Study on Causes and Control Measures of Daijiagou Debris Flow in
Tianfu Mine Area

Abstract

Abstract: Mine debris flow whose main material is slag is one of the most serious environmental disaster problems in the exploitation of mineral resources． It happens frequently and abruptly． The density is large，and its process is monotony． It also changes with the accumulation of solid． According to Daijiagou debris flow in Tianfu mine area，the causes of the debris flow are analyzed and it is concluded that steep terrain，abundance of materials，a large number of clay minerals in slag and high intensity rainfall create conditions for the formation of debris flow． Based on the analysis of the basic parameters of debris flow，preventive measures are put forward，which offer references for the similar projects．

Key words: mine debris flow, causes analysis, design of prevention engineering, Dai Jiagou

摘要： 矿山泥石流是矿产资源开发过程中出现的一个重大环境灾害问题。其物源以矿渣为主，具有常发性、突发性、密度大、过程变化单调、随固体物质累积量的变化而变化等特点。针对天府矿区戴家沟泥石流，分析了其形成原因，得出: 陡峭的地形、丰富的物源、矿渣中大量的黏土矿物以及高强度的降雨为泥石流的形成创造了条件。在对泥石流基本参数的分析基础上，提出了防治措施，为相应工程提供了借鉴。
