Abstract

Goaf has become a major hidden danger affecting mine safety production.In order to accurately analyze the stability of complex goaf group and strengthen the safety control of goaf group in mine,based on the fine detection data of goaf group in a mine,a coupling modeling and numerical simulation analysis method of Geomagic,Midas GTS and FLAC3D was adopted to analyze the stability of complex goaf group.At the same time,the safety classification evaluation system of complex goaf group was established based on 16 indicators such as goaf type,rock compressive strength and exposed area,and the safety classification evaluation of complex goaf group was carried out.The results show that there are caving hazards in the hanging wall and southeastern roof of large ore body goaf.The ‘springboard’ rockmass in the northwest of the panel-5 will be deformed greatly in the process of residual ore mining.There is great stress concentration in the inter-pillar separated by each goaf in the main mining area.Combined with the safety classification evaluation results of goaf,the treatment measures of each goaf are proposed.The research results provide reference for the stability analysis and safety classification evaluation of mined-out areas in similar mines.
