摘要(Abstract)：

采用浅孔分层微差爆破方法明挖胶带机系统机头暗道。文中讨论了爆破参数和单孔药量的计算。根据爆破安全规程中规定的爆破震动和冲击波安全距离 ,确定了一次齐爆的最大药量。此外还介绍了起爆网路、爆破施工中应注意的问题以及瞎炮的处理方法
By short hole millisecond blasting method,a rock tunnel for head of the belt conveyor was open excavated The calculation of blasting parameters and single hole charge weight was discussed According to the safety distances for blasting vibration and shock wave provided for in Blasting Safety Regulations,maximum charge weight per delay interval was determined In addition,the priming circuit,the issues noted in blasting process and misfire removal method were presented
