Abstract: According to the destruction of tailings，mainly in order to monitor rainfall and seepage，based on wireless communication technique，and integrated with pluviometer，piezometer，data acquisition and transmission unit，a data acquisition system for tailings pond is established.By warning alarm，warning lights and warning SMS module，a wireless sound and light alarm device is set up，forming a pre-warning device system for tailings ponds.Based on network programming techniques and SQL Server 2005 database，the pre-warming software system for management and analysis of tailings monitoring information and data with the integration of “remote monitoring，communication，forecasting and application” was developed，which realized the remote management，visualization，data analysis and remote pre-warning” of monitored information and data.According to the field application，this system can quickly acquire and analyze the monitored data and precisely forecast the situations.It has important guiding meaning for the safe operation of the tailings.

Key words: Tailings pond, Wireless sensor networks, Real-time monitoring, Remote pre-warning system
