0092…Harry Stoke Coal Mine

owlHISTORY OF STOKE GIFFORD
Edited by Adrian Kerton

 

Harry Stoke Coal Mine

There has been coal mining in the area for some time and in In the mid 1950s it was hoped that the Harry Stoke mine would have rejuvenated the coal industry in the area. Three seams were worked; the 5 Coals  seam, the Giller’s Inn seam and the Great Vein. By 1962 the mine had produced a total of about 465,000 tons of coal and had made a loss of just over £800,000. By the 1960s much of the Somerset coal field had been closed down and Harry stoke was now remote from them. Eventually the Coal Board made the decision that it would not risk putting more money into a venture that had not proved profitable and the mine closed on 14th June 1963. At this time the mine employed about 180 men. Some were relocated to other mines and pits in Somerset, however many of the surface workers were partially disabled from pit accidents, it being the Coal Board’s policy of trying to employ such men on the less demanding surface work and they were offered redundancy, pension and compensation. The Somerset coalfields shut down in 1973.

The land for the mine was sold by Wallscourt Farm on with a clause for buy back when the land was no longer needed. See this page for a difference between the farmer and the coal board.     0044j…Wallscourt Farm & Sale of Land for Harry Stoke Mine

Dear Sir,
We are now in receipt of your enquiry of 2nd May 1980, relating to the above, addressed to the Area Surveyor, Cardiff.

In consultation with Geological Survey, boreholes in this area in 1950/51 proved the Great Vein group of seams in the Lower Series, as a result of which two crossmeasure drifts, dipping 1 in 3.3, were driven through the Trias cover into the outcrop of the Gillers Inn Vein, from which the Great Vein and Lower Five Coals could be won by level crossmeasures.

The dipping crossmeasures, supported by 10’0” steel arches, contacted the base of the Trias at a distance of 310 metres, the initial drivages into the seams were completed, and ventilation established, to enable coal production to officially commence on 23rd August 1954.

The Great Vein, one of the principal seams in the Bristol Coalfield, was found to be variable and disturbed, so that working was severely limited, although some exploratory drivages were undertaken to prove conditions. Working concentrated initially in the Five Coals Seam, but this encountered disturbances. The Gillers Inn Vein was then worked within the limited area set by the faulting and other disturbances, and production ceased on 14th June 1963.

All three seams were bituminous coals, and the total saleable output from the mine amounted to nearly 485,000 tons.

The greatest area of work was in the Five Coals, which extended for some 900 metres to the dip, but only some 450 metres to the North and South of the drifts before faulting stopped production. Workings in the Great Vein and Gillers Inn Vein were contained within this area.

Boreholes in the immediate vicinity of the drifts proved Trias cover between 72 metres and 81 metres thick concealing the coal measures. Detailed logs of these three holes, and two others in the Harry Stoke area, are available if you wish to examine the detail.

Boreholes to the North of Harry Stoke, in the Stoke Gifford area, are also available. These indicated that the disturbed conditions proved at Harry Stoke extended into Stoke Gifford.

We trust that this will prove of assistance to you, and no doubt you will advise if you wish to examine the borehole logs.
