Systems approach to improve utilisation of autonomous drilling at an open pit mine in South Africa

Abstract

Mining companies have opportunities to feed the continuously growing global economy. However, these opportunities come with challenges. Technologies like drilling automation can help combat these challenges while improving operational efficiency. Although the importance of investing in technology is well appreciated, mining houses still struggle with the sustainable and effective use of introduced technologies. This study looks at the challenges faced by one of the open pit mines in South Africa. The case study mine has introduced ADS (autonomous drilling system) to aid in improving both health and safety, and operational efficiency, but utilisation of the system remains low. The aim of this study is to investigate potential causes of the problem and to come up with an actionable solution to tackle the challenges faced and improve the use of ADS. Six semi-structured interviews were conducted where experts in the field of autonomous drilling shared their insights into factors affecting the adoption of ADS. The interview data were recorded, transcribed and analysed using thematic content analysis. The analysis of the interview data yields seven themes: stakeholder engagement and buy-in; management support and trust; process management and KPIs (key performance indicators); ownership, accountability and influence; site capability; culture and attitude shift; and implementation approach. Using the systems approach and soft systems methodologies (SSM), the study found that effective stakeholder engagement and communication with workers early in the project can lead to a positive attitude towards the introduced system, improving its adoption. Further, management support becomes vital to build trust and team resilience, especially during challenging times. Additionally, the way of managing processes must evolve and adapt to accommodate the technology system introduced, and this requires a mindset shift from a leadership perspective. Operating standards and procedures of the entire drilling process, from planning to execution, also need to evolve with the introduction of technology to ensure that upstream processes become enablers of the effective use of the technology. Like standards and procedures, key performance indicators are those metrics that managers track, and they also need to be updated to allow accountability and ownership around the use of technologies like ADS. With commitment and drive from operational leaders, technology implementation can succeed. The correct implementation approach will increase the chances of success. The approach must be guided by an effective stakeholder engagement and requirements analysis. A proper approach in tandem with both management support and team commitment can result in the sustainable adoption of new technologies, including ADS.
