Study on Deformation Characteristics of Surrounding Rock of Roadway with Coal–Rock Interface
Sustainability, 2023 Surrounding rock of roadway with a coal–rock interface is a common form in coal mines. In order to determine deformation characteristics and obtain the control principle of roadways with a coal–rock interface, the interface between the roof and coal seam was added to simulate the weak cohesion between the stratum.
