I knew a couple of these... couple I didn't... (pistachios, really?!?!?!). I had never looked into it before, but I had always assumed the coal problem was due to the sulfur content and the reaction with water and air causing it to heat... but yeah, this is why coal mines like to catch fire so easily. It doesn't take much to ignite coal particles in the air when the rock itself is already reacting and heating to water and oxygen in the air.

Tedium... It's good in some places in games, but it has to be balanced with some reward for implementing such a mechanic (and "prevention of the loss of material" isn't reward enough.) Add in we have enough other tedium that needs to be removed, and I say a big "no."
