摘要
为防止王家岭新井在石门揭煤时发生煤与瓦斯突出,在掘进头进行了突出危险性预测和消突,根据煤层赋存条件选用导硐震动炮法进行揭煤,设计了导硐的层位、尺寸及其爆破施工参数,并用震动炮安全完成揭煤作业。
To prevent coal and gas outburst during the period of cross-cut coal uncovering,the outburst fatalness was predicted,the result showed that gas outburst might be occurred at the cross-cut face.The dimension of pilot tunnel,layout of vibration shot blast holes and blasting parameters were designed based on the coal seam geological conditions.The cross-cut coal uncovering was successfully completed.
