A critical look at local mining case studies the need to appreciate the men’s challenges monitoring programmes. in excavations or rather excavation designs He emphasised on monitoring being posed by rock mass variability. He revealed that the main pivotal parameter in ensuring the rock is such a challenging media to work preparedness and to prove the point he with than concrete hence why they are safety shared monitoring success stories that were factors and probability of failures. On the flip experienced both internationally and even side overconservative designs eat into profits locally, a very good example which was closer and fine margins between stability and optimal to home was given i.e. when the Zimplats designs has to be established. He highlighted Bimha mine collapse in 2014 but fortunately that the mining industry has a reputation of early failure signs were picked from closure being unsafe and that the zero harm agenda or monitoring and there was absolutely no drive is perceived as an idealist or unrealistic. casualties recorded. The design process is not complete until monitoring has validated the design. In conclusion Mr Musembwa recommended He went on to show what history has taught us the need for robust monitoring programmes or and how things can really go wrong for example systems, advanced rock engineering profiency, the CoalBrook disaster of1960, Ran mine more geotechnical testing infrastructure and disaster and Ngwarati highwall collapse which better policies & legal framework. ■TMMM then creates the question of preparedness. Mr Musembwa noted the industry is not there yet in terms of preparedness. He went on to prove it by highlighting the lack of rock engineering knowledge and research which creates information gap in the industry, secondly lack of an understanding variability and behavior of rock properties and rockmass in situ tests and lastly but not least very few or non at all monitoring programmes which are important in giving early warning signs. Next he talked about the US$12 Billion industry which would require expansion into previously inaccessible reserves, optimised extraction rates & ratios and also mining at depth and that means this would require support. There would be need to embark on extensive exploration programmes, rock and rockmass testing, labour upskilling in terms of proficiency, policy & legal frame work and Page 52 | the mine manager volume 2
