A coal vein also has more blocks in a vein, and since adjacent ores have a chance to explore, larger veins have a bigger chance of an explosion. I think that explains what you have experienced.

However, it can also be what you say about mining coal - since there is so much coal, the odds that a given explosion is happening in a coal area is indeed larger.
