| 摘要 |
A system for gasification of coal deposits below the ground surface comprising an injection well assembly comprising one end positioned at the surface and the opposite end located adjacent or within the coal deposit; a production well assembly comprising one end positioned at the surface and the opposite end of the production well assembly located adjacent or within the coal deposit; a non-vertical reaction shaft assembly located adjacent or within the coal deposit, the non-vertical reaction comprising an injection end in communication with the end of the injection well assembly located adjacent or within the coal deposit and a production end in communication with the end of the production well assembly located adjacent or within the coal deposit; and an electric torch configured to move within the non-vertical reaction shaft assembly and create an oxidant and moderator downhole. A method for gasifying coal deposits is also provided.
