· Unlike rock mining, belt conveyor transportation systems have always been commonly used in continuous surface lignite mines. Though these mines are mostly located on a flat area, due to their depth and specific technological arrangements, there are various possibilities to convey large amounts of overburden downhill by declined conveyors.

 · Depending on an angle of a declined transportation route, there is a possibility to convert the potential gravitational energy of conveyed down overburden masses into electric energy. To recover the maximum percentage of stored energy, an energy-effective and fully loaded belt conveyor should work in a generator mode.

Standard troughed belt conveyors are comprised of conveyor belting that rides on heavy-duty troughed idlers. Idlers range in angles from 20°-45° and are securely mounted to a structural steel frame. INCLINED CONVEYORS These belt conveyors can be run at various inclined angles, typically between 0°- 20° (30° with cleated/chevron belting).

Depending on the application, the conveyors can reach lengths up to 100 km. The conveyor belts are exposed to high stresses caused by the bulk solids they carry and prevailing high tensile forces. Besides belt …
