The Galilei mine is a former non-ferrous metal ore mine in the Bensberg ore district in Bergisch Gladbach in the Frankenforst district . The main operating point was about 1000 m south of the Federal Highway Research Institute on the so-called Bergmannspfad.

history

Remnants of the spoil heaps (2011)

The Consolidated Galilei mine field was created from the individual fields Galilei, Bensberg and pencil. The original Galilei mine was first awarded on March 10, 1855 under the name Antonie auf Galmei . An extension of the award of the mining property was carried out on August 22, 1868 Lead - zinc - and copper ores named Galileo. The Bensberg mine (originally Mutung Georgei) was initially awarded as the Garibaldi mine on May 15, 1861, before an extension was awarded on August 20, 1868 with the name Bensberg for reasons that are no longer comprehensible today. Lead and zinc ore were extracted here. The pencil pit (originally Mutung Davy), which was first awarded on June 11, 1859 under the name of springtime, was extended on August 25, 1868 under the name of pencil. The mining right granted related to lead, zinc and copper ores. All three mines were united with a certificate of consolidation dated September 6, 1889.

Operation and facilities

A few references give a very poor picture of the operations of the Galilei mine. The ore was extracted exclusively in underground mining via shafts , because the area around was so flat that tunnels could not be built. In addition, there was very little lead ore in the deposit . These are certainly the reasons why, in contrast to all other mines in the vicinity of Bensberg, no traces of old mining were found in the Galilei mine . Was reached on the western vein over a length of about 130 m over three Bausohlen a depth of 62 m. The extraction shaft was operated with a horse peg. The company buildings, machines and systems must have been primitive and dilapidated, as can be seen from later auction documents. Since there was not enough water available on the surface for washing , the water pumped out of the shaft was used for this. Between 1854 and 1863, a total of 116,849 quintals of zinc ore and 2,683 quintals of lead ore were mined. An average of 90 workers were employed.

The company was said to have ceased in 1863 "after the dismantling of the prepared ore materials due to external conditions" . It can therefore be assumed that experimental work was carried out here and there in later years. In any case, nothing is known of a renewed operation. The Bensberg and Pencil pits have probably not got beyond the stage of experimental mining.
