Stability Analysis on Goaf Foundation Under Dynamic Load
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.
