Stability of Dip Bedded Soft Rock Slope in Surface Coal Mines Based on Displacement Monitoring

摘要

Displacement monitoring technology is widely used in slope engineering,it is crucial to judge the stability of slope by using dynamic displacement monitoring data.On the basis of analysis displacement evolution characteristic of typical landslide,combined with the practical practice in slope of Shengli Eastern No.2 Surface Coal Mine,by organizing and analyzing the monitored displacement results of the monitoring points set at southern slope,the dynamic stability of surface mine down-dip soft rock slope is analyzed,the slope's relatively unstable area and the potential landslide mode predicated.The results prove as follows:the southern area of the slope is in stable condition on the whole,the east area is relatively unstable,and the main reasons for the severe deformation are the existence of F68 fault and the exposure of weak layers of coal baseboard seam,the potential landslide mode is shear-translational sliding with F68 fault as side boundary and weak layers of coal baseboard seam as bottom boundary.This could guide the proposing of rational measures about landslide control,and has some reference significance for similar slope engineering.
