公乌素矿煤层自燃原因分析及防治技术

为了有效地防治公乌素矿煤层的自燃,本论文通过对1604工作面煤炭自然发火原因分析,提出了以注浆防灭火技术为主,束管监测技术预测、注氮防灭火技术作为补充的综合放灭火技术措施。实践应用表明,该措施能够有效地控制该矿工作面煤层自燃的现象的发生。

In order to effectively control the spontaneous combustion of GONG WUSU mine, This paper through the GONG WUSU 1604 coalface of coal mine of the coal spontaneous combustion reason analysis,Put forward by comprehensive fire - prevention technology measures, the fire -prevention of the grouting technology is given priority to, tube monito- ring technology forecast, fire - prevention technology by infusing nitrogen as a supplementary practice application shows that the measure extinguishing effect obviously.
