Research on failure criteria and collapse height of roadway roof strata based on energy accumulation and dissipation characteristics
Abstract Roof collapse is a form of rock failure driven by energy release. The rectangular elastic thin plate (RETP) model, widely used in coal mining engineering research, reflects the law of the movement of overlying strata of a coal seam. The stress distribution regularity of each delamination ca...
