Our Blind Bore Rigs are capable of advancing shafts up to (6.1 m/ 20ft ) in diameter to depths of up to (1000m/ 3280ft). Our primary goal is to design purpose built drilling equipment to overcome a variety of geological conditions in the most efficient and cost effective way.

Global's Blind Bore Technology is both faster and safer than Conventional Shaft Sinking Technology, with far less underground impact than Raise Bore Technology. Our modular designs allow mine planners to consider depth, diameter, and geological conditions with minimal impact to the equipment footprint and design. Our concept of interchangeable, modular components reduces the cost of ownership, while maximizing equipment utilization and efficiency.
