摘要
井巷的掘进效率和成巷质量对后期煤炭开采效率和安全性具有重要意义。在分析井巷爆破机理的基础上,以0305工作面底抽井巷的掘进为例,对其爆破参数进行优化设计,并对爆破参数优化后炮眼利用率、循环进尺以及炸药消耗量进行对比分析,以验证爆破参数的爆破效果和效率。
The tunneling efficiency and lane quality have great significance to the efficiency and safety of the later coal mining.Based on the analysis of the blasting mechanism of the well lane,the excavation of 0305 optimized the blasting parameters,and compared and analyzed the muzzle utilization rate,circulating ruler and explosive consumption after optimizing the blasting parameters to verify the blasting effect and efficiency of the blasting parameters.
