the idea is good, but there is big chance of sinkhole.

is there no any other option, some like injecting some chemicals that may cause some sort of reaction that would vaporize the coal like naphthalene...i mean some other way instead of burning some crazy fire on the buttocks side???

The coal should ne extracted somehow instead. This is wasteful.

They have built a test condenser on coal power plant and its "pumped" cooled off smoke makes all the liquid fuels based upon the tap location of the condensing coil this one is just an atmospherically cooled straight pipe

Use the fracking system similar to shale gas production and no need for underground fires its logically stupid. In the Soviet union they used nuclear weapons to cut out gas in Ukraine and Uzbekistan in the 1970s, two were used in Ukraine one for a gas field and the other a coal mine.
