Application of Fuzzy Comprehensive Evaluation on Coal Mine Roof Accidents in Yulin Area
The coal seam of Yulin mining area typifies shallow,thick loose bed,which characterizes intense strata pressure.A fuzzy comprehensive evaluation model is set up by mass observation on spot and analysis of the affecting factors of the roof accidents in Yulin mining area,involving 18 indicators pertaining to four sections:the control of roof,the stability of coal wall and roof,and the means of support.The research on the roof accidents of four mines in Yulin indicates that the model covers the major causes of roof accidents in the area.With the application of the model,the potential hazard can be identified and the control of roof accidents in Yulin mining area can be supervised effectively.
