摘要
针对金属矿山泥石流发育与潜势度的关系,对影响矿山泥石流发育的主要因素进行综合分析,确定其隶属函数,采用层次分析法确定各影响因素的权重系数,并应用模糊数学理论的方法来判定金属矿山泥石流发育潜势度的级别,通过确定潜势度的级别对矿区内地质灾害进行定量化评价确定灾害等级,为金属矿山泥石流地质灾害的防治提供依据。
To the relationship of debris flow development and potentiality in metal mine, the paper analyses the main influential factors to debrits flow, determines its memberhip functions, fixes the weight indexes, and divides the potentiality grade for debrits flow development. Through grade division, it conducts quantity evaluation to make sure the hazard level, and then provides the basis for prevention and control of debrits flow in metal mine.
