摘要
通过野外实地调查分析,得出了东川铜矿区泥石流特征。从地貌、地质构造、气候、水文和植被等矿区特殊的地质环境和矿山长期采矿、工程建设、废石尾矿排放及人类活动等人为因素两方面分析得出了矿区泥石流的形成原因,以便今后了解矿区泥石流形成机理,提高对泥石流的防治意识,从而达到防灾减灾目的。
In this paper,we study and analyzethe characteristics of debris flow in Dongchuan copper mining area by field survey and discuss the cause of debris flow from landform,geological structure,climate,hydrology,vegetation,and human factors such as a long-time exploiting,engineering activities,unreasonable engineering activities so as to understand the mechanism of forminig debris flow,raise people＇s awareness of preventing and harnessing the debris flow,and achieve the purpose of preventing and reducing the disaster of debris flow.
