摘要
根据许疃煤矿83下山巷道断面和岩石性质,采用中深孔光面爆破方式,对爆破参数进行设计,精心组织施工。结果表明,应用研究取得了良好的效果。
According to the rock diphead section and property of the rock, using mid-deep hole smooth blasting technique, the blasting parameters were designed and the construction was well organized. The results show that the application has good effect.
