摘要
某大型采石工程对规格石的要求严格,为降低爆破石粉含量,根据采场地质结构及生产条件,经现场试验及效果分析,将采场岩体进行了分级,针对不同类型岩体采用不同的爆破参数及径向不耦合连续装药或不耦合分层装药的爆破技术,满足了工程要求。
The requirement of dimension stone is strict of a large exploitation engneering.For reducing the content of rock flour,Based on the site test and result analysis,with consideration of geological conditions and production capacity,the rock was classified and the different blasting parameters and radial un-coupled continuous charge method or un-coupled separate zone charge method was applied in different rock body for engneering requirement.
