Abstract:
1. A method of recovering gas from a subterranean formation comprising: digging a shaft toward the subterranean formation; constructing a ventilated underground control center, wherein the center is located within the subterranean formation; providing a computerized control panel, wherein the panel is located within the underground control center; providing a drill pipe, wherein the pipe is extendable, rotatable, and hollow, wherein the pipe has a proximal end and a distal end, and wherein the pipe is operatively connected to the ventilated underground control center at the proximal end; providing a hot head device, wherein the hot head device is operatively connected to the pipe at the distal end of the pipe; providing a power source, wherein the power source is operatively connected to the computerized control panel by power source electrical means, and wherein the power source is operatively connected to the hot head device by the drill pipe; providing a movable hydraulic shield, wherein the shield is located behind the hot head device; providing a movable resin roof bolting machine, wherein the bolting machine is located behind the movable hydraulic shield; operating the computerized control panel, wherein the power source activates the hot head device, and wherein the hot head device vaporizes the subsurface formation to obtain a gas; and recovering the gas.
