Features of Origination of Load on "Support-Interframe Shield” System

https://doi.org/10.17073/2500-0632-2019-3-202-212

Abstract

The features of originating load on “support-interframe shield” system in the process of formation of broken rock zone around a mine working were investigated by laboratory tests on models of equivalent materials and structural models. The role of interframe shield in the formation of frame support load has been revealed. It was found that a natural self-supporting arch is formed over interframe shields within the broken rock zone, which redistributes the load on the roof support frames, while the weight of rocks within the arch puts pressure on the interframe shields. The requirements for interframe shield of frame supports in mine workings have been developed.
