【正文】 gned this time is mainly used for transporting the coal at a short distance in the coal mine roadway underground. The design process strictly follow the general des ign principles of the belt conveyor. At first, it is a simple introduction about the belt conveyor. Next, it is an analysis of the belt conveyor selection principles an d calculation methods. After that, according to the material features and working conditions given, the whole structure of the belt conveyor was determined. Then it is the calculation and strength checking about selecting driving device and the main ponents in the conveyor. The circumference driving force of the drive roller、 the tensioning type and the amount of tensioning force were also deter mined . The ordinary belt conveyor consists of six main parts: Drive Unit Work ing part、 Delivery End、 Intermediate Structure、 Loop TakeUp and Belt. As a result of underground working environment and the plexity of equipment operating conditions, it is necessary to consider every kind of possible working conditions during its design and calculate the parameters in the most dangerous condition,take corresponding measures to provide an effective guarantee for the normal and reliable transport of the belt conveyor.
