Abstract: Aiming at solving the shortage of method in select the model of coal and gas simultaneous mining, the new idea of fuzzy analytic hierarchy process, which is designed to select the model of coal and gas simultaneous, Base on the basic principles of fuzzy analytic hierarchy process, 5 factors which influence the model selection such as geological factor, safety factor, technical factor, resource recover, economic benefits are confirmed, as well as 21 sub-factors, according to Coal 3 in chengzhuang mine. What’s more, the weights of the factors are determined by using FAHP . The selection of coal and gas simultaneous models in chengzhuang Mine are based on fuzzy comprehensive evaluation, the results show that simultaneous drainage of ground and mine in single seam is the best selection.

Key words: Gassy mine, model of coal and gas simultaneous, fuzzy analytic hierarchy process
