either end of a panel were both typically located along the floor and a gateway pillar between adjoining panels was left unmined between adjacent panels to ensure stability, thus forming a planar mining system. According to the practice, however, it turned out that this conventional mining system has long-stand...

The Status of Ndt Techniques in Indian Coal Mining Industries

Introduction: India with hard coal production of about 254 MT from about 550 nationalised mines in 1994-95 is the third largest coal producing country in the world after China & USA. The country with 16.4 percent population of the world has measure 6.8 percent share of proved world coal resources. Coalfield over an area of 4.37 million hectares out of the total land surface of 328.8 million hec...
