Distant interaction of rock mass clusters around underground opening
(National Mining University, 2017-06-30)
Purpose. To experimentally prove the fact of distant interaction between rock clusters during the irreversible displacements of rock mass. Disintegration of the rock mass does not necessarily imply loss in underground ...

Computational model for evaluating the state of geomechanical systems during computing experiments
(National Mining University, 2017-03-30)
Purpose. To create a model allowing integration of the diverse features identified for the rock massif behavior by differentiation of various theories and real phenomena into a single information-analytical flow.
Methods. ...
Methane Hydrates – Australian perspective
(National Mining University, 2016-12-30)
Purpose. To analyze Australian methane hydrate resources, exploration, and production, its current state and future potential.
Methods. Analysis of data published in different sources concerned with geological surveys and ...
Dependence between the height of rocks displacement zone with fissure and the size of stopes
(National Mining University, 2016-12-30)
Purpose. To establish dependences describing changes in the height of rocks displacement zone with fissure in the course of stope development using experimental data about the stopes’ dimensions and parameters of the land ...
