Research on Roof Structure Model and Reasonable Support of GSER by Cutting Roof in Three-Soft Coal Seam
https://doi.org/10.58531/ijge10310003
Abstract:
In order to reveal the deformation mechanism of surrounding rock in the three-soft coal seam with GSER(GSER), through physical simulation experiment, the roof strata fracture evolution under the three conditions of no roof cutting general support, top cutting high-strength support, and roof cutting public support is simulated, the roof structures mechanical structure m...
