The tender seeks a service provider to develop pre-tensioning guidelines for Anti-Spin (ASP) cable bolts in various rock mass conditions. The project includes literature reviews, laboratory tests, and field trials to enhance mine safety.
This tender invites qualified service providers to undertake a comprehensive research project aimed at developing practical pre-tensioning guidelines for Anti-Spin (ASP) cable bolts used in the South African mining industry. The project will involve a thorough national and international literature review on existing pre-tension practices, characterization of common rock mass types using established systems, and the execution of laboratory pull-out and shear tests. Additionally, field trials will be conducted across at least three different underground mining operations to gather in-situ data on the performance of ASP cable bolts under various pre-tension levels.
The successful service provider will be responsible for analyzing the correlation between rock mass conditions and required pre-tensioning to ensure optimal performance of cable bolts. The outcome of this research is expected to significantly improve ground control practices, reduce ground-failure incidents, and enhance overall mine health and safety outcomes. By developing a structured framework for pre-tensioning based on empirical data, this project aims to fill existing gaps in the current guidelines and contribute to the advancement of safety standards in the mining sector.
This tender is suitable for research institutions, engineering firms, and consulting companies with expertise in rock mechanics, mining safety, and geotechnical engineering. Businesses with a proven track record in applied research and relevant experience in the mining sector are encouraged to apply.
