Research on the fuzzy clustering of comprehensive support working resistance

On the basis of samples of top-caving fully mechanized support strength measured, combined with other factors of the mining face,the samples are analyzed by fuzzy cluster in fuzzy math.Then the regression analysis is used and mathematical model is established. That the mathematical model to establish comprehensive caving face support and strength to quantify the impact of factors, for the production of fully mechanized mining face practice of estimating the strength of support provided a scientific theory.
