摘　　要：研山铁矿露天矿水文地质条件复杂,上部为第四系土层,下部岩石结构破碎、稳定性差,且含鹅卵石层,因紧邻滦河新河,含水量较高,已经出现多个渗水点,并多次发生局部边坡片帮和滑坡现象。结合现场实际情况,对边坡渗水点位置进行梳理,通过对外汇水修建截水沟进行截水、对第四系含水层透水采取堵水及抽水、在局部边坡设置集渗排水设施等综合治水措施,有效解决采场边坡渗水,并实现采场内积水有组织排放。方案保证了采场作业人员和设备安全,确保采场正常生产,避免发生滑坡灾害。The hydrogeological conditions of the open-pit mine of Yanshan Iron Mine are complex.The upper part is the Quaternary soil layer,and the lower part of the rock structure is broken and poor sta⁃bility,and contains cobblestone layer.Due to the close proximity to the Xinhe River of Luanhe River and high water content,there have been multiple seepage points,and local slope spalling and landslide have occurred many times.Combined with the actual situation of the site,the location of the seepage point of the slope is sorted out.Through the construction of intercepting ditches for foreign exchange water,the water plugging and pumping of quaternary aquifer,and the setting of seepage collection and drainage facilities on local slopes,the seepage of stope slope is effectively solved,and the organized discharge of accumulated water in the stope is realized.The scheme ensures the safety of stope workers and equipment,ensures the normal production of stope and avoids landslide disasters.
