SHAFT SINKING 44 E&MJ • APRIL 2019 www.e-mj.com er than expected and causing a juggling act with scheduling. The majority of the machines and equipment, but also many materials, were imported from Germany or Western Europe, adding some lead time to deliveries. By the time the beginning of the sink- ing was celebrated on December 21, 2018, with the prime minister of Belar- us, Herrenknecht (Herrenknecht AG), Mr. Greinacher (Deilmann-Haniel GmbH), and the team had enough experience to manage just about any obstacle that came their way. Local personnel were trained as machine operators, signalists and slingers within a short period of time so they could work with machines and shaft traps. The Russian and Belarusian miners grew ac- customed to the unique conditions pre- sented when sinking with the SBR, and the specific work requirements to handle them. This did not always prove simple or easy to manage, especially due to cultural differences and language barriers. While the team is going to face many more chal- lenges on the road ahead, they remain confident that through a focus on safe, productive work, the project will continue to progress well, and that a well-coordi- nated team will emerge from the learning process. The team said it feels a sense of pride for coming so far, despite sev- eral starting difficulties. The effort taken to fine-tune and smoothly coordinate the complex machine technology with all of its associated peripheral systems cannot be understated. Working through, and in- timately understanding these processes takes time and a dedicated focus. The installation and operation of a new type of shaft formwork system de- serves a special mention. This consists of two components: the formwork and the support ring. The support ring is support- ed by 24 threaded rods with plate nuts to DMax TM is our new series of screen panels featuring ultra-high open area. By reducing bridge width between apertures, DMax features more openings on the screen panel surface, which translates to increased product pass-through. Used in concert with with our versatile PipeTop II™ support frame, DMax has proven to be extremely effective. If product pass-through and screening efficiency are the keys to your production goals, DMax and PipeTop II are an unbeatable open area combination.
