Well said Cyril,but the strange thing is,we are burning more coal for electricity generation now,than we were 10yrs ago,read the other day,40% of electricity comes from coal generation,makes one wonder why they keep erecting these wind turbines.
Your mates might have had better job security if Flack had continued working the Colliery,Riche Mining as far as i know,came on the scene a few years back,when they purchased the Johnson Colliery,Blaenafon,Nr Abergavenny,with their head office in the Virgin Islands,owned by a Chinese gentleman,last year they bought into Dan y graig No.4,Crynant ,Nr Neath,also in South Wales,which is still developing,driving through the gobs,that i worked in the late 70`s early 80`s.
What i heard ,after they purchased Hayroyds they had a big fall on the drifts,if that is true,and since ,no further work carried on,your mates would know for sure the main reason for closure.
They have also closed the Johnson Colliery.
