【 摘 要 】

In a coal mine, the 15# coal seam is first exploited, and the 6# coal above the 15# coal is not exploited, so the 6# coal seam above the 15# coal belongs to the kicking mining. It is necessary to judge the feasibility of the coal seam. On the basis of the analysis of the coal seam occurrence conditions in this mine, the factors affecting the kicking of 6# coal seam are analysed, and the feasibility of the 6# coal bed kicking feasibility is preliminarily judged by using the ratio discrimination method, the "three band" discriminant method, the surrounding rock balance discrimination theory and the mathematical statistics analysis method, and the fuzzy evaluation algorithm is used for the 6# mining. The feasibility of the implementation of coal mining is further demonstrated. The analysis results show that it is feasible to implement comprehensive mechanized coal mining in 6# coal seam.
