The owner of Maltby Colliery has warned that the mine could be closed - leaving around 500 jobs at risk. Hargreaves Services says the mine may be mothballed as it 'would probably be uneconomic to switch production' to another process.
Maltby produces more than a million tonnes of coal per year, about 60% of which goes to Drax, Europe's largest coal-fired power plant. Much of the remaining product goes to Hargreaves' Mockton works near Barnsley.
