An international review of the use and testing of the wire ropes used in mine hoisting

摘要

In early 2000, CANMET-MMSL was engaged by the Ontario Ministry of Labour (OMOL) to conduct an international study of the practices, in several key mining jurisdictions, of determining the criteria that are used to decide when the wire ropes used in mine hoisting are to be retired from service. Subsequently, the author visited key officials and institutions in Canada, the United States, the Republic of South Africa, the United Kingdom, Germany, and Poland. Material from the Australian province of New South Wales and Hungary was also included. The report that resulted included, among other sections: (I) the history of wire ropes and trends in manufacturing technology; (2) a review of mine hoisting practices; (3) the requirements regarding safety factors; (4) a review of the various operations and their potential future development; (5) the criteria for rope replacement; (6) potential future developments that could take place in 30th hoisting and rope inspection practices in Canada; and (7) recommendations. Subsequently, the report was issued by OMOL, and as a CD-ROM by CANMET-MMSL. In this paper the author presents the key findings and the recommendations made in the study.
