The Method of Construction of the Spraying of the Concrete Lining in the Vertical Openings

Abstract

The method of building the spill-concrete walls in mine holes of large diameter is analyzed. The variant of calculation of thickness of spill-concrete walls using such a method is offered. The recommendation on perfection of technology of timbering the mine holes of large diameter with a purpose of providing the durability and cost efficiency during the building of walls in vertical mines is proposed.
