Abstract: According to the constuction needs of the large and extra large mine in the western region of china,and in orderto improve the automnation & iteligentlevel of 50 tons skip's loading.based on the existing shaf loading pattemns and usage a loading rogram withthe frt set measuring conveyor was poposed and its keytechnolgies were reseached.such as the whole structre.the key components chain spockets des ign.precision weighing and measuring devices automatic mode witha inteligent speed- regulation system of frequency conversion techncogy and others.The theoretical anaysi showed thatloading speed contioucus operaion and up 0 1.4 mn s,the loading time less than 4 s met the requirements of 50 tons skip's loading.These resuits lad the foundation for the prototyp tral and provided referenoe for the shaft loading system design of ten- million ton level mine.
