摘要/Abstract

摘要： 戴家沟是一条潜在泥石流沟，流域面积约1．25×10m，泥石流物源主要为矿渣，储量约1．2×10m。利用x 衍射光谱分析了黏土矿物试样；根据黏土矿物的结构及物理特征，从微观的角度分析了泥石流的形成原因。分析表明：黏土矿物具有巨大的表面积和亲水性，它的存在会促进泥石流的形成。在对泥石流物源岩土特性、泥石流流量、流速和冲击力分析基础上，采用重力式拦渣坝和速流结构进行了T程治理。

关键词: 矿山泥石流, 矿物成分, X射线光谱分析法

Abstract: Daijiagou gully is a place of potential debris flow．with a flow-afected area of nearly 1．25×10m．The debris floWsource mainly is slag which is about 1．2 ×1 0。M． After site sampling and analyzing clay minerals with X-difraction spectruMmethod．According to the structure and physical characteristics of clay mineral，the reasons which induced debris floWwere analyzed froMthe microscopic point of view．The result shows that clay minerals which has immense surface and hydrophilicity could promote the formation of debris flow．Based on the analysis of source characteristics，discharge of debris flow，velocity and snatch force，gravity debris retaining daMand high-speed drainage structure were adopted to control the debris flow．

Key words: mine debris flow, mineral composition, X-ray spectroscopy analysis method
