Rock mass preconditioning methods in underground mines and ways of its evaluation – state-of-the-art

HIGHLIGHTS

• What: The aim of this process is to decrease strength parameters of the rock mass. The aim of this method is to determine the propagation velocities of seismic waves between sources and receivers. Still, this approach has to be further developed.
• Who: CEER and collaborators from the KGHM Cuprum LtdResearch and Development Centre, Wrocław, Poland have published the research: CIVIL AND ENVIRONMENTAL ENGINEERING REPORTS, in the Journal: (JOURNAL)
• How: This paper is focused on the description of the current State-of-The-Art in rock mass preconditioning methods which are applied to . . .
