The amount of its coal sold fared even worse with a Yancoal’s Chinese parent revealing it was down 13% year-on-year to 4.4Mt in a Hong Kong Stock Exchange filing.

However, the figures for the first half of 2014 were stronger with total saleable coal production up 11% year-on-year to 9.6Mt and sales volumes up 4% year-on-year to 7.9Mt.

Yancoal restarted production from a new panel in the Austar mine in the Hunter Valley on June 23, more than two months after a wall collapse killed two members of a development crew underground on April 15.

Yancoal has seven operating mines in the country including the Moolarben mine which has expansion plans to eventually reach 17Mt per annum.
