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.
Coring ( diamond drilling) is another way of collecting information about a potential coal resource. The drill rig is equipped with a hollow tube, and as the drill pushes the rods into the ground, a cylindrical piece of the rock is pushed into the hollow tube. These samples are usually the length of a drill rod, which is 6 meters.
The machine is very useful in mines where seepage is excessive or where rain water forms muck, or where coal pillars are extracted by opencast method. It is quite convenient for cutting garland drains and sump. In Indian coal mines only small backhoes of capacity to m³ are used for special purposes stated above.
The system is called the sensitive drilling machine/press as the operator is able to sense the progress of drill with handfaced. Coal miningFrom Wikipedia, the free encyclopedia Jump to: navigation, search A coal mine in Bihar, India. The goal of coal mining is to obtain coal from the ground.
