摘要
为了较全面地考虑煤层顶板导水裂隙带发育高度的影响因素,在结合大量生产实践的基础上,分别从开采厚度、开采深度、工作面斜长、岩石抗压强度、岩层组合特征等因素进行分析,对各影响因素构造了影响指标并进行量化,采用层次分析法研究影响因素的权重,采用模糊聚类分析法对工作面的裂隙带发育高度进行聚类。10个工作面的数据验证结果表明:开采厚度是影响导水裂隙带发育高度的主要因素之一,其他几个因素也是影响导水裂隙带发育的主要因素。研究所得结果与经验值和实测值都基本相似,说明本文选取方法是合理的,为煤矿预测煤层顶板裂隙带发育高度提供了一种新的方法。
Based on the analysis of the factors influencing the height of water flowing fractured zone of roof, mining thickness, mining depth, and working face length, compressive strength of rock and characteristics of rock assemblages have been studied and the corresponding influence indexes have been quantified. Then the weight of the factors has been studied through the analytic hierarchy process and the height of fractured zone has been clustered by the fuzzy clustering analysis method. The result of the study of 10 working face data shows that the mining height is just one of the main factors influencing the height of water flowing fractured zone, with several other factors having an effect on it as well. The research results basically equal the empirical values and measured values. So it is a reasonable study method through which the height of water flowing fractured zone of coal seam roof can be predicted for coal mine.
