Abstract
The quality of a joint component connecting the winding rope and cage used in a shaft is concerned with human safety and coal production of the mine. According to regulations issued by the Chinese Ministry of Coal Mining, 'The joint must be replaced every five years and should not be used again unless it is proved to meet the safety requirement through non-destructive inspection. ' In order to make the replacement in the Cai Tun Coal Mine, batches of new joints have been produced. The results of ultrasonic inspection show that large amounts of internal defects are present in the new joints. This paper addresses the extent to which the defects can be tolerated under working conditions in the Cai Tun Mine.
