index for seismic velocity determinations of the Yates triangle on the 4850 -- conducted during the fall of 2011

Data from Exhaust Drift and Vent Drift work in a table form --- this is "goto" page for data   Go To Data

Railroad track data 12-17-2011 (su format) -- data was acquired with three geophones and source to the north.  channel 1 was horizontal with arrow to the west; channel 2 was vertical; channel 3 was horizontal with arrow to the south.  used geophones from geophone bracket used for 175 receiver for 4850 level data. 100 microsecond sample interval; fallin edge trigger sgy data

surveyed points for receiver and source locations on the 4850
