Whole of Mine Management
DeltaSBD will take over operations at Berrima Colliery from Berrima Coal Pty Ltd from 1 September 2009. Berrima Colliery is an underground coal mine located at the end of Medway Road, Medway. The colliery holding is owned by Blue Circle Southern Cement Ltd’s parent, Boral Ltd.
DeltaSBD was responsible for the total operation of the new Wongawilli NRE Colliery, which was purchased from BHP Billiton by Gujarat NRE in 2008.
DeltaSBD took over the operation of the former Elouera Colliery on behalf of BHP Billiton in 2004. Operations included both development and longwall operations, as well as all environmental requirements and mining approvals. This operation required the provision of more than 110 personnel (including all statutory personnel). Delta operated the mine from October 2004 to April 2006, with care and maintenance continuing until the mine was purchased by Gujarat NRE in December 2007.
DeltaSBD also operated Central Colliery on behalf of AngloCoal. DeltaSBD took over the complete operation in 2006, including longwall operations. This required the provision of more than 70 personnel (including all statutory personnel).
