Abstract


In this dissertation, the MSARMA stability computation model and GIS3D visualization engineering geology model of opencast and underground mining are constructed, through the research and analysis of Antaibao open pit mine engineering geological characteristics. Slope stability calculation of opencast and underground mining under the natural conditions, rainfall, earthquake, rainfall and earthquake coupling conditions are carried out in sequence, according to the slope stability coefficient from calculation, based on the GIS operating platform,3D visualization slope stability partition is researched, which can show the slope stability situation under the complicated conditions visually and stereo. The computational analysis of slope stability show that the stability of Antaibao open pit slope under the natural condition is not enough. Therefore, the slope stability remote monitoring system with the integration of monitoring, early warning, reinforcement, prevention and treatment, is applied for the monitoring and control of opencast and underground mining slope, through the research of3D visualization slope stability partition under the monitoring and reinforcement conditions, it is proved that the slope stability promotes obviously after the monitoring and reinforcement system application, which can meet the safety requirement.
