According to geology situation such as ups and downs of roadway layout and the working environment in more than 1 000 m deep shaft,  computation basis, load pickup and system design process of selection principles were put forward. The production capacity of belt conveyor transmission was checked. The results proved that designing of belt conveyor system conformed to the related provisions on Coal Mine Safety Regulations, transmission capacity of belt conveyor 1 102.68 t/h is less than the nominal transmission capacity 1 200 t/h, and it can meet the demand of the mine production capacity.
