摘 要:为了解决上盘不稳固缓倾斜矿体三角矿柱回采的问题,进行了预留矿柱小规格回采与诱导冒落联合回采方法的研究,得出预留矿柱可有效减少上盘暴露面积,控制塑性区的发展有利于维持上盘稳定,同时通过诱导冒落减少三角区域矿石损失,实现了对破碎上盘高品位三角矿柱的安全高效回采,为此类矿体回采提供参考。In order to solve the problem of unstable and gently inclined ore body triangular pillar mining in the hanging wall,a study was conducted on the combined mining method of small size reserved pillar mining and induced caving.It was found that reserved pillars can effectively reduce the exposed area of the hanging wall,controlling the development of the plastic zone is conducive to maintaining the stability of the hanging wall,and reduce the ore loss in the triangular area through induced caving,achieving safe and efficient mining of high-grade triangular pillars in the fractured hanging wall,providing reference for the mining of such ore bodies.
