AHP-Fuzzy optimization of structural parameters in sublevel openstope succedent filling method

In allusion to the fuzzy and uncertain information of sublevel openstope succedent filling method in practical engineering,some factors such as mining safety,economy and technology were taken into account and scenario optimization of the corresponding synthetic evaluation system was established by analytic hierarchy process(AHP).Then,the fuzzy mathematics method was also applied to optimize each scheme parameter and assess the weight of quantitative and qualitative indexes.Finally,optimal scheme parameters were obtained by the fuzzy matrix,thereby leading to mining safety and high efficiency mining.
