Main Content

2011 was another successful year at Mandalong, maintaining its record production results together with its exemplary safety performance. The year also saw Mandalong Mine expand its community focus, the mine’s operations and infrastructure, and further develop its environmental initiatives.

With an emphasis on improving work practices, devising innovative environmental initiatives, creating a safe and happy workplace for all our employees, and further increasing the mine’s community involvement, Mandalong continues to seek new ways to promote and achieve improvements in its performance to benefit all stakeholders.

For example, Mandalong has been upgrading its facilities to ensure that the mine continues to improve its operating efficiency, improve safety in the workplace for our people and generally further enhance our operations. The mine has constructed a new bathhouse, improved car parking facilities, developed road ways and built a haul road which links our Cooranbong facilities to Newstan, Centennial’s regional export facility.

Mandalong, in partnership with Coal Innovation NSW and Corky’s Sustainable Energy, will trial a new methane gas conversion system, Ventilation Air Methane Regenerative After Burner (VAM RAB) which is hoped will assist to improve the mine’s environmental performance. For more information on this system please see the December edition of the Mandalong Mailbox  - the mine’s community newsletter under Community Consultation below.
