ABSTRACT A method of extracting hydrocarbons, energy andother products in situ from an underground coal deposit. Aselected part of the coal deposit is heated by electricalinduction to temperatures high enough to effect the destructivedistillation of coal. The gases and liquids so produced arecollected. Next, air or oxygen is injected into the remainingdeposit which consists primarily of coke in order to burnit in place. The hot combustion gases thereby yielded are ledto the surface of the deposit to generate energy. Lastly, theheat remaining underground after the coke has been burned isextracted by injecting water o? steam into the deposit. Theresulting steam is conducted to the surface to drive a steamturbine. The electrical induction heating is convenientlyeffected by passing a selected time varying current through aconductive path encompassing that part of the coal deposit tobe heated.
