What are the effects of mining limestone on the environment?
The greenhouse gases produced in the process of mining and in the manufacture of cement from limestone are the great concerns for the environment.
Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sink.
