摘要: 为保证29采区安全顺利开采,通过对29采区底板进行疏水降压,揭示和验证了采区作为独立水文地质单元的封闭性特征|获取了底板主要含水层——太灰段的渗透系数等水文地质参数|利用非稳定流理论和井群干扰理论对采区底板的疏降效果进行预测。结果表明,通过合理布置钻孔对底板太灰水压疏降,效果显著,具有现实可行性。同时,对于改进车集煤矿底板防治水技术手段、降低防治水工程成本等均具有重要意义。

Abstract: Abstract:In order to ensure the safe and smooth mining of the 29 mining areas,the feasibility of the Taiyuan Formation limestone water drainage in panel 29 is studied;Through the water pumping and pressure releasing test on the bottom plate of the panel 29, the hydrogeological parameters such as the permeability coefficient of the main water-bearing section of the bottom plate are obtained; the well group disturbance theory and the unsteady flow theory are further used to predict the feasibility of floor drainage. The results show that the reasonable drilling arrangement and water release help lower the water table of the limestone aquifer, and the effect is remarkable. and it has practical feasibility. At the same time, it is of great significance to innovate the water control technology and reduce the cost of water control engineering.
