Zakharova L. Dissipative structures evolution during irreversible deformation of the rock mass

Thes is for a Doctor's degree of Technical Sciences in specialty 05.15.09 "Geotechnical and mining mechanics" Institute for Physics of Mining Processes, National Academy of Sciences of Ukraine, Dnipro, 2018. I investigated dissipative structures evolution and their parameters in space and in time due to close (immediate) interaction of rock fragments and far (aggregate) cooperation of their clusters after transition of the rock mass over strength limit. It is important for providing of the rock mass and underground roadways stability in complex geological environment. I developed a special methodology to identify the dissipative structures in the ground and rock mass and investigated parameters of these structures that characterized their evolution in time and space. Then I identified basic factors, which promote emerging of the dissipative structures in support systems that are employed to maintain the roadways stability and investigated mechanism of the structures' spontaneous generation.
