APPLICATION AREAS FOR MODERN BOOM-TYPE ROADHEADERS OF VARIOUS POWER CLASSES IN TUNNELLING. SECOND INTERNATIONAL TUNNELLING SYMPOSIUM, MUNICH, 12 APRIL 1989
This paper outlines the design features, classification, selection criteria and application areas for modern boom-type roadheaders, which are used mainly for tunnelling and in the mining industry. Their technology has developed rapidly in western Europe, leading to improved machine performance and adaptation to a variety of local, geological and technical conditions. Their design features are at present classified according to: (1) weight of the machine; (2) power installed in the cutting head and cutting capacity; (3) cutting range and profile cutting. The following features are important for optimising performance: (1) low centre of gravity; (2) optimal relationship between cutting head power and weight; (3) modular design; (4) low machine height; (5) compact design; (6) clear deck; (7) safe position for operator; (8) adaptability to various operational and geological conditions. The selection of the most suitable roadheader for a given job depends on its design features but even more on the tasks to be performed within a heading context as a whole and on the requirements to be met by special auxiliary equipment complementary to the machine. Roadheaders can be applied to building subway, road and railway tunnels, roadway headings in mines, construction of large cavern systems, and preparation of foundation pits and open-cast mines. The German title of this paper is as follows: "einsatzbereiche fuer moderne teilschnittmaschinen verschiedener leistungsklassen im tunnelbau". For the covering abstract of the conference see IRRD 824157.
