This paper analysises and evaluates man-machine-environment system safe in mine and gives the general procedure for man-machine-environment system safe in mine, which contain determination of each evaluation matter-element and comprehensive evaluation method based on matter-element. Evaluation matter-element are established by evaluation system of man-machine-environment system safe, aimed at a particular example, weight are determined by using the combination of AHP and entropy, finally comprehensive evaluation of man-machine-environment system safe is practised. Thus, this evaluation is feas...
