The opencast mine annually produces a spoil amount of 250 to 300 million m³. The ratio of overburden to coal is 6.2:1. The extracted lignite is transported via the Hambach industrial spur to Bergheim - Auenheim and from there transported via the North-South industrial spur to the power stations Niederaussem, Neurath, Frimmersdorf and Goldenberg near Hürth-Knapsack. The overburden was until 16 April 2009 partially transported by conveyor belt to the Bergheim mine, which has run out of coal and therefore been refilled and recultivated. The visible mark of the open pit is the Sophienhöhe spoil tip, which is considered to be the largest man-made hill, towering over the flat landscape by 200 metres.
