At the moment, the media is saying that the cause of the explosion is unknown (CNN reports it as such, anyway). I suspect we will find out in due time.

Recently I've got curious about such eruptions. Whatever the direct cause might be, natural gases like methane ought not to erupt in the coal mine shaft. I wonder whether the incident might have something to do with activities inside the Earth.

If there is enough methane in the shaft, a simple spark is enough to set it off. Generating sparks in a mine shaft doesn't require much effort. If I had to guess, I would say it was likely a gas pocket that was ignited.
