A device and method for sinking a shaft during a sinking cycle, in which a support unit is moved once and a boring unit is moved at least twice by means of support cylinders and displacement cylinders. Due to such configuration, an efficient sinking operation is obtained.

The invention relates to a device for sinking a vertical borehole, more particularly a shaft. an extraction borehole in a deposit body. or a foundation borehole in the ground. with at least one excavating tool for excavating material from the bottom of the borehole, with an at least one conveyance means arranged in the active region of the at least one excavating tool for conveying away from the borehole material excavated from the bottom, with a machine frame on which at least two bracing elements are arranged for locking the device in the borehole during boring. with at least one means for vertically raising and lowering the boring device in the borehole and with at least one drive for rotating the excavation tool.

A drill head for creating a substantially vertical borehole in the ground, includes a body connected to a rotational drive of a drilling device; drilling tools on the body, for loosening the ground at a working face of the borehole; suctioning elements for leading away the loosened ground, which can be connected to a pump, and the suctioning elements include an opening region on the body and with at least one opening in the region of the drilling tools. The opening region has may have an elongate extent, and is connected to a suction box with an opening for connecting to the pump. The loosened ground can be sucked through the opening into the suction box with the pump. The suction box is tapered in width from the opening toward the connection opening, and that the height of the suction box increases from the opening toward the connection opening.
