Abstract: Tailings displacement, saturation line and other security data are usually observed by men. These artificial observations are so insufficient and not accurate enough, which can not meet the requirement of safety management. According to the specific conditions of tailings ponds in Guangdong Yunfu pyrite mine, the automatic monitoring system was designed and installed. Through a trial operation and an actual observation, the system was operating normally, where each indicator can meet the requirements of relevant specifications and construction units.

Key words: Tailings pond, Automation, Monitoring, System
