The order constitutes the first continuous miner equipment ever to be used in India's Eastern Coalfields and represents a big breakthrough. The Jhanjra mine has operated many different longwalls (British, Chinese and Russian) for many years, but the equipment is very old and production rates are extremely low by world standards.
The stateoftheart technology of the continuous miner (CM) deployment is a unique method to extract coal seam lying at greater depth with higher seam thickness, minimising the loss of coal in terms of in situ pillars and continuous production rate.
The cost, complexity, lack of filling space and time create challenges in the longwall backfill operation, resulting in poor subsidence control and reduced productivity. This paper proposes an automated continuous mining and continuous backfill (CMCB) method by examining its key requirements and investigates the optimum sequence of coal panel (such as drifts) excavation to ensure ground strata ...

The accurate prediction of surface subsidence induced by coal mining is critical to safeguarding the environment and resources. However, the precision of current prediction models is often restricted by the lack of pertinent data or imprecise model parameters. To overcome these limitations, this study proposes an approach to predicting mine subsidence that leverages Interferometric Synthetic ...
