摘要
为了再现采动对主要充水含水层地下水流场的影响程度及其控制机制,在系统分析任楼煤矿地质与水文地质条件的基础上,采用FEFLOW软件建立了研究区地下水系统概念模型和数学模型及相应的地下水系统数值模型,合理开展了采动影响下四含、煤系、太灰与奥灰4个主要充水含水层近期渗流场特征的数值模拟。研究结果表明:从平面上,四含在研究区东部出现一低水位分布区,煤系在采动影响范围内典型断层局部附近渗流异常;从空间上,煤系在采动影响区垂向水位等值线发生偏转并与含水层顶底板近于平行,四含与煤系之间的隔水层水位等值线也近于平行,但在采动影响区内平行等值线密度最大;太灰与奥灰地下水流从平面与空间层面上均显示原来的运行状态;近期采动对任楼煤矿四含与煤系2个含水层影响最为显著。
In order to reproduce influence degree and control mechanism of mining disturbance to main discharge aquifers, numerical simulation of recent seepage field characteristics of the fourth aquifer of the Quaternary, the coal measures aquifer, the Taiyuan formation limestone aquifer and the Ordovi- clan limestone aquifer is carried out with the help of FEFLOW software after establishing conceptual model, mathematical model and corresponding numerical model in the groundwater system based on the systematic analysis of Renlou Mine^s geological and hydrogeological conditions. By plane analy- sis, the fourth aquifer of the Quaternary shows a low water level distribution zone in the eastern part of the mine and the seepage is unconventional near typical faults in mining disturbance area in the coal measures aquifer. By space analysis, vertical water level isolines in mining disturbance area in the coal measures aquifer show deflexion and nearly parallel to roof and floor of the aquifer, and the water lev- el isolines in the aquifuge between the fourth aquifer of the Quaternary and the coal measures aquifer are also nearly parallel, but those parallel isolines become dense in mining disturbance area. The groundwater flow of the Taiyuan formation limestone aquifer and the Ordovician limestone aquifer is in a former way by plane and space analysis. Therefore, the fourth aquifer of the Quaternary and the coal measures aquifer in Renlou Mine are observably influenced by mining disturbance recently.
