They will also describe how conventional engineering approaches to closing this collapsing shaft would not work because of groundwater flowing into the cavern caused by the shaft collapse and how the construction team came up with a new method using custom-made foam blocks. This project brought national attention to the Thaynes shaft and the unique approach to safely close it. Brian has degrees in Geology and Geological Engineering. His career has been with the Utah Division of Oil, Gas and Mining, Getty Mining Company, JBR Environmental Consultants, and Stantec Consulting. All of his 49 years of professional experience has largely involved working with the mining industry in the U.S. West.
