Designed and manufactured to withstand the harshest conditions possible. The Shova rock drill systems are new semi-mechanised rock drill technologies suitable for applications across all hard rock mining environments.
The Shova rock drill systems are new semi-mechanised rock drill technologies suitable for applications across all hard rock mining environments, such as ultra-low stoping widths, as well as gully and development end applications.
Traditional hand-held conventional hard rock drilling is without question a tough, dangerous and physically demanding job. It requires great skill, physical strength and endurance, and courage. The number of individuals with this unique combination has dwindled, as has the number of people willing to put themselves into that space and genuinely apply themselves to the job. As a result, mines have experienced dramatic decreases in drilling efficiency and hence profit margins. Simultaneously, they have had to having to deal with a much more onerous regulatory environment regarding safety and increasingly fractious employment relationships with their rock drill operators (RDO).
For a number of reasons, mechanisation is not the panacea that some hold it out to be. The highly specialised and technical equipment required to mechanise a hard-rock mining environment comes with a huge Capex price tag, which is unaffordable for mines in the current economic climate. South Africa also does not have the human capital skills base needed to operate and maintain this highly specialised equipment. Mechanisation, therefore, requires the importation of skills. These skills are very expensive, and their limited availability can mean protracted downtime while they are sourced.
In addition to the human resources and capitalisation cost implications, the South African mining environment is not ideally suited to full mechanisation as most of the country’s platinum and gold is found in narrow seams. While there are on-going developments in mechanised and remote-controlled equipment for use in ultra-low stoping heights, these are even more costly. Increasing the stoping heights to accommodate mechanised equipment results in lower yields and higher effective running costs, as too much waste rock is drilled, blasted and processed.
Semi-mechanisation of drilling through the implementation of the Shova drilling systems is the ideal way to bridge the divide between the conventional methods, which are no longer working or sustainable, and mechanisation. Shova takes the skill and strength that would normally be required of the RDO and engineers it into the drill rig, using simple but innovative mechanical techniques. There are no electronic or electrics, nor is there anything required to operate the rig that a RDO would not already know and understand very quickly. Shova makes a small change to how drilling is done, with a massive positive impact in terms of efficiencies and safety, and hence mine profitability and sustainability.
