    Grouting Control Technology for Spontaneous Combustion Area in the Deep of Waste Dump of Daliuta Coal Mine

      摘要
    • 摘要: 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。

       

      Abstract: In this paper，by using ground drilling grouting to isolate deep fire area in the waste dump, cutting off the CO diffusion channel and covering sand to cut from the fire area oxygen conditions, the threat of deep spontaneous combustion area in the waste dump to mine safety production is seffectively relieved.
