To evaluation of fractured tectonics associated with underground nuclear cavity of 5RTK borehole at Karachaganak salt dome

Using of archive material, results of mercury measurements, seismic survey, neutron gamma-logging of the used and control-observation boreholes at Lira object, the morphology evaluation of fractured-permeable zones connected with the underground cavity formed after a peaceful nuclear test conducted in the 5RTK borehole was carried out. Preliminary solid model of fractured zones resulted from explosion in the rock block enclosing the studied underground cavity was made. (author)
