摘要
通过对龙固煤矿21301工作面回采过程中利用松动预裂爆破配合煤机进行高档普采分析,对该面设备参数及爆破参数进行了合理的选择,为解决较硬煤层的快速开采提供了很好的途径。
This paper introduce basic principle of presplitting and loose bursting with roof coal,knows parameter of presplitting and loose bursting,it counts out theoretical value in 21203 workface Longgu coal mine with this principle combining application situation of other coal mine and festing again and gaain it gets out bursting parameter,super-conventional machine mining goes on smoothly,it has good vesult.
