Destruction of rocks by the non-explosive depleting compounds during mining
(National Mining University, 2016-03-30)
Purpose. Justification of the possibility of non-explosive coherent rocks destruction while carrying out stratal underground mine workings on the basis of the set of dependencies describing changes in physical and mechanical ...
Local reinforcing of footing supported in the destroyed rock massif
(National Mining University, 2017-03-30)
Purpose. Justification of feasibility of non-explosive destruction of hard rock during in-seam workings based on the obtained dependences related to changes of physical and mechanical properties of non-explosive destructive ...
Analyzing kinetics of deformation of boundary rocks of mine workings
(National Mining University, 2018-12-30)
Purpose is to analyze nature of rock deformation and to estimate experimentally state of mine workings being supported under the conditions of areas disturbed by coal mining.
Methods. The studies involved field instrumental ...
Studies of new nonadhesive anchoring
(National Mining University, 2018-06-30)
Purpose is to develop anchoring with nonadhesive high-strength roof bolting in terms of large pre-destructive deformations and its testing under laboratory conditions.
Methods. Laboratory studies of hydration hardening ...
