牛首山东麓矿山泥石流形成机理分析

The analysis of mine debris flow formation mechanism in Eastern Niushou Mountain

为了科学防范泥石流隐患,以牛首山东麓马车沟泥石流为例,分析了其形成环境和发育特征,以及形成机理;进行了危险度模糊评价,针对性地提出了防治措施。结果表明,牛首山东麓以矿山型泥石流为主,对前缘的高速公路构成威胁,相关部门的管理要严格遵守"以防为主,防治结合"的原则。

The mine debris flow in Eastern Niushou Mountain has posed a threat to highways and other infrastructures which located near the mountain front. In order to prevent debris flow hazard, took Mache ditch debris flow in Niushou Mountain as an example, this paper generally analyzed the formation environment and development characteristics, researched the formation mechanism, made the risk fuzzy evaluation, and specifically proposed the control measures. The results show that the geological disaster in Eastern Niushou Mountain are mostly presented in type of the mine debris flow, relevant departments should strictly implement the principle of ＂prevention based, prevention and control combined＂.
