摘要：

摘要:应用现场混装乳化炸药技术，对碱沟煤矿急倾斜特厚坚硬顶煤实施深孔爆破，对顶煤进行弱化处理。结果表明现场混装炸药技术在碱沟煤矿应用中取得了良好的效果，对顶煤裂隙发育和顶底板两帮变形监测，并阐述了爆破工艺过程、爆破参数的选择。

Abstract:Using sensitised emulsion explosive technique in JianGou hard top coal imply Middle-long hole blasting and weakening of top coal. The results show site sensitised emulsion explosive technique achieving good results in JianGou coal, we monitor to top coal fractured and the roof、the floor and the two sides deformation monitoring, then description of the blasting process and selecting of blasting parameters.
