Abstract RU 2190765 C2

FIELD: mining industry. SUBSTANCE: method of dismantling of powered cleaning complexes includes construction of dismantling chamber with simultaneous erection of guarding support in the form of supporting members embedded in holes drilled in coal pillar from dismantling chamber towards breakage face. Supporting members come in the form of metal rods which are combined in groups of 3-5 members with joining of their ends brought out into dismantling chamber with the use of flexible tie-rod. Each group of supporting members depending on mining and technical conditions is extracted together with dismantled section of support or right after dismantling of the whole powered support. EFFECT: decreased labor input to dismantling. 4 cl, 5 dwg
