预裂爆破在井下回采中的应用与探索

扫码查看
地下采矿活动中,爆破作业是采矿的核心环节.回采作业的安全性,高效性、合理性等对后续的出矿、充填、运输等环节均有很大影响.面对现在井下回采进路断面规格成型差,对充填体影响大、存在粘夹矿等安全隐患的情况,对原爆破方式进行改进,将预裂爆破方式融合到现有的爆破作业中,进而控制进路宽度及两帮滑面,保证断面成型,减少后续的支护等作业,并为充填准备提供良好的作业条件,从而达到安全高效的回采作业.
Application and exploration of pre splitting blasting in underground mining
In underground mining activities,blasting operation is the core link of mining.The safety,efficiency and rationality of the mining operation have great influence on the subsequent ore-drawing,filling,transportation and other links.In the face of the present situation that the section specification of underground mining approach is poor,which has great influence on the filling body and has hidden dangers such as sticking ore.The original blasting method is improved,and the pre-split blasting method is integrated into the existing blasting operation,so as to control the width of the approach and the sliding surface of the two sides,ensure the formation of the section,reduce the follow-up support and other operations,and provide good working conditions for filling preparation,so as to achieve a safe and efficient mining operation.
