The History Channel program Life After People focuses on how civilization would fare if humans instantly vanished. One episode says that one hour after people, unattended oil refineries blow up in flames. Another episode says that simple gas leaks are enough to turn residential neighborhoods like Levittown, New York, into raging infernos.
Yet the show does not cover the fate of humanity's primary fossil fuel--coal. When humans instantly disappear (how they did is not relevant to the show or the question), what fate will befall the coal factories?
