Abstract:

Based on the engineering background of Shi rengou iron mine， according  to the practical  condition，using multi-stage fuzzy synthetic judgement theory，this paper makes a two-stage fuzzy synthetic judgement model of the stability of mine gob area with 15 factors.The fuzzy evaluation matrix is made using expert evaluation method and three-phase linear membership function method to evaluate the qualitative and quantitative factors.The weight of factors are determined using AHP，then a weight matrix is made.The concourse are then calculated together with the evaluating matrix to complete the synthetic evaluation of gob area stability variable.The results show that the evaluation results can accurately reflect the stability of mine gob area.This is a effective method to analyze the stability of mine gob area.

Key words: AHP, fuzzy synthetic judgement, stability evaluation, goaf
