A vertical NQ borehole 700 m in depth was drilled
from the starting point, which was the former mine fan
workshop at the 440 m below sea level (b.s.l.). After the
hole had been surveyed the diameter was taken out to
96 mm. The borehole was then surveyed with a georadar
probe (EMR). After the results had been processed the
four deviation points were determined according to the
geological requirements and technical possibilities.
From this vertical drilling deviated holes – each with a
down-the-hole motor and a deviation of about 2° over
10 m – were drilled in the predetermined direction at
four different levels, namely at 239 m, 117 m, 72 m and
69 m. A 500 m b.s.l. cored section was then drilled from
a start channel using the wireline drilling technique.
After encountering some initial problems in the vertical
section all four deviated holes were completed to the
full satisfaction of the client.
Thyssen Schachtbau GmbH is looking forward to
further successful collaboration with K+S KALI GmbH
on future projects.
