Blind Drilling

What is Blind Drilling?

 

Blind Drilling refers to drilling a large diameter shaft from the surface. (No underground access is required.) A Blind-Drilled Shaft can be constructed prior to the underground advancement and off the critical path. Personnel are not required to enter the shaft during the drilling process. Frontier-Kemper has completed more than 5,000 ft. of Blind-Drilled Shafts across the US and has the capacity to drill diameters ranging from 6 ft.–20 ft. and depths of more than 2000 ft. with special applications.

 

FK350MT

 

To provide solutions for mechanically excavated, deep, large-diameter, Blind-Drilled Shafts, Frontier-Kemper, Wirth GmbH, and ACI entered a joint cooperation agreement to build a Blind Shaft Drilling System. The result is the FK350MT; one of the largest, safest, and most efficient A-Frame type drilling rigs in North America. As currently configured, the FK350MT is capable of drilling shaft diameters up to 20 ft. and depths of more than 1,500 ft.
