摘要: 通过对海石湾煤矿掘进工作面实际情况及煤与瓦斯突出预测方法的介绍,结合该掘进工作面实际情况,确定了煤与瓦斯区域防突方法及局部防突方法,并就其防突方法所达到的效果进行了分析。结果表明:根据该矿实际情况得到开采保护层的有效保护范围依次为,垂距最大为50m,沿倾向为130m,沿走向为50~100m;运用区域防突及局部防突措施后,进行效果检验得出相应指标为:VCH4=7.59 m3/t,S=0.52Kg/m,K1=0.41ml/g?min1/2,说明掘进工作面前面已无突出危险性。

Abstract: Based on the introduction with the actual situation of driving workface and prevention coal and gas outburst. The methods of regional and locality prevention coal and gas outburst were determined and effeteness validation analysis. The results are shown that effective protection range of mining protect coal seam are the maximum vertical distance(50m), vergence direction(130m) and strike(50~100m); using the regional and locality prevention methods the indices are VCH4=7.95 m3/t, S=0.52Kg/m,K1=0.41ml/g?min1/2,it is shown that coal and gas outburst risk of the driving workface is eliminated

Key words: driving workface, coal and gas outburst, measures prevention
