摘要
分析了地质构造、煤的埋藏深度、煤的变质程度、煤与围岩的透气性等主要因素对芙蓉煤矿下水平开采煤与瓦斯突出的影响,通过对下水平B3+4煤层煤与瓦斯突出参数测试,应用区域预测方法分析了下水平开采B3+4煤层区域突出的可能性。
In this paper the effect of stratum tectonic the depth of coal seam the metamorphose degree of coal and the gas permeability of coal and surrounding rock on coal and gas outburst of the second level tunnel in Furong Coal Mine is studied. The regional outburst probability of B3+1 coal seam of the second level tunnel is analyzed by regional prediction method based on the parameters of coal and gas outburst of the second level tunnel acquired in site test.
