Abstract:The secret to guaranteeing roadway stability is the logical choice of parameters that sustain the roadway.Using the transportation roadway of a particular mine as the engineering model, examine the deformation and failure status of the roadway based on the analysis of the rock mass structure in response to the issue of severe deformation in high altitude breaking rock mass. The loose circular of the roadway was subjected to acoustic testing; its thickness ranged from 1.2 to 1.4 meters. The roadway support''s loose circle was categorized as a Class II medium loose circle. The aforementioned research served as the basis for the first estimation of the support parameters, which were then optimized using numerical simulation tools. When spray concrete is used with a thickness of 100 mm and an anchor mesh degree of 1.2m×1.2m along with an anchor rod length of 1.5m, the combined support can satisfy safety regulations. The study''s findings offer a theoretical foundation for the roadway''s support design in the mining region as well as design and construction guidelines for related projects.
