Fully mechanized sub-level caving face is a complicated non-linear system, and the selection of equipment and technological parameters for coal drawing and the forecast of technical-economic indexes of the face are complicated non-linear problems which are difficult to solve with traditional mathematical method. A neural network model is established to predict face production, efficiency and recovery rate, to select shearer and powered supports and to optimize coal drawing method and interval. The results of actual application indicate that the model is reliable and precise and has larger practical value.
