Hundreds of cliff collapses and large surface cracks have been recorded by Mr Chris Jonkers at the Baal Bone Colliery, but nothing has been done to reduce the cliff damage in the 28 years of mine operation. To obtain the GoogleEarth.kmz file by Chris for visual picture of the damage above the colliery's longwall panels can be forwarded by email: contact firstname.lastname@example.org The six most recent cliff falls are sites numbers 107, 111 to 114 and 227 and occurred in 2009 above Long Wall 28 at the Colliery. (You need to have the GoogleEarth (a free program) for these above data to work on your computer).
The GPS co-ordinates and a brief description for over 200 damage sites are available here.(see attached .pdf 71KB) This free data from the Mr Chris Jonkers of the Lithgow Environmemnt Group regarding coal mining abuse done to NSW's equivalent of the Bungle Bungle Range in Western Australia.
