Abstract
Циклический способ подземной газификации угля, включающий бурение дутьевой и газоотводящей скважин к угольному пласту, соединение скважин по пласту гидроразрывом с созданием зоны синтеза, бутирование трещин гидроразрыва крупнозернистым песком, далее на выбоине дутьевой скважины осуществляют первый цикл розжига пласта, поочередную подачу воздуха и воды в пласт через дутьевую скважину для подогрева пласта до температуры 1600 К, и последующий поочередный отвод образованных продуктов горения и энергетического газа через газоотводящую скважину, в которой предварительно поддерживают заданные термобарические условия, отличающийся тем, что цикл оканчивается достижением в зоне синтеза расчетного уровня температуры, а с началом цикла, после прекращения подачи воздуха в дутьевую скважину, в угольный пласт на расстояние выгазованного пространства посредством вдавливания вводят перфорированную на конце трубу и через нее подают воду и СаО. The cyclic method of underground coal gasification, including drilling of blast and gas outlet wells to a coal seam, connecting the wells along the seam with a hydraulic fracture to create a synthesis zone, drilling fracking fragments with coarse sand, then the first ignition of the seam is carried out at the borehole of the blast hole, and air and water are fed into the seam in turn through the blast hole to heat the formation to a temperature of 1600 K, and the subsequent alternate removal of the generated combustion products and energy gas through the exhaust gas an atmosphere in which predetermined thermobaric conditions are previously supported, characterized in that the cycle ends with the achievement of the calculated temperature level in the synthesis zone, and with the start of the cycle, after the air supply to the blast hole is stopped, perforated at the end is introduced into the coal seam by pressing in pipe and through it serves water and CaO.
