Long Work Pit

The shaft intercepted the Upper Four Feet seam at 158 yards and was sunk to the Lower Four Feet seam at 286 yards. This pit also incorporated a ventilation furnace which was located on pit bottom.The resultant convection currents caused by the flue gasses caused air to be circulated through the workings.

A report dated 10 July 1863 compiled by a W Jenkins, advises that the average length of underground haulages was 77 chains. However, this was revised in a letter dated 21 August 1863 such that the average length of haulage from pit bottom to the collier’s working faces was 109 chains.

Another D.I.C report dated 21 August 1863 advises that the vertical height of the pit was 156 yards (468 feet)and the vertical height of the drift was 70 yards (210 feet)  giving a total height of 226 yards (678 feet).

Coal Production

Colliery Reports 1894, 1895 & 1896

The seams worked were the Top Coal and Lower Four Feet.

The 1894 report stated that the Lower Four Feet seam was worked out and the pit was ventilated by a furnace but this would be removed once the fan at the North Tunnel pit was commissioned since this would also ventilate the Long Work pit.
