Abstract: Mine slope instability is a common geological disasters in mine,so,monitoring the waste dump is always the focus of the safety work in mine.Monitoring the displacement of waste dump cannot reflect the change trend of waste dump slope timely and completely.The GPS monitoring system not only reflect the state of equilibrium of surface displacement and stress of slope distinctly,but also conduct landslide warning by deep stress curve.Taking the northern waste dump in Zijin copper mine as an example,the monitoring points are set to monitor and analyze the displacement and stress.So,the good warning effect is obtained.

Key words: Waste dump, Monitoring the displacement, Monitoring the stress
