摘要
为了研究板庙子金矿北区深部矿体开采对上盘斜坡道稳定性的影响,通过分析北区矿体的赋存条件,初步提出4种矿体回采方案,并对4种方案进行了数值模拟,采用地表倾斜i、地表曲率k、地表水平变形ε3个指标作为4个方案优选的评价指标,通过模拟分析计算,最终确定方案一为最优方案,按此方案回采后的斜坡道扰动最小。
In order to study the impact of deep ore body mining in the northern area of Banmiaozi Gold Mine on the stability of slope ramp in hanging side,four mining schemes were preliminarily proposed by analysing the occurrence conditions of ore body in the northern area,and were analyzed by numerical simulation.Three indicators of surface inclination i,surface curvature k and surface horizontal deformationεwere used as the optimal evaluation indexes of the four schemes.The simulation analysis and calculation showed that the No.1 scheme was the optimal solution with minimal disturbance to the slope ramp.
