Abstract: Due to the complex geological conditions, large amount of water yield, especially in the mining process, different scale slide and collapse had occurred many times in non-working slope of Shengli Open-pit Coal Mine, it affected the safety production. In addition to the conventional methods of slope treatment, in order to safety production, Shengli Open-pit Coal Mine had introduced the advanced IBIS-M radar displacement monitoring system to carry out real-time forecasting and early warning for slope, it improved the risk management of slope stability, and provided technical support for safety production.
