Abstract:Slope instability and failure are significant risks in open-pit mining. As a means of feedback on deformation information and early warning of slope failure, in-situ monitoring is of great significance for predicting slope safety risks. Although slope monitoring technology has made significant progress in recent years, slope monitoring design still faces some bottlenecks, such as reasonable matching of monitoring systems and difficulties in determining warning thresholds. Determine the content of slope monitoring according to relevant regulations for non-coal mines; Combining the mainstream “air sky ground” integrated monitoring technology of multi-source and multi-site safety monitoring for open-pit mine slopes, select safe and economical monitoring methods; Based on some actual monitoring cases of open-pit mining landslides in recent years, the early-warning threshold of slope monitoring design is given by using the four level early-warning system. The research starts from all aspects of slope monitoring and forms a complete set of design methods for open-pit mining slope safety monitoring based on multi-source data fusion.
