Improving the precision of blast-induced seismic effect measurement results

Abstract. Blasting is a commonly used technique in mining, construction, and geotechnical projects for breaking rock. While it is cost-effective, it can also have several negative impacts on the surrounding environment. These impacts include fly-rock, air blast, and blast-induced seismic effect, with the latter being the most significant. The seismic effect of blasting can cause ground vibrations that may lead to damage to nearby structures or affect the stability of the ground. However, not all measurement records are appropriate for calculations related to the seismic effect of blasting. A series of research and test blasts were carried out to assess the advantages of utilizing a larger number of instruments in a single measurement line. The focus was on determining the optimal positioning of these instruments and developing effective strategies for handling any outliers that might arise during the process. The results of these tests will enable us to refine our data collection methods and improve the accuracy of our measurements going forward.
