井下泥石流物理模拟研究

通过对金山店铁矿井下泥石流的调查分析,按比例建造物理实验模型并在每个分层放置一定数量的标记颗粒,以连续出矿的方式来模拟井下泥石流的发生,进而推测其成因以及形成过程,与此同时记录出矿时标记颗粒位置的变化情况,借此来观察泥石流发生的影响范围。然后利用Surfer软件来粗略的绘制出井下泥石流发生时不同分层的黄土渗入界限,为泥石流的预警提供一定的依据。

Research on physical simulation of underground debris flow

Through the investigation and analysis of the underground debris flow in Jinshandian Iron Mine,a simulation model of physical experiment is built in proportion,and some marked particles are placed in every layer.In order to simulate the underground debris flow and conjecture its cause and formation process,the continuous drawing is adopted,at the same time the underground debris flow’s range of influence can be observed by recording the position changes of the marked particles.And then Surfer software can roughly draw the loess ’s infiltration boundary in every layer,and this can provide basis for the early warning of the underground debris flow.
