Study on influencing factors of water outburst from coal seam floor based on IAHP-EWM game theory
In order to study the hydrogeology and management factors affecting floor water outburst,the analytic hierarchy model of 6 first-level indicators and 20 second-level indicators was established by literature research method.The index data of 8 water outburst accidents were collected.According to the analysis of the accident process and the cause of the accident,the 1～9 scale was used to reflect the influence degree of personnel management factor index on the probability and consequence of the accident.The interval analytic hierarchy process(IAHP)and entropy weight method(EWM)were used to analyze the collected data,and the game theory was used to combine the established indicators.The results showed that the thickness of aquiclude and the water pressure of aquifer had the highest weight in hydrogeological factors.The lack of geological basic data in management factors was the key factor affecting water outburst.Compared with other similar studies,the ranking results of index weight calculation had certain rationality,which provided a reference for the study of floor water outburst and provided a reference for the accurate prevention and control of water outburst from coal seam floor.
