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。
This paper analyzes the influence of the main factors such as geological structure, coal burial depth, coal metamorphism, coal and surrounding rock permeability on the horizontal coal and gas outburst in Furong Coal Mine. The parameter testing is emphasized, and the possibility of protruding areas B3 + 4 in the horizontal mining is analyzed by the method of regional prediction.
