煤矿岩巷中深孔掘进爆破试验研究
|
摘要
针对煤矿普遍存在的中硬岩爆破效果差的问题,分析了煤矿中硬岩巷道掘进爆破效果的因素。经过新月矿中硬岩石巷道典型工作面中深孔爆破试验研究发现,在条件允许的工作面采用直眼楔形复式掏槽,连续不耦合装药,掏槽眼反向起爆进行掘进爆破的方法具有较优的掏槽效果和较高的安全性,取得较好爆破效率和光爆效果。试验成果可供其他类似工程提供参考。
The influence factors of driving blasting were analyzed,aiming at the problem of bad effect in rock blasting at coal mine.The techniques of using Lewis cut and seriate no-coupling load drug and trenching reverse blasting have better effect and higher security.The effects include blasting efficiency and light blasting effect.The Experimental production may provide reference for other analogous engineering.
