| Summary: | For complicated process and low efficiency of current truck loading in coal mine，a design scheme of self-service truck loading system in coal mine was proposed on the basis of operation mode of self-service petrol station. Structure of existing truck loading station of coal mine is optimized, namely light scale, heavy scale and truck loading station are integrated, and some equipments inside the station are streamlined, so as to reduce construction cost of the system. Self-service truck loading is realized by use of key technologies of one key starting and stopping for feeding system, parking space discrimination, wireless remote-control loading, etc. The application results show that work flow of the system is reduced to one from three, construction cost is reduced to 6.5×106 yuan from 8×106 yuan, time consumption is reduced to 60 s from 270 s, the number of operators is reduced to 3 from 18, and production capacity is increased to 2 300 t/h from 1 000 t/h. The system achieves a goal of cutting staff and increasing efficiency.
