| 摘 要： | 针对近年来采用崩落法开采的金属矿山井下泥石流频发，危害程度越来越严重的实际情况，以程潮铁矿井下泥石流发生的过程为工程背景，建立由矿石层、覆盖层、隔水层和泥石流层组成的数值计算模型，采用颗粒流(PFC3D)数值模拟软件对泥石流发生的动态过程进行研究，初步揭示了井下泥石流发生的动态演化过程及作用机理，总结出井下泥石流形成的力学实质和应采取的防治措施。

| Abstract: | In view of the increasingly more serious hazard due to the frequent underground mud-rock slides in metallic mines where caving mining method is adopted, with the process of underground mud-rock slide in Chengchao Iron Mine as the engineering background, a numerical calculation model is built, which composed of ore layer, overlaying layer, water partition layer and mud-rock slide layer.PFC3D numerical simulation software is used in the study of the dynamic process of mud-rock slide.The dynamic evolution process and mechanism of underground mud-rock slide is preliminarily revealed and its mechanical essentials and prevention and control measures that should be taken are summarized. |
