Physical simulation of integrated protective structures

An effective way of protecting development workings by
integrated rock wall structures is considered. The necessity of improving
this method and its experimental verification is substantiated. Integrated
rock wall structures are experimentally tested under laboratory conditions.
On the basis of the results of physical modeling, parameters of integrated
structures have been specified in terms of impact factors; their yield
strength is also specified. The condition for ensuring the stability of the
integrated protective structure, which allows calculating appropriate rock
wall width, is determined.
