Challenges in shaft logistics in mining and tunnelling / Herausforderungen in der Schachtlogistik im Berg- und Tunnelbau

The article deals with the logistic challenge of supplying large quantities of construction materials underground. In this regard, the necessity and problems, which led to the development of introduction of pneumatic and hydraulic conveyance systems for construction materials in German coal mining, are described. Additionally, the various intermediate stages of development are described up to the techniques used today. The advantages and disadvantages of pneumatic conveyance of dry materials and hydraulic conveyance are described. The technology in use today is the result of a history of research and development over more than 40 years and above all the demands of the mining industry. The material is distributed below ground through a network of pipelines and intermediate stations. The various galleries and bottoms can be reached through pipe switches. The control and operation of the above-ground system, the intermediate stations and the pipe switches is automatic and unmanned. The entire construction material supply network is controlled and monitored by the OPC server situated above ground. The data can easily be forwarded to downstream monitoring positions or connected for remote maintenance which is common practice today.
