Anomalous Seismic Velocity Drop in Iron and Biotite Rich

2016. 7. 1. They are associated with a mean P-wave velocity of 6.02 km/s (range 5.82-6.22 km/s) conforming to granitic upper crust, but in contrast have a high mean density of 2.91 g/cm 3 (range 2.75-3.08 g/cm 3 ), which characterise mid to lower crust.

High-Resolution Near-Surface Velocity Model for Depth

Within the H2020-funded Smart Exploration project existing legacy seismic data acquired in the Ludvika Mines are analysed in order to delineate the deposits in depth. Here we present a velocity model derived using first-break traveltime tomography, which represent the near-surface materials at high resolution and can be directly used for refraction static calculations or incorporation and for depth imaging algorithm.

The seismic velocity distribution in the vicinity of a mine

2000. 7. 1. Analysis of the refracted arrivals on a seismic reflection profile recorded along the wall of a tunnel at an iron mine near Thabazimbi, South Africa, shows variations in P-wave velocity in dolomite away from the de-stressed zone that vary between 4.4 and 7.2 km/s, though values greater than 5.8 km/s predominate along most of the profile.

Seismic Reflection Surveys in Search for Iron Oxide Copper-Gold

2015. 8. 10. seismic survey with relatively sparse source-receiver geometry was used to detect the presence of a possible intrusive package within 2km depth range. The modelling results demonstrates that seismic reflection method using 10m geophones and 20m shot spacing can be used to image deposit within the depth of 2km. The

Final Report Role of blast design parameters on ground vibration

2007. 8. 30. velocity as per the current DGMS standard is 5 mm/s. In complying with such a low statutory limit, coal mines located close to surface structures are struggling for their survival. Other conditions being similar, non-coal mines are in a better position because frequencies are relatively high for which permissible levels are also high.

Opportunities in India mining sector PwC

2015. 6. 3. Section 1 Mining industry in India • Large listed state owned mining companies, integrated private mining-metal companies, and independent holdings. SOMC dominate: 72% by value produced but differ by sector (92% in coal, 31% in iron ore). • A large part of the industry is fragmented (573 coal, 553 metallic, 1523 non-metallic mines)

Seismic velocities of CaSiO 3 perovskite can explain LLSVPs

2019. 8. 15. Unexpectedly low seismic velocities of CaSiO3 perovskite in deeply subducted oceanic crust can explain the properties of anomalous continent-sized regions in Earth’s lower mantle.
