摘要
Abstract
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 pil-lars can effectively reduce the exposed area of the hanging wall,controlling the development of the plastic zone is conducive to maintai-ning 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.关键词
