摘要： A method of mine-less connection of wells for underground gasification by the filtrational fire connecting technique is intended primarily for forming a single unitary gasification channel for underground gasification of coal, oil shale and oil-bearing beds. In the disclosed method of connecting wells or boreholes drilled for underground gasification, the coal bed is ignited in one of the wells situated in the direction of formation of the unitary gasification channel. After a center of combustion has been set in this well, an air blast is directed at a permanent flow rate into the well with which the connection is to be effected. The pressure of the air blast charged into the well is measured, and when the pressure drops considerably, an air blast is charged for connection purposes into the next successive well in the direction of formation of the gasification channel. The disclosed method provides for maintaining the combustion source in the area of the well connected with the gasification channel and thus for ensuring reliable formation of the unitary single gasification channel.
摘要翻译：通过过滤火连接技术对地下气化井进行无缝连接的方法主要是形成煤，油页岩和含油床地下气化单一的单一气化通道。在所公开的连接钻井或钻孔用于地下气化的井眼的方法中，煤层在位于整体气化通道形成方向的一个井中点燃。在该井中设置了燃烧中心之后，将空气鼓风以恒定流量的速率引导到与其进行连接的井中。测量装入井中的鼓风的压力，当压力显着下降时，在气化通道的形成方向上将连续气体充入下一个连续井中。所公开的方法提供了将燃烧源保持在与气化通道连接的井的区域中，并且因此用于确保整体单一气化通道的可靠形成。
