摘　　要：基于现场地质调查和室内试验得到的矿岩力学参数,根据工程地质特点和开采技术条件,运用数值模拟软件建立了开采数值模型,对矿体开采和充填进行了模拟分析,得到了每中段的应力和位移场的分布情况。结果表明,充填可以有效抑制围岩的应力和变形,提高围岩或矿柱的承载能力,起到了稳定采场的作用。Based on the rock mechanics data from the on-site geological survey and laboratory test,engineering geology characteristics and mining technology conditions,the simulation analysis on ore body mining and filling was proceeded with the exploitation numerical model established by numerical modeling software,the distribution of the stress and displacement field for each mining level has been obtained.The results shows that filling can control effectively the stress and transformation of surrounding rock,improve the bearing capacity of surrounding rock and jamb,which has the effect of stabilizing stope.
