Development Of The Angren Coal Deposit, Prone To Spontaneous Combustion

Аннотация

The article discusses the features of the development of powerful coal seams prone to spontaneous combustion. The conditions for the development of coal self-ignition processes and ways to combat endogenous fires, most of which occur in the developed space of mines. The increase in the volume of mined-out space and depth of mining operations, as well as the lack of accurate methods for determining the location of fires, reduced the effectiveness of the fight against spontaneous combustion supply of liquid compounds such as water and clay pulp flowing down the soil layer. For the prevention and suppression of foci of spontaneous combustion is increasingly being used as a nitrogen supply which produces a three-dimensional processing of the milled mass and reduces the oxygen concentration in the produced space.
