# Digital Processing of Seismic Data from Open-Pit Mining Blasts
## 6 Conclusions  
The principal hypothesis of this research is that the application of mathematical methods and signal processing to seismograms can provide extended data on drilling and blasting operations applicable to the determination of empirical coefficients in characteristic equations within the time period that do not exceed the system computation cycle. That is, the analysis results of the seismograms associated with the blast wave characteristics propagating through the rock enable us to create an algorithm. This programmed algorithm can provide us with prompt and certain recommendations for optimizing the parameters of drilling and blasting. This is especially relevant considering the mineral sector's current transition to the digital economy [40]. The principal target of this research is to see the dependencies between the spectral, wavelet and fractal analyses results and the blast wave characteristics. The research conclusions are as follows. 1. For the dependence between the dominant frequency and amplitude and the distance to the blast center: the dominant frequency dependency is determined by the equation \(\mathrm{y}=1.0262\chi^{0.2622}\), amplitude dependency by \(\mathrm{y}=18.139\chi^{-2.276}\)
2. Of the entire signal, 80% is concentrated on half of the entire frequency range, i.e., the low frequency zone is the most interesting for the analysis. 3. The distance effect could be estimated by certain frequency range analysis. This research has identified that the 12 th range has a close correlation ratio (more than 0.9), as well as 2, 4-8, 11, 12, and 14-16 ranges with a less close one, but also quite a strong dependency (more than 0.7). 4. Entropy and correlation dimension decrease and predictability time increases when the distance to the blast center increases. The research results confirm the stated hypothesis; however, for a more efficient application of the analysis results for optimizing the parameters of blasting and drilling, it is necessary to expand this research by additional experiments.
