Physical Characteristics of Section Coal and Rock Pillars Under Roof Shock Disturbances From Goaf
The stability of a rock strata structure is closely related to its response physical characteristics under external shock disturbance. The roof shock disturbance from goaf is usually one of the important factors that cause coal and rock pillar instability. It is necessary to study the dynamic physic...
