Spanish miners are on strike amid fears their entire industry is about to go to the wall.
About 40 coal mines remain open in Spain, employing some 8000 people, mostly in the industrialised north.
The two biggest Spanish unions, the CCOO and UGT, began the four-day strike on Wednesday. They plan to stage a big rally in Madrid at the end of the month.
The government has slashed the coal industry subsidy by two-thirds, and for an industry that has lost 40,000 workers in the last two decades, it is being seen as the final straw.
Without the subsidy Spanish coal will be more expensive and unable to compete with foreign imports and other forms of energy.
Eight miners have been barricaded underground in Leon since Monday in protest at the subsidy cut.
