Testing the Utilization of a Seismic Network Outside the Main Mining Facility Area for Expanding the Microseismic Monitoring Coverage in a Deep Block Caving

Applied Sciences, 2022
In the case of mining in an inclined intrusion using the block caving method, the highest stress is usually concentrated in the seismogenic and abutment zones, especially in the front of the sloping area.

Experimental study on the evolutionary characteristics of acoustic signals produced by granite under biaxial compression with different intermediate principal stresses

Frontiers in Earth Science, 2023
Biaxial compression is a typical stress state experienced by the surrounding rock near the excavation boundaries under deep underground engineering, frequently resulting in engineering geological disasters (spalling and rockburst).

Velocities of Long Period Surface Waves and Microseisms and Their Use in Structural Studies : Part I. Mantle Love and Mantle Rayleigh Waves and the Structure of the Earth's Upper Mantle. Part II. Microseisms and Their Application to Seismic Exploration [PDF]

, 1963
Part I: Phase velocities of Love waves from five major earthquakes are measured over six great circle paths in the period range of 50 to 400 seconds. For two of the great circle paths the phase velocities of Rayleigh waves are also obtained.
