HS2 Salt Mine Route Fears


Yes, salt mines, of course this comes as no surprise if you live in Cheshire but it might be if you do not know the area. Parts of Cheshire have been known for their salt since Roman times and mining continues to this day. Past extraction pumping hot water through the mines dissolved the salt and the resultant brine was pumped out and the salt extracted from the brine, this has left vast caverns and led to land subsidence as mines collapsed.

The New Civil Engineer reports:

“… MPs fear spiralling costs due to the complexities of building over the land and future problems with subsidence when the line passes over the area riddled with old salt mines…

Conservative MP for Eddisbury Antoinette Sandbach said a “deep worry” was that HS2 did not seem to be disclosing the “appropriate” level of technical reports which would allow experts to give their opinion on the scheme…


… rail minister Paul Maynard said HS2 had commissioned a specialist mining engineer to undertake a study into the section of the route. The study is being carried out in consultation with the Cheshire Brine Subsidence Compensation Board, using existing data from organisations such as the British Geological Survey, the salt industry and local authorities.”

It all goes to underline the importance of knowing what are the right questions to be asking when it comes to buying land.
