Deformation of underground excavations under conditions of the Gremyachinsk potassium salt deposit

Autor: A. A. Udartsev, I. A. Morozov, N. L. Beltyukov, V. N. Toksarov

Publikováno v: Mining informational and analytical bulletin. :113-124

The analysis of rock mass deformation around permanent excavations in sylvinite seam at a depth of 1100 m is presented. Surrounding rock mass features occurrence of hard anhydrite-dolomite rocks in the roof and soft carnallite in the floor of undergr

Monitoring the Stress-Strain State of Marginal Saliferous Rock Mass

Autor: Artem Udartsev, V. N. Toksarov, A. A. Baryakh, V. A. Asanov, I. L. Pan’kov

Publikováno v: Procedia Engineering. 191:925-934

To reduce the risk of accidents in underground deposits of water-soluble ores, a flexible system of geomechanical monitoring of mine safety is required. Many years of experience in studying the physical and mechanical properties and stress-strain sta
