摘要:
针对香炉山大规模地下采空区，借助Voronoi图确定分摊面积来模拟矿柱荷载分布、矿柱破坏、荷载转移以及荷载重新分布的过程，从而确定现阶段的不稳定矿柱，并在此基础上考虑时间效应。用该方法可得出，目前香炉山钨矿不稳定矿柱的失稳不会造成大规模的坍塌，考虑时间效应，则20年时间效应内二四坑口的南区有发生连续坍塌的可能。为防止矿柱发生大范围坍塌，结合香炉山钨矿的实际情况，最终确定胶结充填法为该矿山当前处理空区的最适宜方法。
Abstract:
Territory area division was determined by the use of Voronoi diagram to simulate the load distribution, pillar collapse, load transfer and the process of redistribution, so that the current unstable pillar for largescale minedout area of Censer mountain could be determined. And the time effect was considered on this basis. It showed that the collapse of unstable pillars will not lead to a largescale collapse at present, nevertheless , there is the possibility of continuous collapse on no.2 and no.4 pithead southern district of Censer mountain Tungsten Mine in the next 20 years. In order to prevent the largescale collapse of pillar , the cementation filling method was determined as the most suitable method to treat the minedout area for the mine at present combining with the actual situation of Censer mountain Tungsten Mine
