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。
In the Tengxian and Yanzhou coal-bearing basins, the Upper Jurassic red beds directly overlie Permian and Carboniferous coal measures and were classified as aquitards during exploration. In this paper, through the field data analysis and a large number of indoor test results, the chemical composition and mineral composition, water storage space and distribution characteristics of the red beds and the impact of the red groundwater on the coal mining were systematically studied. The authors conclude that abundant groundwater can be found in the red beds at lithologically and structurally appropriate locations, both as a source of water for many coal mines and as a threat of water flooding to the mines and as a result, Water accident.
