Overview
The group of pits around Dearham, near Maryport, worked from at least the 1830s, where five people died when a winding rope broke in 1844; the main seams were abandoned as unprofitable in 1894 and the last in 1932.
History
Dearham Colliery is the name under which the many pits around Dearham, near Maryport, were recorded: the Folly, Lonsdale and Lowther pits, and on the plans the Croft, Hope, Parkin, William, Wright, Scott and Outgang pits among others. Coal made the village: its population grew from 515 in 1821 to 2,598 in 1891. Deaths at the pits are recorded from 1837, and the Crow seam was abandoned in 1863.
On 24 August 1844, at the pit of Ostle and Dunglinson, two men and three boys were being lowered together when the rope broke a few feet from the top, and all five fell about fifty yards to the bottom of the shaft. The youngest was eight. A report that the rope had been cut was examined at the inquest, which sat until midnight and found that it had failed through bad material.
John and Thomas Walker owned the colliery in the 1860s and John Osmaston in the 1880s, followed by his mortgagees. Thomas Dacres, or Dakers, was manager for most of the 1880s, when the Folly and Lonsdale pits were raising coal and fireclay. In June 1894 the Ten Quarter, Rattler, Metal, Cannel, Yard and Little Main seams and the fireclay were abandoned as not profitable, while 26 men were preparing to sink anew. A last set of seams, including the Lickbank, was abandoned in 1932.
