Wheatley Hill Colliery inrush, 1871

In January 1871 a place being driven at Wheatley Hill Colliery to drain water from old Thornley workings holed unexpectedly into them, and the water drowned men working there. The coroner's jury found manslaughter against the chief viewer, resident viewer and overman, but the case collapsed at the Durham assizes.

Cause

An influx of water on unexpectedly holing into workings known to contain water; the plans did not match the ground.

Contributing factors

Front boreholes of three yards and flank holes of two yards, irregularly bored; on the night before, the left flank hole had not been put in.

What happened

The Original Hartlepool Collieries Company had reached the dip of its royalty at Wheatley Hill; its Thornley collieries lay to the rise, and a place was being driven to join a pair of old headways and free water from a detached part of Thornley. The plans showed an 80-yard face nearly at right angles to the advancing place, which would have made short boreholes enough; the ground was not as the plans showed, and the place holed into the water.

Rescue & recovery

Unknown.

Investigation & inquiry

The inspector, Mr Willis, wrote that boreholes should be six to eight yards long with flank holes no more than five yards apart, and at least ten yards where the plans were in doubt.

Legal & regulatory aftermath

The coroner's jury returned manslaughter against William Spencer, chief viewer, William Hay, resident viewer, and Thomas Watson, overman. At the March assizes at Durham the grand jury threw out the bill; Baron Martin let the prosecution proceed on the inquisition, found 'no shadow of a case', and the prosecution was withdrawn.

Changes to practice & legislation

Willis's recommended borehole lengths and spacing for approaching old workings.

Memorials & commemoration

Unknown.
