AutoStem is well suited for narrow-reef mining operations in underground mines, and for rock breaking of all types in sensitive areas because: There are no shockwaves – the cartridge does not compromise hanging wall and footwall conditions, so no overbreak is created. It is extremely safe, meaning handling and storage poses no site-risk. There is no pulverisation of high value commodity – improving yield and fragmentation size consistency in the blasting process. Continuous mining is a reality – you only need a minimal clearing area and no harmful gasses are released. Suitable for coal mining – large masses of coal can be dislocated with almost no loss in the form of fines and/ or dust. Most cost effective secondary breaking solution AutoStem is also an attractive option in quarrying operations, for all secondary breaking requirements, and in low-height benching work. No clearing area is required– there is no downtime when drilling and blasting. There is no flyrock- equipment does not have to be removed and rock breaking can occur in sensitive areas without ground shock.
AutoStem is great for tunnelling as: Tunnelling can be carried out on a continuous basis – without compromising the structural walls of the tunnel. Ventilation and clearing demands are drastically reduced. There is no vibration – which is key in sensitive areas. Minimal risk of fly rock.
AutoStem is very well tailored for civil demolition and mass excavation works: Blasting can occur all day with minimal cover and no flyrock. No shockwave vibration – so no removal of heavy equipment is required. This makes AutoStem perfect for in-city rock breaking applications, especially where low vibration readings (PPV) is a requirement. In addition, Suitable for residential rock breaking where vibration, flyrock and gasses are not at all tolerable by the surrounding community. Various cartridges sizes make various burden and spacing patterns achievable in all types of concrete and rock. Suitable for rock and concrete cutting close to water supply pipes, fuel lines etc. Suitable for delicate rescue work underground or in collapsed concrete structures.
AutoStem cartridges can be used up to 40m underwater for rock and concrete breaking: No shockwaves are caused – so there is no disruption to ports or harbours. Very limited impact on sea life. Sequential blasting is possible – this radically reduces blasting time and construction/ demolition costs.
AutoStem suitable for embedded rock Continuous trenching is achievable. No requirement to remove equipment during blasting cycle.
AutoStem can be used for all general rock breaking applications: Without the onerous demands and limitations of conventional high explosives Without the cost and time consuming nature of conventional mechanical breakers
