摘要
叙述了工程概况,分析了影响砂岩含水层富水性的3个主要因素,并综合各个影响煤层顶板砂岩富水性因子,将煤层顶板岩层的岩性结构指数标准化,进而对顶板砂岩含水层富水性进行了预测。研究结果表明,岩性结构标准化计算得到1#煤顶板富水性分区界限为0.7和0.2,岩性结构指数越大,富水性等级越高。
This paper described the general situation of the engineering, analyzed three main factors that affected the water yield property of the sandstone aquifers, standardized the lithologic structure index of the roof strata of the coal seam with regard to these factors and then predicted the water yield property of the sandstone aquifers of the roof. The results showed that the boundary of water yield property was 0.7 and 0.2 of 1#coal roof though the standardization calculation of lithology structure, and the larger the lithologic structure index was, the higher the water yield property grade was.
