The first part of this video shows some of the old coal mine shafts at a local strip mine were they are mining the coal. There are five seams of coal that are being mined, all with old workings running through them. The sinkhole in the video show what happens when a roof collapses in the old tunnels deep under ground. The pictures at the end of the video shows what a sinkhole looks like side on when one of the old tunnels caved in underneath the high wall at the strip mine operation. These cave ins happened in the Foord seam which is 45 feet thick and have some large tunnels running through it.
