A method for automatically shortening an injection well liner for underground coal gasification is provided in which portions of the injection well liner melt during the underground coal gasification process to shorten the injection well liner.

Method for shortening an injection pipe for underground coal gasification

A sacrificial liner linkage that can be used to automatically shorten a liner for an underground coal gasification process is provided. The sacrificial liner linkage may be one or more sacrificial liner linkage portions that are spaced between one or more liner portions in which the sacrificial liner linkage portions disintegrate before the one or more liner portions to automatically shorten the liner.

Sacrificial liner linkages for auto-shortening an injection pipe for underground coal gasification

A method for automatically shortening an injection well liner for underground coal gasification is provided.

A process is provided for making a free flowing granular product from moisture laden caked coal fines, such as wet cake, by mixing a water immiscible substance, such as oil, with the caked coal, preferably under low shear forces for a period of time sufficient to produce a plurality of free flowing granules. Each granule is preferably comprised of a dry appearing admixture of one or more coal particle, 2-50% by weight water and the water immiscible substance.
