| 摘 要： | 针对平朔井工三矿太原组9#煤层开采受顶板砂岩含水层水影响严重的问题,分析了影响煤层顶板砂岩富水性的主要因素;根据矿井9#煤层水文地质特征,结合单因素分析,采用模糊综合评判方法,以砂岩厚度、脆塑性岩厚度比值、构造复杂程度为评价指标,对9#煤层顶板的砂岩裂隙含水层富水性进行了分级分区。后续掘进工程表明,分区结果与生产实际情况有良好的吻合性。

| Abstract: | Aimed at the mining of No.9 coal seam of Taiyuan formation in No.3 coal mine seriously influenced by water in roof sandstone,the key factors affecting the enrichment of water in roof sandstone of coal seam were analyzed.According to the hydrogeological characteristics of No.9 coal seam,together with the single factor analysis,the water enrichment in the fracture aquifer of roof sandstone in No.9 coal seam was graded and divided by using the fuzzy comprehensive evaluation method in terms of sandstone thickness,thickness ratio of brittle rock to plastic rock and structural complexity.The subsequent excavating project showed that the division result has a good coincidence with the practical production. |
