PROCESS OF OUTGASSING OF COAL SEAM Russian patent published in 1996 - IPC

Abstract RU 2062883 C1

FIELD: mining industry. SUBSTANCE: invention can be used to control gas while working coal seams. Boreholes are drilled in mass of coal and are made gas-tight. Amount of gas escaping in natural way is brought to stoichiometric concentration. Formed explosive mixture is initiated by means of filament spiral. After explosion of mixture gas starts escape actively through formed system of cracks. EFFECT: increased operational efficiency of process. 5 cl, 1 dwg
