泥石流有自然泥石流和人工泥石流之分。矿山泥石流是人工泥石流的一种。所谓矿山泥石流,即指人们在矿山剥离或土石方工程(修建铁路、道路等)中,由于盲目排弃岩、土及其滑坡、塌方所导致的泥石流。矿山泥石流与自然泥石流一样,必须同时具有三个条件,即:①陡峻的地形坡度;②大量的固体物质;③丰富的水流(包括大气降水 Debris flow with natural debris flow and artificial debris flow points. Mud debris flow is a type of artificial debris flow. The so-called mine debris flow, that is, people in the mine stripping or earthwork (construction of railways, roads, etc.), due to blind abandonment of rock, soil and landslides, landslides caused by landslides. Like the natural debris flow, the mine debris flow must have three conditions at the same time: ① steep terrain gradient; ② a large amount of solid matter; ③ rich water flow (including atmospheric precipitation
