Rearguard efforts to break an impasse that has shut one of the State's biggest coal mines were unsuccessful last night, plunging the South West closer towards an energy crisis.

A week after mining operations at Griffin Coal near Collie were suspended amid a pay dispute between the contractor that runs the mine and the company that owns it, _WestBusiness _ understands the warring parties remain polarised.

Carna Civil and Mining, the Waroona-based business that manages Griffin on behalf of Lanco Infratech, ordered staff off the job last Thursday over claims it was owed up to $30 million in unpaid debt.

The row casts a pall over energy supplies as Griffin supplies coal to Bluewaters, one of WA's biggest power generators.
