通过地面打钻注浆隔离矸石山深部火区、切断CO扩散通道和覆盖沙土隔绝火区供氧条件的方法,有效地解除了矸石山深部自燃火区对煤矿安全生产的威胁。
Through drilling and grouting on the ground to isolate the deep fire area of the waste rock, cutting off the diffusion channel of the CO and the method of covering the oxygen supply conditions of the sand cutoff fire area, the threat to the coal mine safety production from the deep spontaneous combustion fire area of the waste rock was effectively relieved.
