Abstract
1. Способ подземной газификации угольного пласта, включающий бурение дутьевых и газоотводящих скважин с каналами по угольному пласту, крепление стенок скважин обсадными колоннами труб, розжиг угольного пласта, подачу дутья и отвод образующегося газа, отличающийся тем, что, с целью повышения теплоты сгорания газа за счет непрерывного перемещения точки подачи дутья вслед за перемещением фронта газификации, канал дутьевой скважины в пределах прохождения по угольному пласту обрабатывают неогнеупорным раствором от обсадной колонны до места, расположенного от забоя дутьевой скважины на расстоянии, равном шагу обрушения пород.2. Способ по п.1, отличающийся тем, что в качестве неогнеупорного материала используют цемент.1. A method of underground gasification of a coal seam, including drilling of blast and gas exhaust wells with channels through the coal seam, fixing the walls of the wells with casing strings, igniting the coal seam, blowing the blast and discharging the resulting gas, characterized in the expense of the continuous movement of the point of supply of the blast following the movement of the gasification front, the channel of the blast hole within the passage through the coal seam is treated with a non-refractory solution from the casing to the places Located on the blow bottom wells at a distance equal porod.2 collapse step. Method according to claim 1, characterized in that cement is used as a non-refractory material.
