Abstract.

Basic characteristics of the methane impulse emissions into the face of the roadways were studied at the rock caving in zones with geological faults intersecting are considered. Usually, the methane impulse emissions occur suddenly, spontaneously and often lead to increased, up to explosive, methane concentrations. As a rule, methane emission can be increased by 6-35 times in event of gas breakthrough from the roof, and can reach its maximum (up to 77m³/m) within a short period of time. Then discharge of the escaping gas gradually decreases. It was found that the most intensive gas emission occurs when rocks fall in area being under the effect of plicated faults (usually it is anticlines, domes, brachyanticlines, flexures) from fractured-porous manifolds. Key examples of the face impulse gassing during the mining operations are considered.

Keywords:

methane emission, geological fault, impulse character.
