The study of mechanical properties and fracture evolution of coal-rock masses under hard roof-soft floor conditions
Abstract As the depth of coal mining in China continues to increase, the fracturing of coal rock masses has an increasingly complex impact on the surrounding rock roadways. The majority of the mine’s roadways run through coal rock masses with hard roofs and soft bottoms, which typically exhibit comp...
