The mechanics of plastic volumetric deformation of rock and the rockburst mechanism
Izvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal, 2022 Relevance and problematics. The problem of rock pressure dynamic manifestations, primarily rockbursts and tectonic shocks, is particularly acute for both coal fields and ore deposits. Dynamic manifestations of rock pressure lead to injury and death, to kilometers of destroyed mine workings, loss of minerals, business interruption and additional costs ...
