Research of physical and mechanical properties of argilliferous bearing strata

Authors: M.I. Stupnik, Candidate of Technical Science, Associate Professor, Kryvyi Rih Technical University, Kryvyi Rih, Ukraine

Annotation:

Due to the carried research it has been determined that the increase of moisture in clay rock provokes a swelling phenomenon and ore plasticity maximizing; the decrease of moisture causes the rock subsidence phenomenon, which affects negatively the underground mining technology.
