Peculiarities of roof management depending on fracture orientation and direction of excavation
Authors:
Abstract
Among the many factors affecting the behavior of the roof during excavation of coal seams, the macrostructure of rocks is of great importance. Laws of influence of side rock macrostructure on the manifestation of rock pressure in the mine workings are still little investigated ....
