对含水层的富水性进行评价是确定煤层底板是否突水的重要前提,选取构造裂隙发育程度、含水层厚度、脆性岩与塑性岩厚度比、钻孔涌水量共4个因素进行分析,利用AHP模型确定各因素的权重。利用SURFER的信息融合及数据处理功能,将归一化处理后的各主控因素进行分析,建立良庄井田15煤层富水性评价模型,最终对奥灰含水层进行富水性分区。
The assessment of water-rich aquifer is an important prerequisite to determine whether the coal floor water inrush. According to four factors including structural fracture development, thickness of aquifer, thickness ratio of brittle rock and plastic rock, The model determines the weight of each factor. By using SURFER’s information fusion and data processing functions, the normalized main control factors are analyzed to establish the evaluation model of water-rich in coal seam 15 of Liangzhuang Minefield. Finally, the water-rich zoning of Ordovician gray aquifer is carried out.
