Which was halted by a natural disaster, Camlaren Mine or Barton Mine?
Barton Mine Barton Mine, also known as Net Lake Mine, is an abandoned surface and underground mine in Northeastern Ontario, Canada. It is located about 0.50 km north of the Temagami Arena in Temagami North and just east of the Ontario Northland Railway in northwestern Strathy Township. Dating back to the early 1900s, it is one of the oldest mines in Temagami. Barton was the site of a fire in the early 1900s, after which it never had active mining again.
Coal mine of Hasard de Cheratte The Coal mine of Hasard de Cheratte (or Cheratte 10) is the main colliery of Société anonyme des Charbonnages du Hasard, composed of four mine shafts. It is located in Cheratte, a section of the Belgian town of Visé located in the Walloon Region in the province of Liège. The first well was dug in 1850 to extract dice coal and closed for the first time in 1877 following an accident. It re-opened thirty years later in 1907 and operated until 1977. In the early twenty-first century, the mine has gained some notoriety as an urban ruin. Remediation of the site and the demolition of several buildings start in 2017.
