Outline
Based on the geological conditions and surrounding environmental survey results of the open-pit mine waste dump slope deformation monitoring, using the Beidou high-precision positioning technology, five Beidou displacement monitoring points were set up on the 1590, 1586 and 1580 platform slopes of the waste dump, and the real-time monitoring of the slope deformation of the waste dump was achieved. The statistical analysis of deformation monitoring data for 10 consecutive months shows that the construction of the waste dump has led to the vertical deformation of the slope at each monitoring point. The vertical deformation of the 1590 platform slope is significant, with the average monthly cumulant of deformation about 6.0 mm, and the average monthly cumulant of the vertical deformation of other platform slopes is less than 3.0 mm. No acceleration or step change of deformation has occurred at each monitoring point, and the waste dump slope is still in a stable period. The application of Beidou satellite system in displacement monitoring of waste dump provides automated monitoring methods and raw monitoring data for slope deformation trend prediction and safety warning, ensuring the safety of open-pit mine waste dump stacking operations.
