Abstract

Abstract

When two U-shaped ventilation working faces of shallow and near coal seams are mined in opposite directions, the series ventilation phenomenon that the above goaf is the main air leakage channel is easy to occur. In view of the situation of air leakage and combustion caused by series ventilation in 2206 working face of No. 3 well of Haiwan Coal Mine, the prevention and control technology of “leading and three-dimensional” coal spontaneous combustion is proposed. The air leakage and combustion dynamics of the goaf at the lower level of the working face are predicted by the way of advanced monitoring. The prevention and fire extinguishing technologies such as surface backfilling, roadway shotcrete, nitrogen injection inerting, retarder spraying and residual coal control are adopted to control the coal spontaneous combustion risk areas in the three-dimensional distribution of upper and lower coal seams. The results show that the phenomenon of series ventilation in 2206 working face is effectively controlled, and the spontaneous combustion of coal in upper and lower goaf is effectively suppressed.
