Description

Насто щий способ закреплени  газоотвод щих выработок при подземной газификации углей отличаетс  от известных тем, что в предварительно пробуренную выработку (скважину ) опускают снабженную фон-ар ми колонну тонкостенных металлических или дерев нных труб, после чего затрубное пространство заполн етс  жидкой огнеупорной массой, постепенно обжигаемой проход щими по трубе гор чими газами.The present method of fixing the gas exhausting openings during underground gasification of coal differs from the known ones in that the previously supplied hole (well) is lowered into a column of thin-walled metal or wood pipes supplied with background, and then the annulus is filled with a liquid refractory mass gradually fired hot gases passing through the pipe.

Осуществление указанного способа производитс  следующим образом. После проходки наклонных, вертикальных и других горных выработок, предназначенных дл  вывода на поверхность газа подземной газификации , и закреплени  от обвала скважины , шурфа или гезенка (глинистыми растворами с применением хлористого кальци  и пр.), в пройденную выработку , заполненную раствором, опускаетс  колонна тонкостенных металлических труб, снабженных направл ющими фонар ми дл  центрировани . Диаметр опускаемых труб несколько меньще диаметра пройденной выработки.The implementation of this method is as follows. After penetrating inclined, vertical and other mines intended to bring underground gasification gas to the surface and fixing a well, a hole or gezen from a collapse of a well (clay solutions using calcium chloride, etc.), a thin-walled column is lowered into the completed production metal tubes provided with guide lights for centering. The diameter of the drop tubes is somewhat smaller than the diameter of the excavated output.

После спуска колонны и центрировани  ее, в затрубное пространствоAfter descending the column and centering it in the annulus

нагнетаетс  насосом под давлением жидка  огнеупорна  масса, состо ща  из мелкозернистого глиноземистого цемента с наполнителем-шамотом; после заполнени  затрубного пространства в образовавшейс  сплошной огнеупорной трубе прорезаютс  температурные швы опускаемым в трубу гидравлическим труборезом-расширителем . Температурные швы заполн ютс  способом торкретировани  эластичной огнеупорной массой, после чего производитс  розжиг огневого забо , и образующимис  при этом газами с постепенно повышающейс  температурой монолитна  огнеупорна  труба подсушиваетс  и обжигаетс . В случае применени  дерев нных труб, последние при этом сгорают, после чего труба вступает в аксплоатацию.pumped under pressure by a pumping liquid refractory mass, consisting of fine-grained alumina cement with filler-chamotte; After the annulus is filled, the temperature welds are lowered into the pipe by a hydraulic pipe cutter-expander in the formed continuous refractory pipe. The temperature joints are filled with the method of gunning with an elastic refractory mass, after which the fire flame is ignited, and the monolithic refractory pipe is dried and fired by the gases generated with a gradually increasing temperature. In the case of using wood pipes, the latter are burned at the same time, after which the pipe enters into exploitation.
