Bilsthorpe Colliery Roof Collapse (1993)

A roof collapse caused by unsafe roof bolting killed three men nearly 2,000 feet underground as they drove a tunnel toward a new coal seam; an under-manager was posthumously awarded the George Medal for warning his colleagues.

Cause

Unsafe roof bolting, as found by a 1994 HM Inspectorate of Mines report.

What happened

On 18 August 1993, just before 11am, development workers at Bilsthorpe Colliery were driving a tunnel through to a new coal seam nearly 2,000 feet underground and four miles from the bottom of the shaft when the roof collapsed under some 7,000 tonnes of rock. Bill McCulloch, 26, of Rainworth, Peter Alcock, 50, and under-manager David Shelton, 31, of Blyth, were killed. Three other men -- Orest Kocij, Paul Smith and Russell Turner -- were trapped by the fallen rock but survived.
