摘要: 中非矿业公司下辖谦比西铜矿西矿体含铜品位较高,顶板破碎,为典型的缓倾斜中厚难采矿体,设计采用上向分层充填采矿法进行回采。为探求其合理的采场结构参数,利用有限元软件ANSYS对采场不同布置方式时围岩的应力变形状况进行分析,确定了采场垂直矿体走向布置为最优回采方案,设计出9种典型采场结构模型,对其模拟结果进行优化比较,最终确定了合理的采场结构参数,即 4.3 m矿房,4.0 m矿柱。

Abstract: Chambishi Copper Mine, which belongs to Africa Mining PLC of China Nonferrous Metals Co., Ltd., is a high grade deposit and broken roof.It is the typical gently inclined medium-thick bodies.The cut-and-fill stoping mining method was adopted.In order to get the reasonable structure parameters, the stress and deformation condition in surrounding rock was analyzed in different stopes arrangement method by ANSYS.The optimal stoping scheme that stopes layout perpendicular to the ore body was determined.Compared with the simulated results of nine kinds of typical stope structure mode, the optimal structure parameters of stope as 4.3 m room and 4.0 m pillar is determined finally.
