摘要
要解决煤层自燃问题，破坏其漏风供氧环境能收到事半功倍的效果。柴里矿近年来在缓倾斜厚煤层冒落法开采条件下，通过宏观调控通风系统、优化改造区域通风系统和对局部巷段的漏风实施控制等技术手段来改善矿井通风环境，有效地控制采空区漏风供氧，提高了煤层自然火灾防治效果。
To solve the problem of spontaneous combustion in coal seams, the cutting－ off of air leakage and oxygen supply can get twice the results with half the effort. The improvement of underground ventilation environment in Caili Mine through macro regulation and control of the mine ventilation system, optimization transformation of district ventilation system and air leakage control in local roadways under the condition of caving mining of flat－ pitching thick seam has effectively made the air leakage and oxygen supply in the mining district under control and raised the control effect of spontaneous combustion in the coal seam.
