摘要: 以抚顺西露天矿为研究区,利用GMS (groundwater modeling system)数值模拟软件在分析矿区及其周边区域地质及水文地质条件的基础上,针对地层岩性和地质构造特点,建立数学模型;结合工作区地质勘探资料及对充水因素的分析,建立水文地质模型,对涌水量作出预测,提出平衡状态时排水井的布置方案。结果表明:根据矿坑的地形特点分别在南北两侧安置5口深度为100 m,长度为100 m,排水量为10~20 m3/d的水平井,并且在模拟区矿坑最低处按照100 m的间距安置4口深70~100 m,排水量为20 m3/d的竖井时,矿坑中不会有水溢出。Abstract: In this paper, a mathematical model was set up, taking the Fushun West Open-pit mine as the research area, using the GMS (groundwater modeling system) numerical simulation software, based on the analysis of the mining area and its surrounding area, geological and hydrogeological conditions, as well as the characteristics of the formation lithology and geological structure. Based on the geological exploration data of the working area and the analysis of water filling factors, a hydrogeological model was established to predict the water inflow, and the layout scheme of drainage well in equilibrium state was put forward. The results showed that according to the topographic characteristics of the mine, when five horizontal wells with depth of 100 m, length of 100 m and displacement volume of 10~20 m3/d were placed on the north and south sides of the mine, and four shafts with depth of 70~100 m and displacement volume of 20 m3/d were placed at the bottom of the mine according to the spacing of 100 m in the simulation area, no water would overflow from the mine.
