摘要
8^#煤轨道联巷布置在二叠系山西组下段的3^#、4^#煤层底板到石炭系上统太原组中段8^#、9^#煤层之上的煤系地层之中,受太原组L1~L5灰岩水水害的影响严重。通过对双柳矿水文地质特征及8^#煤轨道联巷探放水情况的研究及对水质化验资料的分析,得出影响该巷水质分析的因素,并通过分析查清该区域太灰水各含水层间、太灰水与奥灰水的水力联系并编制了双柳矿太灰水水位等值线图,为下一步采取有效的防治水措施提供了依据。
No. 8 coal roadway is arranged in No. 3 and No. 4 coal seam floor in the lower section of Permian Shanxi Formation to the coal-bearing strata above No. 8 and No. 9 coal seam of Taiyuan Formation in the upper Car- boniferous Taiyuan Formation. It is affected seriously by the L1 - L5 limestone hidden water disaster. Based on the hydrogeological characteristics of the Shuangliu mine and the exploration and analysis of the water quality of the No. 8 coal roadway, the factors of influencing the water quality analysis are obtained. By analyzing hydraulic connection a- mong limestone water aquifer, between limestone water and ordovician limestone water are verified. Shuangli limestone water level contour map is established. It provides the basis for effective water prevention and measures. u mine control
