| 摘 要： | 安太堡露天矿东北角的井阳煤矿开采造成了大面积的地下采空区,为避免施工设备陷入采空区,须研究地面施工时动荷载对采空区的影响。本文按照时间顺序把该采空区划分三个区域,通过数值模拟计算分析了在动荷载作用下采空区内的变形、塑形破坏和应力分布状况,并对采空区上方施工安全性作出评价,最后提出采空区地基的处治对策。

| Abstract: | Large area of underground goaf caused by mining has appeared in JingYang coal mine of northeastern Antaibao opencast mine（open pit mine）.In order to avoid construction equipments falling into mined-out area,the effects of stability caused by ground construction in mined-out area were studied.In this paper,the goaf was divided into three regions according to time sequence.The deformation,plastic failure and distribution of stress were analyzed based on（by means of） numerical simulation under dynamic loading.The security of the construction technique above goaf was evaluated,and the control countermeasures（treatment measures） were obtained. |
