缓倾斜中厚矿体破碎上盘高品位三角矿柱联合回采技术应用OA
Application of Joint Mining Technology of High-Grade Delta Pillar in the Crushed Upper Plate of Gently Dipping Medium-Thick Ore Body
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 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 i…查看全部>>
