摘要
覆岩分类是经验类比法预测导水裂隙带高度的基础，应用模糊数学ｍ相分类法对煤层顶板物理力学性质指标进行处理，寻求煤层顶板对岩性“软”“硬”的隶属函数，建立模糊关系矩阵，进行煤层顶板类别的综合判别，并将其结果用于确定计算导水裂隙带高度经验公式的系数值。这一方法可以在很大程度上消除人为因素对覆岩分类的影响，使预测的导水裂隙带高度更符合实际情况。
The classification of overburden strata is a basis of predicting the height of water conducted zone with empirical analogy.This paper applies the m phase classification to the fuzzy processing of the coal seam roof,searches for the subordinate function between the rock native's “softness”and “hardness”,builds the fuzzy relation matrix,makes a synthetical judgement of the roof,and uses the results to determine the coefficient value of the empirical formula which is used to calculate the height of water conducted zone.By this method,the man made factors can be eliminated in great extent,and the height can be predicted reasonably.
