UTILISATION METHOD OF WORN-OUT AUTOMOBILE TYRES AT DEVELOPMENT OF COAL BEDS BY UNDERGROUND GASIFICATION METHOD Russian patent published in 2011 - IPC E21B43/295 B09B3/00 

FIELD: mining.

SUBSTANCE: method involves preparation of gas generator for gasification by drilling a network of wells: vertical ones for blast air supply, formation ones for gas removal; in addition, between blast air and gas-removing wells there drilled are formation wells through which wastes are supplied to combustion source, combustion face is moved along the rise and spread of coal bed by supplying the blast air to blast air wells and gas removal through gas-removing wells. At that, as utilisation wastes there used is rubber of pre-crushed automobile tyres, which is supplied to combustion source when necessary through the dosing devices installed in formation wells.

EFFECT: increasing operating efficiency of underground gas generator at coal gasification, owing to using flammable material of worn-out automobile tyres at their gasification.
