Oct 2012 Presentation - Converting CVC to Miniwall
Oct 2016 Presentation - Chain Valley Miniwall Performance
Peter Ross - LDO Group & Lake Coal
Slide 4 - Chain Valley Colliery Mine Workings Map adjacent Wallarah & Moonee Colliery
Slide 11&12 - 86.2m Miniwall face equipment detail
Slide 14 Miniwall Production tonnages & retreat distances
Slide 15 Shears per shift
Slide 16 Total coal production - 2016 = 122 staff 10,000 tonnes/man year.
*********
Its moved on a bit since 1997-1998.
Looks like the CVC Miniwall Operation in Fassifern Seam with 200-230m cover works better at CVC than it did at Moonee in the Great Northern Seam ie no reported goaf hanging up and subsequent wind blast
CVC 2012/04 Extension Project
Wind Blast PPE at Moonee Pg8 shows being Kitted up for the "Red Zone" with Dirt Bike riding Armour and Full Face Helmet
Wind blasts in longwall panels in underground coalmines
