1 BACKGROUND The cryosphere covers a relevant portion of the Earth’s surface,playing a major role for terrestrial and marine biomes(Bosson et al.,2023;Sands et al.,2023;Anesio et al.,2017).Glacierets,glaciers and ice sheets represent together 10%of the global land surface,while the annual average maximum of snow cover during the winter accounts for up to 49%of the Northern Hemisphere’s surface (Qin,2017).Aerosols are another major component of the Earth system,playing pivotal roles in the biogeochemical cycles and in the Earth radiative mass balance (Bellouin et al.,2020;Carslaw et al.,2010).A complex network of interactions links aerosols and glaciers.

Seismic evaluation of the destress blasting efficiency

引用

Journal of Rock Mechanics and Geotechnical Engineering 2022年第5期14卷 1501-1513页

作者： krzysztof Fuławka Piotr Mertuszka Witold Pytel Marcin Szumny Tristan Jones Research and Development Centre KGHM Cuprum Ltd.Wrocław53-659Poland Luossavaara-Kiirunavaara AB(LKAB) MalmbergetSE-98381Sweden

In this paper, selected methods of destress blasting efficiency assessment are presented, and novel quantitative methods based on in situ seismic measurements are proposed. The newly formulated solution combines two different approaches. The first, which is useful mostly for the near-field seismic analyses, is based on the analysis of seismic amplitude characteristics, and the second, relevant for farfield evaluation, is extended by the duration and frequency of the seismic wave. Both approaches are based on the seismic analyses of the waveforms generated by blasting recorded by the local seismic network. The proposed solutions are tested and validated in deep underground mines in Poland in which the room-and-pillar mining method is applied. Based on performed analysis, it is shown that both methods may be used as a rockburst hazard control in underground mines. However, developed methods may also be successfully implemented in other engineering practices, including the assessment of seismic vibrations in open pits and quarries.
