GROUNGING THE EFFICIENT TECHNOLOGY OF CONSTRUCTION MINE SHAFTS CONJUGATIONS IN COMPLICATED MINING AND GEOLOGICAL CONDITIONS

Abstract

Complex geo-mechanical and geo-physical studies
of both the stressed-deformed segmental lining
state and surrounding rock mass per-formed during the"Ventilation" shaft sinking up to a depth of
1200 m, showed that currently used technological
schemes and parameters of shaft lining and workings’ insets not fully meet the conditions of lowstrength high-intensified rock mass; owing to this
the stresses level in shaft lining increases that leads
to their fault. In view of this, the improved technological scheme of sinking vertical shafts conjugations with horizontal workings is proposed with
due regard for the features of construction in tectonically stressed rock mass at great depths.
