摘要
为达到既能有效松动岩体,同时又降低爆后岩石的大块率,提高爆破能量的利用率,提出了煤层综采面底板岩石松动爆破技术参数(炮孔装药量、炮眼深度、抵抗线、炮眼密集系数、装药结构和炮孔堵塞等参数)设计和优化的方法;通过刘庄煤矿综采面煤层底板岩层深孔松动爆破现场试验,确定实际松动爆破技术方案和爆破参数,取得了良好的爆破效果。
In order to loose rock effectively,reduce the rate of large rock and improve the utilization of blasting energy at the same time,this paper puts forward the methods for design and optimization of parameters（charge of borehole,depth of borehole,ultimate burden,density of borehole,construction of charge,stemming of borehole and so on） of the loosen blasting for bottom floor rock of fully-mechanized face in coal.Commercial test in Liuzhuang coal mine has been proceeded,which define the actual blasting scheme and factors of the long hole loosen blasting for bottom floor rock of fully-mechanized face in coal seam,and good results have been got.
