海下采煤工作面的防灭火有其特殊性,主要体现在其地表(海面)的接近困难,无法从地表钻孔进行灌浆。一旦海下采煤工作面发生火灾,也无法采用地表钻孔进行注浆或注水灭火。分析了我国首个海域开采面H2101面停采撤架期间可能发生火灾的原因,根据矿井实际情况,重点介绍了建立预测预报系统、合理配风、井下隅角注浆、注凝胶等综合防治措施。对各种措施所取得的效果进行了评价,这对海域开采防治煤炭自燃具有很好的借鉴作用。
Fire prevention and control of coal mining face has its own particularity, mainly reflected in its surface (sea) near difficulties, not from the surface drilling for grouting. Once the coal mining face under the sea fire, it can not use surface drilling for grouting or water injection fire. Based on the mine actual situation, this paper mainly introduced the establishment of forecasting and forecasting system, rational distribution of air, underground corner grouting, grouting and other comprehensive prevention and control measures Measures. The effectiveness of various measures was evaluated, which is a good reference for the prevention and control of coal spontaneous combustion by sea mining.
