摘要: 在井下泥石流调查分析的基础上,采用专家问卷调查和层次分析法相结合的方法对井下泥石流形成影响因素进行了深入研究,建立了井下泥石流形成影响因素指标体系。研究表明,大气降雨量及其持续天数、黄土厚度及性质、地表塌陷、矿山开采、地表水人为排放等对井下泥石流的形成起着至关重要的作用,研究成果为井下泥石流发生危险度预测提供了理论依据。

Abstract: Based on the survey and analysis of underground debris flow,and using the combining method of expert-level questionnaire survey and the analytic hierarchy process,the factors of underground debris flow formation are researched,and the indicator system of influencing factors about the underground debris flow is established. Studies showed that the factors,such as rainfall and continuing days,soil thickness and its characters,surface subsidence,mining,surface water played the vital roles in the formation of underground debris flow,then providing a theoretical basis on forecasting the occurrence of underground debris flow.
