Two-Stage Heading Machine for Fully Mechanized Driving of a Lateral of 5.3 Meters Diameter

摘要

Plans exist to drive a lateral of 1.6 km length and 5.3 m diameter as a ventilation road in the 1100-m horizon of the Consolidation Colliery in Gelsenkirchen (owned by Bergbau AG, Essen). The machine to be used is a heading machine manufactured by Maschinen- und Bohrgeraete-Fabrik Alfred Wirth and Co. KG, Erkelenz. Responsibility for driving the roadway has been assumed by a study group consisting of Gesteins- und Tiefbau GmbH, Essen Gebhardt and Koenig-Deutsche Schachtbau GmbH, Essen, and Murer AG, Erstfeld (Switzerland). The Wirth heading machine is 45 m long and weighs 200 tons. It is being used for the first time for bituminous coal mining in Germany. It consists of the TB II - 300 H full-face and pilot boring machine and of the TBE-II - 300/600 expander boring machine. (ERA citation 05:004005)
