本文应用水文地质数值法(二维非稳定流里兹有限单元法)预报了车集井田矿井涌水量,根据本区的水文地质条件及设计部门的意见,把将来开采威胁较大的石炭系太原组上段灰岩含水层,作为本课题的预报层段,预报了—450、—600、—800米水平突水点的涌水量。此外,还对计算区的水文地质参数进行了优选,通过勘探工程揭露与邻区生产矿井验证说明计算结果是符合实际的,已作为设计的依据。计算中使用的计算机为美国产BCM一68K微型机,采用BASIC PLUS语言,解算方程组采用改进平方根(LDL~T)法。
According to the hydrogeological conditions in this area and the opinions of the design department, the paper puts forward that the future coal mining in Taiyuan, which is threatened by the exploitation in the future, is predicted by the hydrogeological numerical method (two-dimensional unsteady flow Leeds finite element method) As the limestone aquifer in the upper segment of the group, as the forecasted interval of this project, the inflow of water at water level of -450, -600 and -800 meters is forecasted. In addition, the hydrogeological parameters of the calculation area are also optimized. It is in accordance with the actual design that the results of exploration and mine demonstration in the neighboring areas should be exposed through exploration projects and has been used as the basis for design. The computer used in the calculation is a BCM-68K microcomputer manufactured in the United States, using the BASIC PLUS language and solving the equations using the improved square root (LDL-T) method.
