摘要
本文首先根据矿体赋存条件和矿岩体稳固情况,对南平钽铌矿475m水平以上的31#矿体进行了开采区段划分,提出了相应的采矿方法和采场结构参数,并采用专家系统方法,预测了采场顶板和矿柱的稳定性和可能的破坏模式;在此基础上,采用数值模拟方法,对采场结构参数和回采顺序进行了优化,确定了适用于31#矿体的采场结构参数和矿体回采顺序,并给出了475m水平以上31#矿体的矿块布置方案。
According to depositing condition of ore-body and stability of ore-body and wall-rock, 31# ore-body up level 475m of Nanping Ta and Nb Mine is grouped into 13 mining segments in this paper. Min- ing methods and structural parameters is proposed. Stability and possible failure mode of stope ceiling and pillar is predicted by means of expert system. On the basis of above, structural parameters of stope and mining sequence is optimized by numerical simulation method. Thereby, the structural parameters of stope and mining sequence of 31# ore-body is determined. Finally, layout of stoping segment which is suitable to 31# ore-body up level 475m is put forward.
