摘要
本文以某矿1307工作面为研究对象,分析了薄基岩留底煤采场冲击地压诱发煤与瓦斯突出的机制,并推导了发生复合型自然灾害的极限载荷,采用抽放瓦斯内能、释放煤岩体弹性变形能、煤层注水的方式进行防治,并对防治措施采用钻屑法进行效果检验,取得了良好的效果,有效预防了冲击地压诱发煤与瓦斯突出的灾害。
This paper takes 1307 working face of a mine as the research object, the mechanism of coal and gas outburst induced by rock burst in thin bedrock bottom-retaining coal stope is analyzed, the ultimate load of compound natural disasters is deduced, and the prevention and control measures are adopted by draining gas internal energy, releasing elastic deformation energy of coal and rock mass, and injecting water into coal seam, the effect of drilling cuttings method is tested and good results are obtained, the disasters of coal and gas outburst caused by rock burst are effectively prevented.
