Colliery closures

[Wheldale]

Out of the 20 or so mines that were privatised, almost all have closed. Was this a result of bad management? Can it be put down to "bad conditions/geology" or have the private companies raped the industry for what they could?

[tygwyn]

Were there as many as that sold off?

Reasons for closure,i would suspect a variation of your list,but lying heavy on the latter reason.
