ATTACHMENT METHOD OF MINING FACE DURING DEVELOPMENT OF STEEP BEDS WITH GOAF STOWING

摘要

FIELD: mining. ^ SUBSTANCE: method involves installation of individual posts and attachment of an air track with the reinforced support. Development of the bed is performed with sub-levels along the strike after the mining face. Individual posts in the mining face are installed between the sections consisting of protective elements. During movement the protective elements are supported on supports and bearings installed on individual posts. As disassembly chamber for the face support there used is a flank coal chute. ^ EFFECT: increasing working conditions of miners, increasing labour productivity, reducing labour intensity of mining work and production cost of coal. ^ 7 dwg
