Slope prestressed anchor cable remote monitoring system in Liaoning Haizhou open-pit mine

With the closure of Haizhou open-pit mine,the rock mass structure is weakening and the supporting force of surrounding rock becoming smaller,the slope of Haizhou open-pit mine is unstable and has potential risks for large scale landslides.Based on the engineering geological condition,the slope shape,the steady-state and monitoring purpose of Haizhou open-pit mine,research and develop the slope prestressed anchor cable remote monitoring system in Liaoning Haizhou open-pit mine.The GPRS long range wireless transmission technology was used to remote initiative monitoring rock stress of slope for obtaining the characteristics of rock deformation and slip information,It can monitor the slope anchor cable stress all-weather and it is suitable for medium-and long-term slope monitoring as it power supplied by solar energy.According to the field application of the slope monitoring and the slope stability analysis in Haizhou open-pit mine,the system was proved to monitoring the slope stability in real time.It has important significance to control the slope landslide.
