Calverton was closed by British Coal in 1993 and reopened by R.J.B the following year. Since then,the mine has produced over 2.5 million tonnes of coal. But R.J.B announced today that deteriorating geological conditions in the limited remaining accessible reserves, leading to higher production costs, have made "ongoing operations unviable, both now and in the forseeable future." Production at Calverton,will cease next week. About 40 men will be retained to secure the underground areas and recover items of equipment, and about 100 will be offered transfers to other R.J.B mines. Redundant employees will receive severance payments based on their earnings and years of service, as well as three months' pay in respect of the statutory 90-day consultation period. Richard Budge, R.J.B's Chief Executive, said: "Given the dedication and effort that everyone has made, we are disappointed that we have been unable to maintain operations for a longer period. We can only hope that the commitment our employees have shown will encourage new employers to take advantage of their undoubted skills."
Some 25-30 million tons of coal remained in the ground at Calverton.
Three hundred jobs were lost although, reflecting an ever more mobile population, only around 40 miners lived in Calverton by this point.
A documentary was made about the miners plight. It was filmed on location at Calverton. Warning, these are miners working in extreme conditions so do not enter if swearing easily offends you. (This site is not responsible for items on external websites)
