本文以伊敏露天煤矿排土场为研究对象,对露天煤矿的3个排土场坡面(内排土场、沿帮排土场、西排土场)的侵蚀沟、地表糙度、容重、植被进行详细的调查,在一定的条件下对比分析各排土场的侵蚀状况和恢复情况。实验结果表明:伊敏露天煤矿排土场坡面侵蚀较为严重,排土场的水土流失(水蚀)主要受容重、地表糙度、植被覆盖度和植被类型4个因素影响,且植被覆盖度、植被类型等可变因子对排土场坡面水土流失影响程度最为明显。
In this paper, the Yimin opencast coal mine dump is taken as the research object. The erosion ditch, surface roughness, bulk density of three dump sites (inner dump, coastal dump and west dump) , Vegetation, a detailed survey, under certain conditions, comparative analysis of the drainage site of the erosion and recovery. The experimental results show that the surface erosion of the dump in Yimin opencast coal mine is more serious. The soil erosion (water erosion) in the dump is mainly affected by the factors of bulk density, surface roughness, vegetation coverage and vegetation types. The vegetation coverage, Variations such as vegetation types have the most obvious influence on soil erosion on the slope of the dumping site.
