Fracture-seepage characteristic zones of the overburden of extra-thick coal seams: Evolutionary patterns and their engineering applications

Fracture-seepage characteristic zones of the overburden of extra-thick coal seams: Evolutionary patterns and their engineering applications

Objective and Methods Given that the overburden’s structure significantly influences pressure relief gas extraction, this study aims to explore the gas migration patterns of the overburden of thick coal seams during coal seam mining. To this end, this study analyzed the evolutionary patterns of the...
