Drill and Blast Guideline
Optimising Drill and Blast Practices for Improved Safety and Productivity in South African Mining
For over 120 years, large-scale mining in South Africa has primarily relied on drill and blast operations as the most economically viable and productive method for ore extraction. This process, although effective, consists of multiple interdependent steps that must be executed and repeated consistently to meet production targets. Despite advances in mining technology, the core drill and blast methodology has remained largely unchanged.
In recent years, however, the effectiveness and efficiency of the drill and blast cycle have come under increased scrutiny. It is now widely recognised that the quality of drilling and blasting has a direct impact not only on production performance, but also on the geotechnical stability of underground working areas. Poor execution can result in unsafe ground conditions, increased operational delays and elevated safety risks.
This concern is particularly relevant given the continued prevalence of Fall of Ground (FoG) incidents in the mining sector. In response, the Minerals Council South Africa (MCSA), through its Mining Industry Occupational Safety and Health (MOSH) Learning Hub, has prioritised improvements in this area. Specifically, the MOSH Falls of Ground (FoG) Team has undertaken the development of a Drill and Blast Reference Guide.
This guide aims to support the industry by identifying, documenting and promoting leading practices that enhance both the safety and productivity of drill and blast operations. By addressing critical elements in the drill and blast process, the initiative seeks to reduce FoG-related risks, optimise ore recovery and contribute to the broader mining industry's journey toward Zero Harm.
