Bending Moment Characteristics of Hard Roof before First Breaking of Roof Beam Considering Coal Seam Hardening
The mechanical properties of a coal seam affect the distribution of support pressure. Considering the strain hardening effect of coal seam, the support pressure relationship of three zones—softened, hardened, and elastic—of a coal seam with regard to a hard roof is proposed, and methods to determine...
