摘要
结合具体工程实际,在分析工作面开采地质条件和相应技术条件的基础上,对预裂爆破机理和顶板预裂爆破方案做了逐一分析,并对顶板深孔预裂爆破技术的应用效果做了分析。结果表明,顶板深孔预裂爆破技术达到了预期效果,实现了对工作面空顶距离的有效控制,为生产作业的持续安全开展提供了积极的保障。
Combining with the concrete engineering practice,based on the analysis of the mining geological conditions and corresponding technical conditions of the working face,this paper analyzed the mechanism of pre-splitting blasting and the plan of roof pre-splitting blasting one by one,and analyzed the application effect of roof deep-hole pre-splitting blasting technology.The results show that roof deep-hole pre-splitting blasting technology has achieved the expected results,realized the effective control of empty roof distance of working face,and provided a positive guarantee for the sustainable and safe development of production operations.
