History of Northwich February 2004 a £28 million programme to stabilise the abandoned salt mines underneath Northwich was begun. The work was funded by the English Partnerships through its Land Stabilisation Programme, introduced to resolve issues associated with unstable mines around England.

When they were abandoned the mines were left with supporting salt pillars. Modern salt mining leaves around 30% of the salt to form the pillars but, because of the wild-brine pumping, the

The act of mining required different methods of extraction depending on the mineralogy, geology, and location of the resources. Characteristics such as mineral hardness, the mineral stratification, and access to that mineral will determine the method of extraction. Generally, mining is either done from the surface or underground. Mining can also occur with both surface and underground operations taking place on the same reserve. Mining activity varies as to what
