Conservatives closed 160 mines
Labour closed 290 mines.
Well, actually..
Since WW2:
Labour closed a total of 371 deep mines
Conservatives closed a total of 584 deep mines
Coalition govt closed 2
The salient point about Thatcher's closures is that they were a greater percentage of the total mines operating in the UK and they put more people out of work than did previous Labour closures.
According to the National Archive (not, I think, a biased source) many mines that were uneconomical or nearing being worked out, were kept going until the 60s because there was actually a national shortage of coal. As other fuel sources (oil and gas) became more widely available of course many mines were closed. MacMillan closed 246 deep mines...
And many closures were of worked out small mines. The Durham coalfield, where I live, is covered with mining settlements (or completely obliterated settlements) where the mines were worked out and closed over the 60s and 70s. Hard to get indignant about the closure of worked out mines...
While Thatcher was busy closing the deep mines and miners losing their jobs, the UK was importing coal from eastern Europe, notably Poland, so her motives were as much political (1984 Miners' Strike, anyone?) as practical.
Quoting figures proves very little unless the context is understood.
Comprehensive figures here. These 'nerd' type websites are usually very well researched.
