APPARATUS AND METHOD FOR DRIVING A CAVITY IN MINING

摘要

A device for advancing a cavity in underground mining, including a rotary drive, an axial shaft that is rotatable together with the rotary drive about a longitudinal axis, exactly one extraction drum that is rotatable about an drum rotational axis, and a connecting arrangement which is connected to the axial shaft and which supports the extraction drum, the connecting arrangement being configured in such a way that the drum rotational axis and the longitudinal axis lie in a plane, and are oriented at an acute angle with respect to one another in the advancing direction, in all operating positions during the advancement, characterized in that the extraction drum extends over at least an effective radius of the device in the radial direction of the device during advancement of the cavity.
