Krakbau Spółka Akcyjna specialises in typical mining works. We executed these works with two methods: conventional technique (using explosives) and using the AM 105/045 heading machine. Miners from Krakbau S.A. were employed in the mines of Walsum, Ost-Hamm and Prosper-Haniel in Bottrop.
The gangways and dog headings created by Krakbau S.A. were of the arch shell type (sections: 21.0 m2 to 41.0 m2), and the wall surfaces were of the rectangular shell type (sections: 21.0 m2 to 23.0 m2).
