Siemag Tecberg,
Germany,
explains
how the company is
serving underground
coal mines around the
world by providing
tailored shaft hoisting
solutions.
I
t is the nature of things that underground coal mines are different to hard rock mines
in many aspects. Whereas hoisting from great depths (3000 m and more) is required
only in some ore mining, the demand for high capacities was mainly driven by the
coal industry. Siemag Tecberg has been involved in its long history, in particular, in the
German coal mining industry, by advancing the design and development of hoisting.
When the German engineer Friedrich Koepe invented the friction hoist principle, it
was the predecessors of Siemag Tecberg that promoted this idea, because of its huge
benefits. The compact design of the machine and the benefit of all loads in the shaft being
balanced as best as possible minimises the torque requirement of the drives and in
particular the peak power demand. Consequently, the Koepe principle became a success
story for a wide range of winding applications and in particular in coal mines of 700 to
1500 m depth. As the hoisting rope is not coiled but just driven by the hoisting drum, the
use of multiple ropes (so far up to 10) easily allows the increase of the service load, which
means payload and hoisting capacities.
