摘　　要：矿山采用自然崩落采矿法开采时,在物源、水源、地质等因素综合影响下易出现井下泥石流灾害。为对高原地区某铜矿井下泥石流进行预防和治理,通过分析降雨—造浆—地表塌陷—通道诱发的井下泥石流灾害链,建立了包含5个一级指标,22个二级指标的风险评估指标体系。首先收集领域专家对指标的重要性评分结果;然后利用熵权法、层次分析法组合计算评价指标权重,通过物元可拓模型评价井下泥石流风险等级及各评价指标风险等级;最后结合各指标的权重均值与物元可拓模型指标评估结果,对高权重、高风险指标进行重点防治。结果表明,该矿山井下泥石流风险等级为较高,其中降雨量、冰碛物块度、应急处置等指标风险程度与权重排名较高,通过提出的防治措施可以降低其风险程度,从而减少井下泥石流的发生,为该矿山井下泥石流防治提供了有效指导。When the natural caving mining method is used for mining,the underground debris flow disaster is prone to occur under the comprehensive influence of material source,water source,geology and other factors.In order to prevent and control the underground debris flow of a copper mine in the plateau area,analyzing the underground debris flow disaster chain induced by rainfall-pulp-surface collapse-channel,a risk assessment index system including 5 first-level indicators and 22 second-level indicators was established.Firstly,the importance score results of the indicators were collected from the experts in the field,and then the weights of the evaluation indicators were calculated by the combination of entropy weight method and analytic hierarchy process.The risk level of underground debris flow and the risk level of each evaluation indicators were evaluated by matter-element extension model.Finally,combined with the weight mean of each indicator and the evaluation results of the matter-element extension model,the key prevention and control of high-weight and high-risk indicators were carried out.The results show that the risk level of underground debris flow in the mine is high,among which the risk degree and weights of rainfall,moraine fragmentation,emergency disposal are ranked a bit high.The proposed control measures can reduce the risk degree,thereby reducing the occurrence of underground debris flow,and providing effective guidance for the prevention and control of underground debris flow in the mine.
