RWE Power operate the Inden opencast mine with the output of Brown Coal going to their nearby power station. The Inden mine in the Aachen City Region extends from the municipality of Aldenhoven and the A 44 (Düsseldorf-Aachen) motorway in the north to the A 4 (Cologne-Aachen) motorway in the south. In 2017 there were reserves of 260 million tonnes with output capacity of 20 million tonnes per annum. This is one of five spreaders in use on the site which have a total capacity of 110,000 cubic metres of material per day.

The Bilstermühler Straße limekiln south of Krauthausen was built around the end of the 19th century as a free-standing shaft kiln made of quarry stone masonry on a square base. It has two draw tunnels for removing the lime and achieved a daily output of around 30 tons. At some point the stonework was reinforced by concrete banding. The kiln became disused in the 1950s and in 1987 was restored by the RWTH Geological Institute. It is subject to a preservation order.

In 1784 Johann Peter Wültgens extended the coal concessions he had in the area of Eschweiler near Aachen. In 1794 a Newcomen type pumping engine was erected on the colliery which is described as driving 2 pumps with 42m of rods. It worked at 11-12 1.76m strokes per minute. It was one of the earliest steam engines in Germany. The enginehouse survives and is rather different from the normal British practice where the beam pivoted on an outer wall and the shaft was outside the building. In this case it looks as if the engine was entirely within the building.

This limekiln at Hahn near Aachen was built in 1924 by the firm Schornstein und Drisch. The works was later operated by Gilles das Kalkwerk and this draw kiln produced 30 tons of lime per day. The kiln was restored in 1987 and is an important local historical monument.
