Abstract

This method and device are implemented in the energy industry and the underground gasification of fuel. The implementation thereof provides effective gasification process. The method for directing gases consists of using only one drilling for supplying an oxidizing gas and discharging the resulting gas and during the gasification the flow of the oxidising gas increases with the distance from the reaction zone which leads to increase in the linear speed of the oxidising gas and it reaches the reaction front which moved away. The device for implementing the method consists of a casing pipe (1) with pipeline (3) for an oxidizing gas that is mounted coaxially in the pipe and the casing pipe (1) is open in its bottom end with perforations in the walls. The lower part of the pipeline (3) contains a chamber (5) with at least one row of perforated openings (6).
