摘要
随着露天煤矿开采深度的逐渐加大,受多种条件的影响,水孔越来越多,针对水孔对爆破质量的影响进行分析,找出影响爆破效果的主要因素,从优化爆破设计,正确选用炸药种类,改善装药结构等方面提出解决水孔的具体方法,提高爆破质量。
With the gradual increase of mining depth in the opencast coal mine,affected by many conditions,water hole is increasing,this article analyzes the influence on the blasting quality of water holes,find out the main factors affecting blasting effects,put forward to specific methods to solve the water holefrom the blasting design optimization, the correct selection of explosive type, the improvement of chargestructure and improve the blasting quality.
