| 摘 要： | 在滕县、兖州含煤盆地内,上侏罗统红层直接覆盖于二叠、石炭系煤系地层之上,在勘探时期曾被归为隔水层。本文通过现场资料分析和大量室内测试结果,系统研究了本区红层的化学成分和矿物组成、储水空间和分布特征及其红层地下水对煤矿开采的影响。作者得出下列结论:在岩性和构造适宜地段,红层中可以赋存较为丰富的地下水,他们既是许多煤矿的供水水源,又对煤矿的开采构成充水威胁,并通过采动裂隙引发突水事故。

| Abstract: | Upper Jurassic red bed,covering directly on coal-measure strata of Permian and Carboniferous System in Tengxiom-Yanzhou coal bearing Basin,was regarded as a aquifuge in exploration stage.In this paper a systematicalty study of chemical and mineralogical compositions of red beds,water-storing space and distribution pattern in red bed,and effect of groundwater on coal production is made by mean of analysis of exploration and laboratory data.Then the authors reach a conclusion that the red bed can store plentiful ground water in some suitable areas with lithologic and structural conditions due to development of pores、fissures and karst cavers.Groundwater in red bed is not only water supply for many mines,but can also threaten coal production as it is an important source for filling mine shaft and often bursting from mining-induced fissures in mine workings. |
