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.
