Question

name any three major problems of coal minning industry.

Answer 1

If the coal seam reaches a fault, the seam may be significantly displaced, depending on the type of fault and its offset. Machinery trying to mine the coal may not be able to reach the displaced seam, if the displacement is too large. Coal mines use a combination of boreholes and high-resolution seismic reflection data to identify the larger faults and avoid the most faulted areas at the mine planning stage.

Answer 2

•Mine operators don’t have a means to estimate the minute-to-minute status of mine conditions or the location of their workers.

•Combustible materials, a natural byproduct of mining, can damage equipment if not evacuated promptly.

•Even with modern headlamps, visibility is often poor inside mines.
