Optimizing technological parameters of fully mechanized with sublevel caving face by numerical simulation;

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.

In a word ,it is feasible that the fully mechanized caving technology uesd in the gas outburst coal seam only that effective predrainage before mining and capable measures during mining.
