在神府—东胜矿区人为泥石流沟道广泛野外调查的基础上,分析了该区人为泥石流形成的固体物质补给特点:①矿区建设过程中(包括采煤、修路、采石、基建等)的弃土弃碴是主要补给源;②工程建设加大临空面,改变了沟口侵蚀基准面,由此而激发的重力崩塌及加速的沟床溯源侵蚀是潜在的补给来源;③人为活动导致环境破坏,加速的土壤侵蚀是泥石流细粒物质的主体补给源。
On the basis of extensive field investigation of man-made debris flow channel in Shenfu-Dongsheng mining area, the characteristics of solid material replenishment caused by artificial debris flow in this area are analyzed: ① During the construction of mining area (including coal mining, road construction, quarrying, infrastructure construction, etc.) Of the spoil is the main source of replenishment; (2) the construction of the project increases the freeboard surface and alters the erosion level of the Mizoguchi, which triggers the gravity collapse and the accelerated erosion of the gutter as a potential source of supply; (3) human activities Leading to environmental damage, accelerated soil erosion is the main supply of debris flow debris.
