The proposed standard will encompass the inspection and maintenance of underground mine structures, including; • mine shafts and, • associated underground mine installations. (it is not intended that this standard be applied to surface structures such as the headframe). It is intended to provide practical guidelines to assist plant maintenance personnel with the following in respect of the mine structures: i. What should be inspected and monitored? ii. How should inspection and monitoring be accomplished? iii. At what intervals should inspections and monitoring be done? iv. What should be recorded and when? v. What should be expected in an inspection report? vi. What follow-up is required? It is not intended that the proposed standard be used for certification purposes. No guidance is provided for the design or construction of plant structures. In addition, it is not intended to provide guidance as for pressure vessel or similar systems.
