Peter Kenyon, TunnelTalk Vertical shaft machine (VSM) technology is being used for the first time on a North American tunneling project. Ballard Siphon Project General Contractor James W. Fowler of Oregon has partnered with Herrenknecht to use the German manufacturer's VSM technology to construct a 145ft x 30ft launch shaft on the south shore of Seattle's Lake Washington ship canal.
To develop deep deposits safely, economically, and above all quickly, Herrenknecht engineers worked with mining company Rio Tinto to develop the Shaft Boring Machine (SBM). The highly mechanized machine has been designed for full-bottom shaft sinking to depths of up to 2,000 meters and for diameters of up to 12 meters in stable consolidated rock.
Historically, the methods for removing the muck after shaft sinking have been tedious and manual. Cactus grab systems are slow and require specific rock sizes to work adequately. Other mucker systems are often unreliable, requiring frequent boom repairs that halt production.
