Historically speaking, underground mining not only saves the mining area's original form but also gives the mining company higher revenues. According to MiningGlobal.com, longwall mining, a type of underground mining that utilizes a longwall shearer, accounts for 50 percent of coal mines in the world and is much safer than other methods of coal mining.
Underground mining is when the coal is farther underground, making it too expensive to remove soil. In this process, coal miners and all of the coal mining equipment are brought deep underground and coal is carried up out of the ground.

The gloomy scenario of coal production along with the likely exhaustion of shallow depth coal reserves and problems faced regarding surface land acquisition for opencast mining have warranted a quantum jump in coal production and productivity from underground mines in India.
Underground soft rock mining is a group of underground mining techniques used to extract coal, oil shale, potash and other minerals or geological materials from sedimentary ("soft") rocks.  Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in ...
