    Study on the Evolution of Overlying Strata Fractures and Gas Control Technology of High Gas-Drainage Roadways Under Gob-Side Entry Retaining with Roadside Filling

    Study on the Evolution of Overlying Strata Fractures and Gas Control Technology of High Gas-Drainage Roadways Under Gob-Side Entry Retaining with Roadside Filling by Yunfei Yang, Zetian Li, Anxiu Liu, Hongwei Liu, Zhangyang Li, Hongguang Guo, Zhigang Li

    Published 2025-07-01

    In order to examine the fracture development law of overlying strata in goafs and to reasonably lay out a high gas-drainage roadway under gob-side entry retaining with roadside filling, the 91–105 working face of the Wangzhuang Coal Mine was selected as the engineering case study. The failure laws a...
