一、前言我国发生矿山泥石流的实例很多,它不仅会给矿山生产带来严重危害,并经常堵塞河道、淤埋农田、毁坏工业、民用、水利工程设施,给国民经济造成巨大的损失,因此对矿山泥石流的研究,已引起环境学界和矿山地质工作者的关注。但我国目前对尚未开发的矿山进行泥石流能预测评价,尚无前例,更无成熟的方法和模式可供借鉴。我们在A矿环境影响评价中,根据当地的自然环境特点和矿山设计资料,通过类比法和水力计算等,对开发后的矿山泥石流进行了定性预测,但限于水平,它只能算做一种尝试。二、发生泥石流的因素
I. INTRODUCTION There are many examples of mine debris flow in our country. It not only brings serious harm to the mine production, but also often blocks rivers, silting farmland, destroying industrial, civil and hydraulic engineering facilities, causing huge losses to the national economy. Therefore, The study of mine debris flow has aroused the attention of environmental scholars and mine geologists. However, at present, there is no precedent or more mature methods and models for the prediction and evaluation of debris flows in the mines that have not yet been developed. In the environmental impact assessment of Mine A, we qualitatively predict the developed mine debris flow according to the characteristics of the natural environment and the design of the mine, through analogy and hydraulic calculation, but only to a certain extent try. Second, the occurrence of debris flow factors
