Study on the law of surface subsidence in layered mining of thick coal seam with medium hard roof
Abstract In this study, the change law of the surface subsidence coefficient under the condition of thick coal seam layered mining was investigated. The study is based on the measured subsidence data of the 1210-working face of the Mengba mine surface mobile observation station after the first- and...
