Answer 1

Control is the difference. You gasify coal or oil shale underground by burning a little of it to gasify a larger amount. To control this you vary the amount of air pumped down. Out of control underground coal fires, like in China and Indonesia, occur when you've got no way of shutting off the air supply.

Answer 2

involved events would desire to come at the same time and extinguish it or pay for it to be extinguished. perchance the county is going in on the fee. do in basic terms not assume somebody from Arizona to pay for a coal hearth in Pennsylvania.
