PROCESS OF DEVELOPMENT OF COAL SEAMS AND COMPLEX OF EQUIPMENT FOR ITS IMPLEMENTATION Russian patent published in 1994 - IPC

FIELD: mining industry. SUBSTANCE: development of coal seams is conducted in columns or stopes by burning and gasification of coal in seam. Products of gasification after proper cleaning and preparation by electrochemical method are transformed into electric power with the aid of battery of fuel cells. Product of oxidation of hydrogen - one of basic components of fuel mixture (products of coal gasification), namely water is transformed in recovery boiler into water steam thanks to after-burning of residues of fuel used in battery of fuel cells which is fed together with inert carbon dioxide produced by oxidation of carbon oxide of fuel mixture into zone of burning of coal in seam and hydrogen and carbon oxide regenerated in it are supplied again into battery of fuel cells. EFFECT: improved efficiency of gasification of coal. 6 cl, 2 dwg
