Instability Evolution Mechanism and Cooperative Control of Three-Soft Coal-Seam Roadway Surrounding Rock Subjected to Mining Disturbance
Using the No. 1513 return air roadway at Anyang Coal Mine as an engineering case, this study examines the instability mechanism and support control of three-soft coal-seam roadways. An integrated approach combining theoretical derivation, physical similarity modeling, and FLAC3D simulation was adopted to analyze fractu...
