| 摘 要： | 从宏观矿区、采区角度采用多因素综合分析技术预测,整体进行总体富水分区,然后再从微观巷道、工作面角度采用矿井瞬变电磁法探测局部富水情况,形成宏观预测、微观探测的"双测技术"体系。以赵庄二号井作为研究对象,综合分析了含水层厚度、岩性结构指数和构造分形维数对含水层富水性的影响,对以上3个因素标准化后,通过多因素分析法将该矿砂岩含水层的富水性分为强富水区:W≥0.5,中富水区:0.35

| Abstract: | Multi-factor comprehensive analysis technology is used to predict the overall water-rich partition from the perspective of macro mining area and mining area. Then, using the transient electromagnetic method of mine to detect local water-rich conditions from the perspective of micro-roadway and working face, macroscopic prediction and microscopic detection are formed a "double measurement technology" system. Taking Zhaozhuang No. 2 mine as the research object, the effects of aquifer thickness, lithological structure index and structural fractal dimension on the water-rich aquifer are comprehensively analyzed. After normalizing the above three factors, the mine is analyzed by multifactor analysis. The water-rich water content of sandstone aquifer is divided into: strong water-rich area:W≥0.5, medium-rich water area: 0.35
