Abstract:In this paper the analytic hierarchy process was used to determine the factor weight of three kinds of typical caving heights of“low, medium and high” through the analysis of the main factors influencing the caving height of the overlying strata. A T-S fuzzy system was obtained according to the fuzzy partition of the discourse universe of various factors and a new T-S prediction model for the caving height of the overlying strata in the fully mechanized working face was established. With this model, the caving heights of the overlying strata in the fully mechanized working faces in Zhenchengdi, Wangzhuang and Duerping mines were calculated, the calculated results were respectively 16. 463 3, 18. 6887 and 16. 463 7 m, and the relative errors were respectively 0. 88%, 3. 42% and 8. 31%, which indicated that this prediction model has higher precision.
