Instability Mechanism of Voussoir Beam and Roof-Cutting Pressure Relief in Parallel Goaf: A Case Study of Shiyangou Coal Mine

During coal mining, parallel voids ahead of an advancing working face often trigger intense dynamic loading and structural instability, posing significant risks to operational safety. Using the 43,201 working face of the Shiyangou Coal Mine as a case study, this research investigates the mechanisms...
