Abstract
A shaft drilling machine comprises a drill head carrying drill tools thereon, a device for guiding the drill head in a shaft, a device for advancing the drill head in the shaft, and drive aggregates which are lowered into the shaft together with the drill head and driving the latter. A sluice for providing a rinsing fluid is arranged in a pilot drill. A rinsing conduit and an ascending conduit for extracting from the shaft a drilled material-rinsing fluid mixture generated during the drilling operation are connected to the sluice which is formed as a bucket wheel.
