挤压爆破崩落采矿法在锡铁山铅锌矿的应用

摘要

The stability of hanging wall surrounding rock of the stope located the east of 35 exploration line at 5 level of Xitie Mountain lead-zinc mine is poor. According to this problem, the extrusion blasting caving mining method was applied in 501 stope located the east of 5 level. The caved rocks played a very good supporting function on surrounding rock of the stope, thus the large area surrounding rock falling have gotten effective control and good effect was obtained, which can be referred by safety production of the similar mine.%锡铁山铅锌矿深部五中段35勘探线以东采场上盘围岩稳定性较差,针对这一难题,对该中段东部的501采场采用了挤压爆破崩落采矿法进行回采.崩落的矿石对采场围岩起到了很好的支撑作用,从而有效地控制了围岩的大面积冒落,取得了较好的效果,为类似矿山的安全生产提供借鉴.
