Exploration and Mining
The evaluation of the seismic action generated by blasting, aims to establish the connection between the levels of ground vibration with the parameters of the blasting and the characteristics of the geological environment related to the quarry. In order to assess the seismic effects on site of the mining / civil / industrial objectives within the quarry, the criterion of the oscillation speed of the soil particles was chosen, because it was considered to be the only reproducible parameter for the whole frequency range of earthquakes which depends to a lesser extent on rock properties. Blasting works, especially large-scale ones, with significant amounts of explosives, produce a considerable seismic effect that can be felt in areas more or less closed to the site of the works. The sizing of the charges used both on the delay stage and on the hole, is a concern that must be taken into account when designing the applied blasting technology. The oversizing of the loads that are fired, according to the technology proposed by the framework operating plan, can lead to damage to the structure of civil or industrial buildings, infrastructure elements such as power lines, gas or water pipes, roads and railways. Applied research carried out by INSEMEX specialists over time, through research and development contracts, has led to certified technical solutions, based on field measurements, agreed by all parties involved).
