| 摘 要： | 在大量统计资料的基础上,对矿山排土场滑坡破坏进行了深入细致的分析,提出排土场滑坡破坏存在排土场内部滑坡、沿地基接触面滑坡、因软弱地基底鼓引起滑坡三种形式。结合永平铜矿排土场滑坡、泥石流及降雨实测资料,分别研究了南部和西北部排土场10min和1h雨强与总实效雨量的关系,提出了泥石流产生的暴雨临界线,通过实测资料散点图及公式拟合,可较为可靠地预测排土场泥石流的发生。

| Abstract: | Based on the statistical data, intensive analysis was carried out on the slide of mining waste dump. Three types of landslide were proposed, which includes interior slide, slide along contact surface and slide caused by floor heave. According to the measured data of dump slide, debris flow, and measured precipitation of Yongping Copper Mine, relationship between the effective rainfall intensity in 10-min and 1hour and the effective rainfall, was studied about the south and northwest waste dump. Then the rainstorm critical line was put forward. Combined with measured data scatter diagram and fitted formula, the debris flow of waste dump can be predicted in a reliable probability. |

| Keywords: | waste dump debris flow forecast and prediction dump slide rainfall precipitation |
