摘　　要：露天矿山开采过程中会剥离大量的废土石,废土石集中堆放到排土场。排土场因水文条件酿成的滑坡事故约占矿山总事故的50%,合理的设置排土场排洪系统,是保证矿山安全生产的重要因素。截洪沟将上部汇水区域内的雨水拦截后,导入排土场两侧的水沟,预防雨水冲刷排土场,确保排土场安全。In the process of open-pit mining,a large amount of waste earth and stone will be stripped off and piled up in the dump.Landslide accidents caused by hydrologic conditions in dumps account for about 50%of total mine accidents.Reasonable setting of drainage system in a dump is an important factor to ensure the safety of mine production.Flood interception ditch intercepts rainwater in the upper catchment and lead it into the ditches on both sides of the dump to prevent the rainwater from washing the dump and ensure safety of the dump.
