The regularities of rock mass stressed state formation in the upper part of the Earth crust
Abstract
It was determined that in the upper part of Earth crust up to 500-600 m depth the rock mass stressed state in some areas may correspond to the A. Geim, A.D. Dinnik, N. Hast hypotheses, as well the hypotheses developed in UB RAS and is mean interchanged for 11 year cycle of solar terrestrial relations. During this cycle 2-3 years rock mass consolidation is observed, and progress on displacement is absent or very small; then rock mass compession decreases for 3-4 years and is accompanied by an array of fault events, after that rock mass consolidation is again observed for 1-2 years. Further, both rock mass and earth’s crust compression increases for 4-5 years accompanied by thrust phenomena. The analysis of stresses values in the elements of mining systems shows that by 2020-2030 years the access to minerals in these workings at over 500 m depth will be difficult.
