摘要
综合了国内多家同类工程的经验并结合桐柏地下厂房实际地质情况,确定了厂房上部合理的开挖分层方案和边墙预裂方法。进行了垂直孔或水平孔光爆以及垂直孔预裂等开挖方案试验,通过不同开挖方案爆破效果的分析和比较,最终确定了岩台的最佳开挖施工方案、最佳炮孔布置、最佳装药结构和其他相关的爆破参数。
Domestic experience much same projects are summarized and the actual geological situation of Tongbai underground house are combined. The reasonable excavating layering scheme of house upper part and the means of cracking beforehand along the wall are determined. The excavation schemes such as smooth blasting with vertical or horizontal holes and presplitting with vertical holes are tested. Through analyzing and comparing the blasting results of different excavation schemes, the optimal methods of rock excavation ,the optimal layout of bore hole, the most effective formation of explosive charge and other relative blasting parameters are determined.
