Research on mechanism and application of compound roof cutting and pressure relief control in thick sandstone roof mining roadways

Thick sandstone roof strata exacerbate surrounding rock deformation and failure in roadways, posing a severe threat to safe and efficient coal mine production. To address the challenge of controlling surrounding rock in high-stress roadways under such conditions, a novel composite roof cutting and p...
