Transport and handling of construction materials in the hard coal mining industry and tunnel construction

摘要

In the German hard coal mining industry construction materials with the most diverse compositions are required for various applications. The largest proportion of the materials is required for the construction of roadside packs and for the backfilling of roadways because of the ever increasing depths and the resulting rock mechanical problems. Over the last 30 years handling, transport and processing systems have been developed to cope with these quantities of materials and to avoid further loads on the shaft hoisting installation. Nowadays these systems are standardised and are characterised by mobility, flexibility, small space requirement and the latest control engineering. This applies in partkular to pneumatic and hydraulic transport and distribution of the construction materials, in future ail mines will monitor and control all installations above and beiow ground from a central control room. The methods developed in the mining industry are also successfully used in tunnel and underground railway construction.
