Asfordby (North West Leicestershire) Closed After 2 Years
- Continued -
Seams worked: The Deep Main, an unknown hybrid combination seam of part Deep Soft and Deep Hard coal 9’ 8” (2.94m) was worked, abandoned 18/8/1997. Other seams were accessed. Over 4,045 yards (3,700m) of roadway drifting, around 547 yards (500m) of Yard seam drivage, 656 yards (600m) of Blackshale seam drivage, around 10,390 yards (9,500m) of Parkgate seam 10’ 3” (3.12m) drivage (abandoned 8/12/1997) and over 43,745 yards (40,000m) of Deep Main seam drivage was excavated up to closure. At the DC pit bottom work began in the Blackshale seam in Aug 1988 and at the UC pit bottom in the Yard seam in Feb 1988.
The 2 shafts were 24 feet (7.31m) dia with 170 feet (52m) high winding towers (finished in 16 weeks), to accept a 25 tonnes skip and 1,600hp fan. Site work had begun in 1984 and sinking began at No2 UC shaft Aug 1987. The freeze chamber was from 317 yards to 444 yards (290m to 406m). The Permo-Trias measures 306 yards (280m).
The Upcast shaft, co-ordinates E 472512 N 320593 pit bottom, was in the Yard seam horizon at 481 yards (440m), shaft depth 532.5 yards (487m), with a steep drift down to Parkgate and Blackshale. Deep Main 368.6 yards (337.1m), Parkgate 392.5 yards (358.9m), Blackshale 425.9 yards (389.4m), Inset 426.9 yards (390.4m), sump 464.7 yards (424.9m).
Unfortunately the shaft was sunk onto an extremely hard volcanic rock plug which proved impossible to bore and fire therefore the shaft was finished at this level and so the proposed level pit bottom area for loco transport could not materialise! Number one hiccough! The Downcast pit bottom E 472548 N 320686, Blackshale seam horizon at 399.8 yards (365.6m), Inset 382.7 yards (350.0m), Parkgate 369 yards (337.5m), Deep Main level 346 yards (316.4m). Again, the simple sinking of boreholes on the shaft sites would have proved the strata.
A similar mistake had been made at Bevercotes, where in that case the target seam was washed out requiring the shafts to be sunk deeper. At Cotgrave where the strata at the Deep Soft horizon was not conducive with stability for a pit bottom and a new one had to made at Deep Hard horizon some metres below. It would appear that quite a few of the pits sunk after nationalisation would never be 100% successful.
West Parkgate drivage had a Continuous Miner with roof bolting, started 19/12/1989. North Parkgate drivage started Feb 1990. Shuttle cars were used for removal of material. Development of the mine had been by the ladder system. However several heatings were experienced.
The work pattern of 6 day working was 3 weeks of 6 day working then have one week off known as the Asfordby Culture. There were teams of 5 miners, plus 1 electrician and 1 fitter to undertake Reg 11 duties. The craftsmen were trained to drive shuttle cars and other equipment to give job rotation. Middle management was in charge on all 4 shifts. Later the traditional post of Undermanager was dispensed with and the job was undertaken by the Deputy Manager (by Law only classed as an Undermanager anyway).
The largest underground vertical bunker in the UK was the 34’ 6” (10.5m) finished internal dia 10 feet (3m) larger than anything before, 43.75 yards (40m) deep to hold 3,000 tonnes. Lining was done by spraying a quick drying concrete onto the wall as conventional methods were not possible.
Based on a 6 day working week 6 pit records were achieved in November 1992.
- 1,379m cut in 4 weeks
- 69m of in seam drivage in one day
- 108m in 101s main gate
- 123m in 101s tail gate
- 17,037 tonnes of ROM (run of mine material)
- 4,080 tonnes in a day through the new-concept Larcodems coal preparation plant.
The Mechanical Engineer devised a free steered people carrier, shown in the photo to transport men along the hundreds of yards (metres) of roadways driven. Pit designed materials pods are unique and used for carrying mesh, firefighting equipment, water bowser for dust suppression and stone dust spreading.
The first retreat coalface 101s in the Deep Main at 284 yards (260m) long started 25th March 1995 but after 612 yards (560m) of working was stopped due to adverse conditions and water on 5th January 1996. A change of policy dictated that short wall retreat faces 76.5 yards 70m long would be worked instead it was re-headed out and the first one 102sC short-life face started 24th August 1996 and worked 984 yards (900m) outbye until 31st March 1997. A second 76.5 yards (70m) long face 102sB was begun on 16th November 1996 and finished on 16th August 1997 after 1,640 yards (1,500m) retreat working. The first 284 yards (260m) long face 101s C1 was re-headed at a few hundred yards (metres) outbye and restarted 28th June 1997 but after only 153 yards (140m) the working was flooded when water rushed in from the overlying strata and the panel was stopped on 26th July 1997 and ventilation cut off. A water dam to withstand a pressure of 4.1 Newtons/mm2 was built near to the pit bottom in Nov 1996. There were 2 staple pits, one being a vertical bunker 55 yards (50m) deep and the other about 31 yards (29m) deep.

Jack Jones the Moderate NUM leader had warned of the danger of ‘slamming the door’ on 6-day working, as he said it could backfire on the union. Roy Lynk was the General Secretary of the UDM but by January 1989 he had been replaced by John Liptrott.

Fatal Accidents Asfordby: only one underground
- Charlie Place (late 20s / early 30s?), a Conveyor Belt man. A FSV machine (free steered vehicle) rolled over and pinned him. He left a wife and 4 children. The scene of the accident is shown in the photograph. On this occasion a member of the police force accompanied the HMI Bob Leeming to the scene but was told that he could not interfere until the site had been examined by himself and measured up by the surveyor because underground accidents come under jurisdiction of HM inspectorate unless foul play suggested. Police had to be shown how to use self rescuer.
Drifts At Calverton Put On Hold
Also in August 1997, the proposed drifts down to the Blackshale seam at Calverton were put on hold, due to the insecurity of the market. The pit was working areas of Top Hard and High Hazles seams.
Thoresby To Work Ollerton Reserves
The development headings at Thoresby (Nottinghamshire), projected to enter the old workings to work reserves left in the Parkgate seam at Ollerton colliery, when that Colliery was closed in February 1994, were also put on hold and 50 contractors were made redundant in October.
New Chief Executive
Kenneth Ferguson was chosen to be the new Chief Executive for the Coal Authority during 1997 and succeeded when Neville Washington stood down.
Coal Investments Went Under
In September 1997, Coal Investments went bust, with debts of over 60m from their 5 mines.
Proposed Workings Under Newstead Abbey
Midland Mining announced in October that they wished to extract 1.5m tonnes of Blackshale coal from underneath Newstead Abbey, from the Annesley Bentinck mine. This caused furore from local residents, the public and the Byron Society. The proposal could never go ahead.
Annual output for RJB Mining 1997: Asfordby 731,000 tonnes, 469 men; Bilsthorpe 432,340 tonnes, 105 men; Calverton 631,350 tonnes, 350 men; Clipstone 439,800 tonnes, 298 men; Harworth 1,761,900 tonnes, 674 men; Thoresby 1,980,000 tonnes, 602 men; Welbeck 1,440,500 tonnes, 628 men.

Jobs To Go At Clipstone
RJB Mining announced at the beginning of December 1997 that 78 jobs were to go at Clipstone (Nottinghamshire) immediately, giving rise to fears about possible job losses at Calverton, Thoresby and Welbeck
Bob Leeming appointed HM Senior District Inspector of Mines and Quarries and Rob Stevenson (10121) HM Principal District Inspector.
Department Of Trade And Industry Takes Over
On 31st December 1997, British Coal that started out as the National Coal Board, in 1946, operating from 1st January 1947 was disbanded. Any outstanding duties were transferred to the Department of Trade and Industry. Eastwood Hall that had started as a Mansion for George Walker of Barber Walker and Co fame was evacuated at that time.
