KAPRA Workshop on Eco Friendly Pulse Plasma Rock Fragmentation Technology
IndSTT, jointly with Korea Accelerator and Plasma Research Association (KAPRA) invites the delegates of No Dig India Show 2009 for a workshop on Eco Friendly Pulse Plasma Rock Fragmentation Technology (PPRFT) during the Show, on 19th November, 2009.
Pulse Plasma Rock Fragmentation Technology (PPRFT) is the technological application of plasma and particle accelerator science for subsurface rock breaking operations. It is titled 'Electro Power Impactor (EPI) Method'. The core equipment used in this technology is an Electro Power Impactor (EPI) unit that generates a high pulse electric energy. This energy is supplied to the electrolyte cells filled with powders of Aluminum and Copper Oxide. In a millisecond, the electrolyte, attains plasma state and generates high heat and impact wave (pulse). This heat wave gets transmitted to the surrounding rock bed and, in turn, breaks the rock with weak noise and vibration. The cracked rock, thus generated can then be easily excavated using conventional methods. Conventional alternatives to this technique are dynamite blasting or controlled blasting or hydraulic or mechanical rock breaking methods.
This technology can be quite useful for rock crack and fragmentation works in rock excavation or drilling projects located in or near dense urban areas, near heritage structures or bridges, Airports, Ports, excavation near to Oil & gas pipeline / Railway tracks and other environmentally or ecologically sensitive regions. In addition, if the site related restrictions prohibit dynamite blasting or the hydraulic / mechanical breaker takes longer time due to rock hardness or produces unacceptable noise levels, this technology can provide desired solution immediately. It produces the desired rock cracking and fragmentation results in a shorter and faster manner and can help avoiding project delays. Trenchless applications may include rock cracking and fragmentation activities for shaft construction, or drilling through rock mass where the Indian construction industry stakeholders face difficulties. It may also provide an alternative to expensive rock toolings.
The workshop will explain the basics of technology, its applications, and provide comparative analysis of the technology with reference to the conventional rock excavation and breaking techniques. It is expected that the information provided in this workshop will assist the delegates in developing the introductory knowledge in Pulse Plasma Rock Fragmentation Technology and will be quite useful in their related activities.
