摘　　要：南方露天煤矿地下水丰富、降雨量大,应用排土场暗涵工程的煤矿较多,文章详细介绍了露天煤矿排土场常用的暗涵形式并分析了各种暗涵形式的适用条件,确定了暗涵的外力计算、暗涵结构、断面选取的过程,并给出了暗涵反滤层和泄水孔的做法。Open pit mines in the southern China are rich in underground water because of the large precipitation, socovered culverts are widely applied. The forms of covered culverts and the application condition in the waste dump wereanalyzed. The external force calculation, covered culverts structure and the selection of cross section were introduced,and the loaded filter and weep hole design of was covered culverts was given.

关 键 词：露天矿排土场 暗涵结构 暗涵形式 暗涵反滤层 暗涵泄水孔
