Application of fuzzy comprehensive evaluation method in coal mine "six systems"

A fuzzy comprehensive evaluation method was established by use of fuzzy mathematics theory. From acceptance standard of coal mine "six systems", an evaluation index system of coal mine "six systems" was built by the fuzzy comprehensive evaluation method. The evaluation index system is divided into a number of primary, secondary indicators and veto, and it uses analytic hierarchy process to determine weights of evaluated factors, so as to implement comprehensive evaluation of quality grade for coal mine "six systems". The actual application results verify feasibility of the method.
