Abstract Coal mine waste rock is generated dur-ing coal extraction and is usually disposed of in non-engineered dumps. The dumps are extended vertically to 100–120 m height to reduce the spatial footprint. The waste mass generally consists of loose, cohe-sionless material associated with high heterogeneity, so the dumps are prone to slope ...
