摘要
为明确高海拔地区冻融循环和降雨等外部因素对露天矿山边帮的影响规律,提升高海拔露天矿山对滑坡风险的认知及应对能力。基于新疆某铁矿低温高海拔地区的边坡合成孔径雷达(SAR)及气象监测,获取在时间序列下环境温度和降雨量与边坡雷达监测变形数据的对应规律,提出该矿山边坡变形的机理并研判边坡近期状态。研究结果表明:冻融循环作用产生的裂隙在后续频繁降雨的影响下产生的大量变形是影响该矿边坡稳定性的最不利因素,结合雷达监测数据为矿方提供合理建议,可为矿山的安全生产提供保障。
In order to clarify the influence of external factors such as freeze-thaw cycle and rainfall in high-altitude areas on the edge of open-pit mines,the awareness and response ability of high-altitude open-pit mines to landslide risks were improved.Based on slope synthetic aperture radar(SAR)and meteorological monitoring in a low-temperature and high-altitude area of an iron ore mine in Xinjiang Province,the corresponding laws of ambient temperature and rainfall and slope radar monitoring deformation data under time series were obtained,and the mechanism of slope deformation of the mine was proposed and the recent state of the slope was judged.The results show that the large amount of deformation of the cracks generated by the freeze-thaw cycle under the influence of subsequent frequent rainfall is the most unfavorable factor affecting the stability of the slope of the mine,and the combination of radar monitoring data provides reasonable suggestions for the mine,which can provide guarantee for the safe production of the mine.
