Determination of bearing capacity of fractured direct roof in the bottom-hole space of mine workings
Abstract
On the basis of studying the mechanism of formation of pressure cracks and roof movement within the unfixed part of the bottom-hole space and face faces of low-lying formations of Donbass it is established that the immediate roof should be considered as a system having a block structure ...
