摘要
针对综掘巷道遇硬岩时,切割速度慢、成本增加的现状,本文在松动爆破机理分析的基础上,提出了先行深孔松动爆破、再采用综掘机切割的施工方案,通过现场的试验取得了很好的效果,证明了方案的可行性,为类似工程提供了借鉴。
For the situations which encountered in the actual construction process of hard rock in comprehensive digging roadway,such as slow cutting speed,increased costs,this article bases on deep hole loose blasting theory analysis and calculation,puts forward a rational program which first carrying on deep hole loose blasting and then cutting by machine.We have achieved well experimental effects by the field test and proved the feasibility of the program,to have an important reference works in similar projects.
