Determination of room-and-pillar system parameters for transition to greater depths
Аннотация
With progress in depth, the most effective way to increase the
field of application of room and pillar system is the transition
to the combined support of the ore-concrete-ore or concreteore-concrete methods. With this arrangement, treatment of
