摘要: 由于矿区采矿爆破扰动的影响,使采场下帮边坡370 m以下平台未能按照设计要求靠帮,压覆高品位铁矿石近千万吨,给矿山造成重大经济损失。通过对南芬露天铁矿滑坡区域的长期监测资料进行分析和总结,提出依据地表位移-降雨量-时间曲线预报滑坡的方法,并在实践中得到证明,为下方矿石回采提供了安全保障。

Abstract: From the influence of mining blasting at mining area,platform below stope heading side slope 370m could not meet desigh request along end slope,nearly ten million tons of high grade iron ore were covered,which caused heavy economic losses to mine.Through analysis and summary of long-term monitoring data of landslide area of Nanfen open pit iron ore,landslide prediction method which according to surface displacement,rainfall and time curve was proposed and proved in the practice,provided safety guarantee for inferior ore mining.
