摘要
Abstract
Aiming at the characteristic of the big risk, the closed and unsealed dififculties of ifre zone in for high gassy and easy spontaneous combustion coal seam fully mechanized caving mining in the process, after analyzed the ignition process and the causes of Xing'an Coal Mine three level North 18 layer working face of, taken water seal isolation, reinforcing and sealing, not only timely and effectively reduced air leakage in the working face, and also effectively governed the ifre area, which ensure the smooth unsealed.关键词
