| 摘 要： | 针对某缓倾薄层石膏矿顺层巷式开采采场围岩结构的典型特征,结合对采场坍塌破坏的离散元数值分析,综合制定了适用于该矿的收敛监测测点布置方式。新测点布置方式充分发挥了数值模拟在定性上的优势和收敛监测在定量上的优势,测点布置更具科学根据性,使获得的监测数据更为可靠,更有说服力,对于准确评价采场与矿柱稳定性具有重要意义。

| Abstract: | In the light of typical structure characteristics of surrounding rock in roadway mining along ore bed of some gently-inclined and thinly-bedded gypsum mineral deposit,according to distinct element analysis of the stope collapse,a new arrangement of convergence monitoring points of stope was established.The new arrangement of monitoring points fully brings out the advantages of numerical simulation in quality and the advantages of convergence monitoring in quantity,so is more scientific and can obtain more reliable data to accurately evaluate the stability of stope and ore pillar. |
