Dynamic response characteristics and failure mechanism of coal-rock combination under different immersion conditions
Artículo
Artículo
BackgroundIn practical engineering, the waterproof coal pillar usually suffers from different degrees of dynamic load from the overlying strata, and its internal water distribution is non-uniform. Although the traditiona...
