Calamity Mine, Mine train roller coaster at Walibi Belgium, Belgium.

Calamity Mine is a mine-themed roller coaster at Walibi Belgium that travels through a winding path with artificial tunnels and steep sections. The ride features a brown track that curves around the park landscape, taking riders on ups and downs throughout its route.

Opened in 1992 as Colorado, the ride was built by Vekoma on one hectare of Grand Canyon-inspired scenery with waterfalls and caves, at a cost of 250 million Belgian francs, then the park's largest investment. In 1998 the Pancho Villa area became Lucky Luke City and the coaster was renamed Calamity Mine after Calamity Jane, the character René Goscinny introduced to Lucky Luke in 1958. It was renovated in 2007-2008.

The 1998 rename ties the ride to Lucky Luke: the coaster is named after Calamity Jane, a character René Goscinny brought into the comic series in 1958, inspired by the real Martha Jane Cannary. The surrounding area became Lucky Luke City, replacing the earlier Pancho Villa zone.

The circuit runs 785 m with a top speed near 50 km/h and a maximum height of 14 m, reached on two covered lifts of 12 m and 14 m set side by side. Three trains of five cars carry 26 riders each, about 1,600 people per hour. A platform built above the station lets non-riders watch the trains pass.
