A transport system was developed which allows personnel and material transport by trackless vehicles in the outbye area (max. 4 km distance from the shaft). The system comprises semi-trailer combinations (approx. 17 t payload) for the pit yard/shaft/pit bottom transport, material transport vehicles (payloads approx. 5 t and 8 t), and shield support transport vehicles (approx. 14 t payload). The vehicles may be run in roadways of > 3 m width and 2.6 m high including inclinations of up to 100 gon corresponds to 17%. Personnel transport is assured by mini-buses (10 seats) or buses with pivot-steering with 16 or 22 seats. The vehicles can also be used in in-seam roadways. Multi-purpose vehicles were not found to be useful. Mineral wastes transport from roadheading is out of question with present-day drive technology because of the large distances (> 7 km), the large quantities involved (> 1000 t/d), and because of excessive emissions from the exhausts. For level roads a practicable floor consolidation method was developed on the basis of concrete casting or mineral-blend techniques. An EDP-based transport model was developed for free-steered vehicle operation. (orig.) With 1 tab., 65 figs. (ERA citation 14:005792)
