1. Introduction. Coal is an important energy resource, and has produced around 40% of the annual world's electricity [1].As coal reserves are far more abundant than other fossil fuels in the world, coalfired power plants are expected to still play an important role in electricity production in the foreseeable future, although renewable energy sources are developing rapidly [2].

The continuous miner technology (CMT) is being adopted extensively in underground coal mines of India as mass production technology. This technology potentially eliminates the twounit operating, namely the drilling and blasting. This elimination helps for better strata control and avoids the drillers working in unsafe conditions, maybe under the loose coal roof. This CMT improves the quality ...
