Settlement sensitive structures over mines

[piler10]

Does anyone know of any settlement sensitive structures such as powerplants, semiconductor FABS etc that have been successfully constructed over areas of deep longwall mining?

Cant give you specific locations but theres probably dozens in England alone. Settlement after a long wall extraction is a very well understood phenomemon

Miningman, thanks for your reply. I don't have a particular geographical area of interest.I want to find out if this has been carried out successfully before. I know that there are some powerstations in Yorkshire built in mining areas, but I don't know if they are built on or only adjacent to areas of mining. I'm assuming this has been done before in South Africa if anyone knows of any examples?

piler10,

Do the terms 'deep' and 'longwall' go together? If so, would you expect any settlement?

You might try searching for the term 'subsidence' as one of your keywords.

While not a longwall operation, I seem to recall hearing about subsidence in the town of Flin Flon, Manitoba (Canada) when I was there a number of years ago. The mine underneath the town was creating building settlement issues (not sure if it affected the mill, etc.).

Cheers,

CanuckMiner,
Longwall can be carried out at depths of 700m. The reason I'm asking this is that I wouldn't expect much settlement from deep mines but I am interested in finding out if there have been any problems from deep mining. Thanks for your information on Flin Flon, I will search it.
