Yancoal Australia Limited (ASX:YAL) is aiming to raise about $US2.3 billion in a subordinated capital notes offer.
The coal miner says the pro-rata, renounceable rights offer will comprise 2.32112 notes for every 100 Yancoal shares.
The raising comes amid sliding commodity prices and the company says it will be used to strengthen its balance sheet and may fund future expansion.
It will also apply $US1.8 billion to repay existing loans and improve its gearing ratio.
CEO Reinhold Schmidt says it aims to reduce its gearing, improve operational efficiencies and deliver significant cost savings to weather the challenges of an increasingly competitive marketplace.
Yancoal reported a net loss of $192.7 million in the 2014 financial year.
