A set of 100 accident reports from the mine were analysed using an existing framework that is based on Mark III of the Swiss Cheese Model, Incident Cause Analysis, safety management principles and the Nertney Wheel. The study revealed that routine violation (with 38%) was the most prominent form of unsafe acts whereas the most prominent workplace factor identified was behavioural environment (25.8% of all accidents analysed). The most common systemic factors identified as contributing to accidents were leadership (22.6% of all accidents analysed) and hazard identification (21.7% of all accidents analysed). The study also recognized physical environment as the second highest workplace factor (23.4% of all accidents analysed). Further analysis to indicate which systemic factors were linked to workplace factors shows physical and environment problems, fitfor purpose equipment and competent people. When systemic factors were linked to physical environment, the problems recognized involved management of change, work schedule, maintenance management and housekeeping. When systemic factors were when linked to behavioural environment, the most common problems identified were leadership, hazard identification and contractor management. Management of change, work schedule, maintenance management and housekeeping were recognized to be prominent when systemic factors were linked to unsafe work practices, whereas when systemic factors when were linked to competent people, leadership, hazard identification, design and training and competence were identified as the major problems involved. Finally, when systemic factors were linked to fit-for purpose equipment the most identified factors causing accidents were risk management, hazard identification, provision of resources, maintenance management, leadership and design. The outcome of this study demonstrates how systemic factors, workplace factors and violations contribute to accidents.

The geotechnical design parameters play a crucial role in shaping the method's economic feasibility and ensuring safe extraction practices, all while considering the unique geological conditions present at the site. These parameters are input into advanced numerical modelling software to enhance understanding and predictive capabilities, specifically, the Phase 2D program developed by RocScience, which facilitates detailed stress analysis. With this, a comprehensive stability assessment is executed using the renowned Norwegian Geological Institute Q (NGI) system). This empirical methodology provides robust insights into ground stability. The design of this mining approach is particularly significant, as it intricately involves various factors such as the dimensions and configurations of both primary and secondary stopes, the natural formation of the orebody, the properties of the backfill material, the compressive strength of the CRF, and the sequencing of the stoping process. Each of these elements plays a vital role in the overall effectiveness and safety of the mining operation highlighting the importance of meticulous planning and analysis in successfully implementing this method.

The geotechnical design parameters considered will make the method to be economical and safe for extraction, bearing in mind the prevailing ground condition of the mine. These have possible to arrive at the numerical modelling using roc science stress analysis program called Phase 2D. The stability assessment was conducted using the empirical method called the Norwegian Geological Institute Q system (NGI Q system). The viability of this mining method will depend on the size of the primary and secondary stopes, inherent orebody formation, characteristics of the backfill material, strength of CRF and stoping sequence.
