摘要
通过人工降雨模拟实验,对岚县葛铺煤矿堆土场,弃渣场及原状地貌耕地的径流量和泥沙量进行了系统的研究。结果表明,在降雨量相同的情况下,不同下垫面条件下的径流量与泥沙量的排序为:堆土场】弃渣场】耕地;随着降雨量和坡度的增大,各地类径流量和泥沙量也随之增大。并且针对实际情况,对该矿区未来的水土流失防治技术进行了探讨。
Runoff and sediment of soil accumulated place,residues place and cultivated land are studied through artificial rainfall simulation in LanXian GePu coal mine.The results show that the runoff and sediment volume is accumulated soil place>residues place>cultivated land under the same overland flow.The runoff and sediment volume increased with the increase of the overland flow and slope.And in light of actual conditions,the future of mining area of soil erosion control techniques is discussed.
