Environmental Friendly Technology in Breaking Hard Rock
Hard rock excavation is most often achieved either using heavy duty rock breaking equipment or by adopting drill and blast methods using commercial explosives. But both methods are considered not environmental friendly in which the first method creates continuous noises and dust causing nuisance to public; and the second method may have social and environmental concerns on possible fly rocks, high vibration, high air over pressure and air pollution.
Plasma Rock Fragmentation Technology is commonly used in overseas rock breaking projects such as South Korea and getting to be noticed and applied in Hong Kong in recent years.
It is important to understand how it works and how it can be used to minimise the adverse environmental impacts associated with conventional methods of rock breakage, by reducing the dust, vibration and noise. More importantly, it can be demonstrated to be a safe and reliable rock breaking solution for hard rock excavation operations in urban area.
We are excited about the prospects for the use of this technology where ever-tightening controls on noises, vibration, environment, storage and transportation regulations are making conventional blasting methods more difficult to adopt.
This talk will present satisfactory and controllable rock breaking monitoring data at different sites in Hong Kong. Plasma Rock Fragmentation Technology is a great tool to help the construction industry to improve their productivity with pro-environment, safety and workability effect.
