Abstract: Tailing pond is an artificial debris flow hazard with high potential energy，so it is very important to monitor its stability to prevent the occurrence of dam breaking.Based on the GSM/GPRS communication network platform，the wireless remote transmission technology of monitoring data，which includes deep displacement and surface displacement of tailing dam，phreatic line，seepage pressure，water level of tailing pond，rainfall capacity，beach length and safety altitude difference，were researched with new-type monitoring technology and methods.Round-the-clock，automatic，remote monitoring of the stability of tailing dam was realized.High precision on-line monitoring system of tailings stability with the function of monitoring data timing acquisition and real-time transmission was constructed.This on-line monitoring system provided an effective technical mean to obtain the dynamic evolution information in the process of tailing pond operation.
