Anon, August 10, you must be blinkered and deluded.
For your information, Harold Wilson was given permission to close 252 pits by the NUM and the National Coal Board after consulting them.
Coal stocks in those mines had depleted, meaning they were uneconomical and had to close.
Most of the workforce were transferred to other collieries, others either took early retirement or found employment elsewhere.
Margaret Thatcher closed 154 pits for spite.
Get your facts right and get a life.
