The Coal mine of Hasard de Cheratte 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.HistoryThis first shaft was dug in 1850 to a depth of 250 meters. After reviewing the mine to know its state, the engineers noticed that the thiny coal was located deeply. The first mine was dug again and reached a depth of 420 meters. The place on which the mine is located is not very big. The extraction company decided to build a headframe, a first in Belgium. This tower was fitted with an extraction machine and several motors working with direct current. A washhouse was built in 1920 by Beer de Jemeppe company, and a second extraction mine with a metallic tower opened. In 1927, the Belle-Fleur mine was equipped by a little tower made of reinforced concrete and a low power winch. Its work was to bring the tailings back to the surface.A third mine and a headframe were built between 1927 and 1947. In 1938, the mine reached 313 metres depth, but it only became operational in 1953. It was improved and reached 480 metres depth. The extraction machine at its top was insufficient. The engineer decide to install a machine on the floor, and to improve it. The n° 1 mine stopped the extraction and became a rescue mine. Then, its additional building were converted to showers and cloakrooms. The n° 2 mine was sealed off. In the 1930s, the site reached its apogee, employing 1 500 openers. When it closed on October 31, 1977, it employed more than 600 miners.
