摘要
针对冬瓜山铜矿千米深井矿床矿体和围岩的力学特性和地质特征,介绍了矿房采场束状深孔爆破方案的参数选择、装药连线结构及工艺;在束状深孔爆破应用的基础上,通过采场爆破方案的调整,对提高采场爆破主要经济技术指标和有效控制爆破效果起到了积极的作用。
According to the mechanical properties and geological features of ore body and its wall rock in 1000 meter′s deep shaft of Dongguashan Copper Mine,the selection of bunch-long-hole blasting scheme is introduced in this paper.The design of blasting parameters,charge structure,priming network and technique for room stope is introduced.Based on the application of bunch-long-hole blasting technique and the adjustment of blasting schemes,the blasting technical and economic indexes,as well as the control effect for blasting,can be improved.
