May 14 (Bloomberg) -- Leighton Holdings Ltd., Australia's largest construction company, won a $350 million contract for a coal mine expansion in Indonesia, the largest exporter of the fuel used by power stations.

The expansion of PT Mahakam Sumber Jaya's MSJ coal mine will be completed in April 2013, the Sydney-based company said today in a statement. Leighton also said its 45 percent owned Middle Eastern venture, Al Habtoor Leighton Group, won a AED$1.2 billion ($327 million) contract from Mubadala Development Co. to design and build a university campus in Abu Dhabi.

Chief Executive Officer Wal King is pursuing growth in Asia and the Middle East to replenish his order book amid concerns a global slowdown would curb available contracts. Indonesia is building new mines as prices for the fuel almost doubled in the past year.

``We have now won over $1 billion in new mining work in Indonesia over the past 12 months, and we have identified a number of additional opportunities,'' Leighton International Managing Director David Savage said in the statement.

Leighton fell 7 cents, or 0.1 percent, to A$49.88 at 10:53 a.m. in Sydney trading. The shares have tumbled 23 percent since reaching a record high of A$64.50 on Dec. 6.

Leighton has been operating the MSJ coal mine since 2004, it said. Construction of the Paris Sorbonne University campus will be complete in August 2010, Leighton said in a separate statement.

Spot prices for power station coal from Australia's Newcastle port, the largest coal-export outlet in the world's second-biggest exporter, more than doubled in the year to May 2, according to McCloskey Group Ltd.

Leighton, a subsidiary of Germany's Hochtief AG, in April won a A$1 billion order to develop and operate a mine at the Chitarpur coal project in India's Jharkhand state for 20 years. In March it won a A$720 million order to build pipelines for Oil & Natural Gas Corp., India's biggest fuel producer.
