摘　　要：根据朝阳露天煤矿的实际地质条件,分析了露天矿受内排土场边坡位移影响的采剥、疏干排水相关问题;着重阐述了横采内排技术方案以及采场排水方法。结果表明:横采内排工艺在采场南北推进转向东西推进过程中,有效实现了超前内排,挖潜了有效的内排空间,为采剥接续稳定创造了良好的条件;通过采场排水方法在东端帮东侧新建集水坑,并与毛石导水盲沟有效结合,实现了采场有序排水。According to the actual geological conditions of Chaoyang open-pit coal mine,the related problems of stripping,dewatering and drainage affected by the slope displacement of the inner dump in the open-pit coal mine are analyzed;The technical scheme of internal drainage in horizontal mining and the method of stope drainage are emphatically expounded.The results show that in the process of moving the stope from north to south to East and West,the horizontal mining internal drainage technology has effectively realized advanced internal drainage,tapped the potential of effective internal drainage space,and created good conditions for the continuous and stable mining and stripping;The drainage method of the stope realizes the orderly drainage of the stope by building a new sump on the east side of the east end wall and effectively combining it with the rubble diversion blind ditch.
