Actually, I even thought it was a fact that some kind of earthquake, earth movement was the cause.
Since the collapse happened the media has had on all sorts of folks (lots of union people with a grudge) saying it wasn’t an earthquake. And, some scientists at a Utah university are saying it wasn’t.
There’s also a mindset with many that coal mining is evil, so you have some that want to believe the worst.
I don’t know, I don’t think anyone does at this time, what caused the collapse, despite the theories being thrown around. I feel the mine owner was going to be portrayed as evil no matter what. I feel really bad for him, he is distraught. But from I understand the mine operation was approved by the fed agency responsible for overseeing operations.
