摘　　要：为了有效评价井田构造复杂程度,提出了基于层次分析法(AHP)-系统聚类分析(HCA)的方法。以黄河北煤田赵官矿井为例,在充分研究矿井构造发育规律的基础上,根据矿井实际发育情况,选取断层分维值、断层强度指数、褶皱分维值和岩浆岩复合影响指数4个定量评价指标,对井田内断层、褶皱、岩浆岩的发育及分布情况进行了定量化研究和评价。利用层次分析法构建井田构造复杂程度评价指标体系,确定了4个定量评价指标的影响权重分别为0.181、0.364、0.182和0.273。在此基础上,运用系统聚类分析方法,对井田地质构造复杂程度进行了分析研究,得到构造复杂程度简单、中等、复杂3类等级的分区评价图。本研究评价结果旨在能对矿井安全高效生产提供有效指导。To effectively evaluate the structure complexity of mine field, a method based on analytical hierarchy process （AHP） and hierarchical cluster analysis （HCA） was proposed. On the basis of extensive analyses of geological tectonic characteristics in Zhaoguan mine field, we carried out quantitative study and evaluation on the fault, fold, and magmatic rock development and dis- tribution in coal seam by selecting fault fractal dimension, fault intensity index, fold fractal dimension, and magmatic rock com- pound impact index as the evaluation indices. The weights of the above four parameters were determined by analytical hierarchy process, which are 0. 181, 0. 364, 0. 182 and 0. 273 respectively. And then the hierarchical cluster analysis method was applied in the forecast of the geological structure, and three structural subregions which correspond to simple, medium, and complicated grades were obtained. The results aim at providing more effective guidance to mine safety and high efficiency production.
