| 摘 要： | 乌兰矿矿区地表为脆弱草原环境，矿区开采环保条件要求严格，开采过程中须确保地表不发生较大位移。本文基于MIDAS/GTS、FLAC3D对乌兰矿塌陷坑进行数值模拟，同时结合地压监测系统获得的数据，对微震与应力数据进行分析，为乌兰矿采空区治理提供数据支撑，为矿山同类型情况提供借鉴。

| Abstract: | The surface of the mining area of Wulan Mine is a fragile grassland environment. The mining area requires strict environmental protection conditions. During the mining process, it is necessary to ensure that the surface does not have large displacement. Based on MIDAS/GTS and FLAC3D, this paper conducts numerical simulation of the collapse pit of Wulan Mine, and analyzes the microseismic and stress data in combination with the data obtained from the ground pressure monitoring system, so as to provide data support for the goaf management of Wulan Mine and provide reference for similar mines. |

| Keywords: | Collapse pit numerical simulation Micro-seismic Stress |
