Tulub S. Geomechanical Foundations and spatial-technological solutions of providing mine workings stability of complicated-structure fissured rock Massifs

The dissertation is devoted to the elaboration of geomechanical foundations and the ways of increasing the stability of mine workings on the basis of usage the regularities of deformation of complicated-structure fissured rock massifs which contains artificial cavities.The constructions of frame-anchor support are substantiated, elaborated and implemented for the preparatory mine workings which are under the influence of purification works. In order to increase the chambers stability the possibility of their protection on account of compensatory mine workings has been substantiated and new constructions of basements of escalating machines for the conditions of rock swelling have been recommended. It is proved that the mine workings stability depends on the angle of crack falling and azimuth of mine working conduction, and on this basis geomechanical regularities of complex of mine workings in complicated-structure fissured rock massifs have been substantiated and stated.
