Proper mine dewatering is a critical component to every successful mining operation, regardless of the type of mining that is being done. If the pumps used for dewatering are too small or there is an insufficient number of them, there is a possibility of being flooded out and losing critical equipment and operational time.

Coal miners use two primary methods to remove coal. Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are …
This test is used to find a break in one of the cable conductors. The principle of the test is to compare the capacitance of one part of the faulty conductor, with the capacitance of the whole of a sound conductor. The methods is as follows: 1. Isolate both ends of the cable and discharge to earth. 2.
