康家湾矿含水层下采场导水裂隙带发育高度预测
Prediction of the Height of the Transmissive Fractured Belt of A Mining Stope Under Aquifer in Kangjiawan Mine
摘要
Abstract
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.关键词
