Abstract: In order to reduce maximally disasters and accidents caused by suface coal mine landslides, and realize maximally production efficiency at segment existing hidden danger of slope stability, a lot of larger surface coal mines have used slope radar technique for forecasting landslides. On the basis of the practice, this paper introduces the application of radar technique in predicting the landslide location, time and sliding soil mass. The result shows that the technology is a new, practical and effective method in landslide forecast aspect.
