摘要：The cutting experiments with different drums (seven types of drums) and picks (eight types of picks) were done, which to acquire the empirical mathematic model of the cutting torque of the shearer drum. According to the existed research results, the structure of the empirical mathematic model of the cutting torque was formed, and regression analysis of the test date was performed to get the suitable date for empirical mathematic model solution by using BP neural network. Based on this, the unknown coefficients of the model were solved, and the empirical mathematic model was acquired, too. To verify the reliability of the empirical mathematic model, the five different experiments were done. The research results indicated that the error of the built empirical mathematic model was smaller than 10%, which satisfied the needs of engineer design.
