The influence of para-seismic vibrations, induced by blasting works, on structures: a Case Study
AGH University of Science and Technology, Faculty of Mining and Geoengineering, Cracow, Poland
Underground mining operations are often associated with the necessity to use explosives. Several hundreds of kilograms of explosives, subdivided into small charges suitable for a specific mining job, are used each time in a blasting operation. In many cases, mining engineers carry out remote central blasting works, which means that all the charges placed at faces are initiated from one control point (usually, a control room in the mine) at the same time. Such coordinated explosions generate para-seismic movements whose consequences can be felt on land surface, with subsequent effects identified in buildings and structures. This paper discusses briefly selected standards applicable to the harmful para-seismic impacts. The author presents the results of the research conducted with the intention to identify harmful effects of the basting works carried out in the “Kłodawa” Salt Mine.
Key words: underground mining / para-seismic impact
