WAY ahead of STAGED lining of mine workings

摘要

The process of advancing the phase-lining of mine workings, including the construction of advanced lining, production under her generation and the subsequent installation of a permanent lining, characterized in that before the next cycle of production from the roof in the direction of its future at an angle of -15 ° to 60 ° to the plane of the roof produce drilling in an amount not less than one per meter of roof width generating install reinforcing elements in them, then drilled wells produce injection bonding composition after curing bonding compositions conducted generation protected advanced lining, erection permanent lining produced with a delay from the bottom .
