摘要
Abstract
Large-scale deformation (or large landslide) are easily formed in the bedding slope of opencast coal mine.This kind of deformation is difficult to prevent and control,and is also the major hazard of mine safety and efficient production.By systematically studying the recent real instability cases of bedding slope of stratified rock mass in opencast coal mine,the types of landslide and instability module under different conditions in opencast coal mine are analyzed,the combination method including numerical simulation and deformation monitoring and data inverse analysis is used to analyze the deformtion and instability mechanism.Measures and suggustions for this kind of slope stability control mining technique are proposed.Practice has proved that control mining technology works well.关键词
