We can use the Fischer-Tropsch process to convert the coal to more usable forms. We aren't going to just let all those delicious hydrocarbons go to waste.
The Fischer-Tropsch process can turn coal into liquid hydrocarbons, but it is not energy efficient. Its feedstocks are hydrogen (currently mostly produced at a loss from methane, i.e. natural gas) and carbon monoxide (produced from the coal). If you have the Hydrogen, you can just use it directly, e.g. in a fuel cell, and burn the coal for electricity or heat. The Fischer-Tropsch process is only interesting if you need liquid fuels, say for operating tanks or aircraft, and don't have more efficient sources.
You can make hydrogen from coal coke and water using the "water gas" and Lowe process. These were used to produce "town gas" that was used for domestic heating and lighting from the 19th century until it was replaced by methane natural gas: https://en.m.wikipedia.org/wik...
...My only complaint is that the self illumination no longer functions as the tritium in the hands and hour markers has gone through over 3 half lives.
Mine still glows faintly in a dark room. The radium in the paint has a half life of 1600 years, but the zinc sulfide fluorescent media has degraded.
