(Adds Blackwater production)
MELBOURNE, March 12 (Reuters) - BHP Billiton said it has suspended its Blackwater coal operations in Australia after a worker at the mine, a father of two and grandfather of two, was killed in a truck accident on Thursday.
The accident at the mine, one of seven owned by the BHP Billiton Mitsubishi Alliance (BMA) in central Queensland, involved a raptor transporter vehicle, BHP said.
Blackwater is the second-largest among BHP's metallurgical coal mines. It produced 3.5 million tonnes in the six months to December, making up one-fifth of BMA's output.
The accident at Blackwater is the second at a Queensland coal mine in the past month. One worker was killed and another was injured at Anglo American's Dawson coal mine in February when a truck tire exploded during a tire change.
