Study on Size Design of Shaft Protection Rock/Coal Pillars in Thick Soil and Thin Rock Strata
To prevent serious shaft deflection disasters under asymmetric mining conditions, it is urgent to solve the problem of designing shaft protection rock pillar (SPRP) sizes in thick soil and thin rock strata. In this paper, based on the parallel mining model and the perpendicular mining model, a dynam...
