Elemore Colliery. The colliery was started in 1825 by the Hetton Coal Company on land owned by the Reverend Fox. Later owners were the Lambton and Hetton Collieries Ltd (1896), Lambton, Hetton and Joicey Collieries Ltd (1924) and National Coal Board (1947). The sinking was complicated by encounters with large "feeders" of water penetrating the shafts. It was worked from two shafts each with a single cylinder vertical winding engine which was used for pumping as well as winding. There were several pits - George Pit (1825), Isabella Pit (1825), Lady Pit, Caroline Pit, Jane Pit. Eventually the Caroline Pit was abandoned on the recommendations of Messrs Buddle and Hill in June 1832. The sinking of the Jane Pit was, however, more successful and the first coals were drawn in 1833. The workmen in these early years lived in houses built of sod at Low Downs. In the midst of Low Downs square existed a "Fad" where colliery horses were kept. On 2 December 1836 an explosion killed 28 men. It was caused by a firing of hydrogen gas accumulated by the leaving open of a trap door. There is a memorial to the victims at the church of St Michael and All Angels, Easington Lane (HER 5185). The Caroline shaft, abandoned during sinking because of the volume of water encountered was re-opened in 1853. A surface fire in 1867 caused the death of one man underground. The sinking of the New Pit or Lindsay Shaft started in 1870 the first coals being drawn in March 1874. The Jane and Caroline engine houses were erected in the autumn of 1880. In December 1895 3 men died from foul air in the colliery. In 1925 the Jane Pit was reopened. The pithead baths were erected at the colliery soon afterwards and were opened in 1930. After the Second World War the George shaft was deepened. In the mid-late 1950s the colliery became part of Hawthorn Combine Mine (near Murton). The mine closed in 1974 but in 1980 was earmarked for preservation, particularly as the Isabella winding house still stood with its engine still in situ, the only single cylinder vertical engine known to survive thus. Today sadly, only the pithead baths survive (HER 5109). 168 fatalities while operational.

North Hetton Colliery. The colliery was served by the Rainton and Seaham Railway North Hetton Branch, (HER 2305). Opened 1821 (or possibly 1825), closed 1935. 57 fatalities while open. Owned by the North Hetton Coal Company (Earl of Durham, Wood, Philipson, Burrell etc) in the 1850s and later by the Lambton and Hetton Collieries Ltd. Whellan reports in 1894 that daily output of coal was 360 tons. There were 320 workers and an associated firebrick works which made 60,000 bricks per week and a gas retort works. In Moorsley village, the colliery company built a Mission Chapel (of St Cuthbert's Church, East Rainton), a Wesleyan Methodist chapel and a Primitive Methodist chapel. A school was built in 1871 for 360 children.
