深孔挤压抛渣掏槽爆破法在采区煤仓施工中的应用

The application of cutting explosive method of discarding cinder in deep-breast-hole in section coal bin construction

由于采区煤仓传统施工方法存在许多问题 ,在此介绍了深孔挤压抛渣掏槽爆破法在古汉山矿采区煤仓施工中的应用 .通过总结古汉山矿煤仓施工经验 ,提出了深孔挤压抛渣掏槽爆破法及相关的掏槽参数、爆破参数和安全技术措施 。

There are some problems in the conventional conctrution methods in the coal bin of mining area.A better method for performace in the coal bin of mining area is introduced,that is the cutting explosive method.By summarzing the construction experiences of section coal bin in Guhanshan coal mine,the authors have put forword the cutting explosive method of discarding cinder in deep*.breast*.hole and its related cutting parameter,explosion parameter and safety and technical measures,Thus,some valuable experiences for similar cases hav been provided.
