优化炮眼布置方案提高钻爆掘进效果

Optimizing the Layout Plan of Blast Hole and Enhancing the Effect of Drilling Blasting Excavating

钻爆法是小煤矿巷道掘进的主要手段,结合工程实践,阐述了在井巷掘进施工中,合理选择炮眼布置方案并进行优化,可以提高爆破效果,提升工程质量,加快巷道掘进速度,保证采掘关系的协调。

Drilling blasting method is a major means of small coal mine laneway tunneling. Combined with the engineering practice, the paper expounds the reasonable layout plan of blast holes and optimizing in the laneway tunneling construction, which would improve the blasting effect, increase the engineering quality, accelerate the advance rate of laneway and guarantee the mining relationship coordination.
