Abstract:An urgent problem in mining practice is to determine the loads on guard-type supports in flat-lylng and inclined (semlsteep) seams.In this article we will discuss one approach to the construction of load calculation schemes based on investigations of the deformation mechanisms of loose materials beyond the support and of the surrounding rocks [i, 2].i. Experiments performed by the method in [3] for seems dipping at ~ < 60 = have revealed that for certain displacements of the support, the material (dry sand) be… Show more
