Abstract: EXPEKIMENTS AND STUDY ON AN ON-LINE MEASURING METHOD FOR ORE DISCHARGE CAPACITY IN THE LARGE ORE STORAGES Liu Yuanxiang;Wang Changhong（Dalian Applied Technique Institute, 116032）（Institute of Baotou Iron and Stell Corp., 0l4010）ABSTRACT A new on-line automatic method for ore discharge capacity through sliding canal in the largemetal ore storages is introduced． In this system ， the nuclear radiation measurement and the microelec-tric technique have been used to carry out ore discharge capacity in the space. Some experiments aredone. The basic principle ， experimental results and analyses are introduced. Key words automatic measuring method of ore dischrage capacity ore storages ore dischagethrouge the air
