Abstract:Intelligent construction of fully mechanized mining face has become an important development direction of coal mining in China. The traditional safety evaluation of fully mechanized mining face has been relatively mature，and the safety evaluation system of intelligent working face needs to be enriched.By comparing the system characteristics of traditional and intelligent working face，this paper systematically analyzed the safety factors and hazard sources under the background of intelligent workingface，28 indexes from four aspects of human，machine，environment and management were selected，the safety evaluation index system was established，and the safety evaluation calculation model based on entropy weight method and extension theory was constructed. Taking a mine in Shanxi as an engineering case,MATLAB was adopted to calculate and evaluate the safety level. The research results showed that the evaluation index selected in this paper had good independence and comprehensiveness , which was in line with the engineering practice;the entropy weight method could reasonably distribute the index weight,and the extension theory could analyze the correlation coefficient between each layer index and the safety level,so as to accurately calculate the safety level of intelligent working face. Extension theory of entropy weight could provide important ideas and means for safety evaluation of intelligent working face.

Key words:intelligent fully-mechanized working face ; evaluation index system；entropy weight; extension theory；safety evaluation
