摘要
介绍了岩巷揭穿突出危险煤层的施工程序 ,指出施工中应准确确定安全岩柱厚度 ,要对突出危险性进行预测 ,还应采取排放瓦斯钻孔技术防止瓦斯突出 ,同时应注意采取措施后效果的检验 ,可采用震动放炮的施工方法 .
It has introduced the process of opening the outburst seam in roadway and pointed out that it is neccessarily to determinating the thickness of safety rock colum performance.It should predict the outburst and adopt some measures to exhaust gas.In order to make sure the result of the measures,the performance of shock blasting is needed.
