封堵灵复合水压爆破在施工中的应用

Construction application of plugging spirit compounding water pressure blasting

把传统水压爆破与矿山封堵材料——"封堵灵"结合,总结出复合水压爆破技术。通过数值分析法,分析采用常规爆破、水压爆破、复合水压爆破的每循环的炸药用量等参数,从缩短循环时间、降尘、炸药消耗、光爆效果等四方面进行效果分析和经验总结。

This paper,creatively combining the traditional water pressure blasting with mining plugging material-＂plugging spirit＂,makes a summary of composite water pressure blasting technology. Through numerical analysis,it analyses parameters such as explosive consumption of each cycle in conventional blasting,water pressure blas-ting and composite water pressure blasting. This paper analyses the effect and sums the experience in four aspects such as shortening the cycle time,falling dust,explosive consumption and smooth blasting effect.
