ESTIMATION THE LENGTH OF LOVS END PORTIONS ACCORDING TO THE CRITERION OF ROCKS CONVERGENCE ACCELERATION

Abstract

Results of instrumental observations in operating
breakage face in the A.F. Zasyadko mine are cited.
It is determined that enclosing rocks convergence
rate changes in time and depends on the intensity
of industrial operations in a love. The values of enclosing rocks convergence acceleration along the
whole face line are calculated. Absolute convergence acceleration values of enclosing rocks are
less at the end sites than in the middle love part. It
is offered to use rock convergence acceleration as
geo-mechanical criterion for estimation the length
of love end sites.
