“…Consequently, many scholars have further studied and improved the Stability Chart. Several variant charts like Potvin (1988), Nickson et al (2001), etc., have been developed [61][62][63][64][65]76,77]. The Stability Chart is widely employed and valued in the mining industry for guiding the design of underground excavations in deep hard-rock metal mines.…”

A reliable design of stopes is critical to ensure both safety and efficiency in mining operations. The evolving mining methods and technologies as well as increasing mining depth dictate the need to continually improve stope designs. This paper presents a comprehensive review in order to compare and consolidate various stope design methods. This review covers various aspects of stope design, including design principles, factors to consider, and the diverse range of design methods available. The results led to the classification of various methods encompassing engineering analogies, fundamentals, numerical simulations, and industrial tests. Of particular significance, the review furnishes detailed insights into the research conducted on each method, as well as each method’s practical performance in engineering applications. Furthermore, the review highlights the inherent limitations in current design methods and suggests potential avenues for future research. Finally, by comprehensively considering the functional roles and advantages of each design method, it overcomes the limitations of relying solely on a single method for stope structural parameter design, and a general process is proposed.

“…Villaescusa et al (2006) investigated the performance of resin rebar bolts through overcoring testing and found variability in load transfer along the length of individual bolts as a result of variable quality of resin mix along the length of the bolts. Potvin et al (1999) discussed the difficulties in controlling the quality of the resin rebar bolts that resulted in ground falls at the Mount Isa Mine. Controlled field testing prior to full-scale bolting campaign and utilisation of standard installation procedures were recommended to improve the consistency of resin rebar bolt performances.…”

When designing ground support systems for a mining environment, the interpretation of technical specifications and the expected quality of installation must always be considered. These design considerations are easier to assess in an operating mine but are more difficult to gauge at an early stage of a new project. This paper is a case study on resin rebar design and installation as part of a fall of ground rehabilitation at an underground mine. The paper is focused on the design, testing, implementation, and installation of resin rebar as part of the primary ground support design. This includes the steps taken to go from a set of technical specifications to a functioning operating procedure based on the actual conditions and factors influencing the successful installation of resin rebar bolts. The operating procedures are closely related to installation equipment, in this case mechanised bolters and jackleg bolters. Quality assurance and quality control of the resin rebar installation to monitor installation quality and detect changes in the conditions are also discussed. Sample test results are presented to demonstrate possible installation and testing pitfalls.
