INDUCTION HEATING OF COAL IN SITU |
摘要 |
<p>The electric induction heating in situ of a selected portion of an underground coal deposit, for the purpose of facilitating extraction of gases, liquids, solids and energy from the deposit. The heating is conveniently effected by passing a time-varying electrical current through a conductor encompassing the selected portion. The conductive path is preferably a toroid, quasi-toroid, helix, or simulated toroid, quasi-toroid or helix, created by a drilling and passing one or more conductors through the drill holes.</p> |
