In Joban coal field, some collieries are fl ooded by spoutings of hot spring, and considerably damaged. From previous experiences, the natures of such spoutings can be expressed by Q=
aebt2and by this empirical formula, rate of discharge can be predetermined immediately by the observation of initial spouting discovered. Rate of discharge decreases as hydrostatic head increases, which is expressed by Q=K√h. When flooded water is closed by dams, the pressure on the dams can be expressed by
p=t/a+t and also tells if a new source of water is pumped into the dams, certain quantity will flow back to the hot spring source.
