Using blasting caps with electronic delay units, and programmable delay times down to 1 ms, it has become possible to employ wave superposition in rock blasting. It has been hypothesized that fragmentation is improved in areas between blastholes where the tensile waves meet, overlap and interact. An improved fragmentation can, in turn, result in reduced costs for both blasting and transportation of the blasted rock, improved environmental aspects, and reductions in energy consumption during crushing and grinding of the blasted rock, as well as improved metal recovery. In this project, the above hypothesis was further studied in conjunction with developing computational tools for simulation of blasting with electronic programmable delay caps.
Itasca is offering a focused training session with instruction by experienced engineering consultants, hands-on modeling exercises, and open discussion with other attendees regarding best practices.
Since 1956, the CONCREEP conference series has remained the key meeting for physicists, mechanicians, and engineers to present and debate research results and discoveries on the time-dependent behavior of concrete.
Mr. Chen has six years of experience in research and application in geotechnical and hydropower engineering. He has a background in in various engineering practices including numerical modeling, foundation pit design, monitoring and rockburst-risk assessment.
