Description
Известен способ подземной газификации горючих с подачей воздушного или обогащенного кислородом дуть через сопло, иаправленное вдоль газифицируемой выработки. Этим приемом пользуютс также и при сбойке скважин по пласту.The known method of underground gasification of combustible with the supply of air or oxygen-enriched to blow through the nozzle, and directed along the gasified production. This technique is also used when joining wells along the formation.
Однако интенсивное выгорание угл у забо дутьевой скважины часто приводит к обрушению к ровли в районе скважины, что затрудн ет или даже совсем прекращает доступ дуть к огневому забою.However, intense coal burnout at the blowhole well often leads to collapse of the well in the area of the well, which makes it difficult or even completely stops access to blow fire.
Согласно насто щему изобретению, нредлагаетс в газифицируемую выработку до точки выхода дуть подавать вод ной пар или инертный газ, например, продукты каталитического сжигани газа.In accordance with the present invention, water vapor or inert gas, for example, products of catalytic gas combustion, is blown into the gasified production to the exit point.
При этом дутьева стру оказываетс окруженной слоем ине ртного газа, который на значительном рассто нии предохран ет угольную поверхность от соприкосновени с кислородом и преждевременното выгорани .In this case, the blast jet is surrounded by a layer of inert gas, which at a considerable distance prevents the coal surface from contact with oxygen and premature burnout.
Инертный газ может подаватьс между обсадной и дутьевой трубой поThe inert gas can be supplied between the casing and the blast tube.
трубке внутри дутьевой трубы или через соседнюю скважину.tube inside the blast tube or through an adjacent well.
Продукты каталитического сжигани газа отличаютс почти полным отсутствием в них кислоро-да (в них содержатс только СО, No и пары воды), благодар чему они весь.ма удобны дл применени в качестве инертного газа дл подачи в забой.Products of catalytic gas combustion are characterized by an almost complete absence of oxygen in them (they contain only CO, No, and water vapor), due to which they are all suitable for use as an inert gas for feeding into the bottom.
