No it wasn't , it was planned & orchestrated by Thatcher & Her backers, in revenge for the Miners crippling the Heath Government. It was well prepared for, with massive stockpiles of foreign coal, stashed all over the Country. Feelers put out to the Hauliers , to make sure they would move the coal where and when needed. And Police trained in heavy-handed crowd control ( Southern Police only, so the Northern Police, couldn't tell their families).   If you want to know who put her in power look for  the 'Mayfair Set' & 'Great Britain 75', extreme right-wing zealots, who were preparing for a Military coup against a Labour Government.  Their plans were uncovered and closed down. So they changed tack & one of their Pals Wifes was pushed into power (Dennis Thatcher)

How exactly could Thatcher get the miners to strike?
