Unregulated underground group mining in China has led to problems such as unclear locations and complex shapes of mine goafs mineral engineering, posing serious safety hazards for subsequent operations. This paper takes engineering with the research object, integrates multi-survey data from surface deformation remote sensing monitoring 3D laser scanning measurement survey area where rate reaches 14cm/ year, accurately identifies location risky goafs, constructs detailed representations real inside engineering. The FLAC3D 6.0 software is used establish a numerical simulation model fully considering process, conducting characteristic analysis stress distribution, failure range response revealing impact void on stability mine. results are combined on-site investigations verify whether geological disasters have been caused by goafs. methods can provide effective technical means assessment which help reduce risk mines improve
