摘　　要：康家湾矿Ⅲ-1矿体为一赋存在含水层下的矿体,为确保其回采的安全,采用RFPA2D对不同结构参数采场导水裂隙带的发育高度进行了模拟,建立了采场导水裂隙带发育高度预测的ANFIS模型,对康家湾矿Ⅲ-1矿体14#采场导水裂隙带的发育高度进行了预测,同时还对其进行了实测.研究结果表明:在矿岩力学参数不变的条件下,矿房跨度、间柱跨度及采空区高度是影响采场导水裂隙带发育高度的关键因素;所建立的采场导水裂隙带发育高度预测的ANFIS模型的拟合精度和预测精度分别达95%和98%以上;采用该模型预测的康家湾矿Ⅲ-1矿体14#采场导水裂隙带的发育高度与实测结果吻合良好.The Ⅲ-1 ore body in Kangjiawan mine lies beneath an aquifer.In order to mine the ore body safety,this paper firstly used RFPA2D for simulating the heights of the transmissive fractured belts of mining stopes with different structural parameters.Then,the simulating results were used for establishing the ANFIS（Adaptive Neuro-Fuzzy Inference System） model for predicting the height of the transmissive fractured belt of a mining stope.Finally,the ANFIS model was used for predicting the height of the transmissive fractured belt of 14^# mining stope for Ⅲ-1 ore body and the practical height was measured.The results show that,with the mechanical parameters fixed,room span,interval pillar span and stope height are the key parameters influencing the height of the transmissive fractured belt of a mining stope,that the accuracies of the fitting and predicting results by the established ANFIS model amount to 95% and 98%,respectively,and that the predicted height of the transmissive fractured belt of 14^# mining stope for Ⅲ-1 ore body by the established ANFIS model and the measured height are in good agreement.
