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
mine workings along the strike of the ore body enables the use
of mobile equipment, which allows increasing performance
indicators of stopping: performance ofsecond working, labor
of face worker, labor intensity.
