The maximum depth for ice core drilling in dry holes is limited due to bore hole closure by the action of the hydrostatic pressure and the difficulty to obtain unbroken cores below a certain depth. In this paper we discuss the various sources of stress that act on the core and the consequences for the design of mechanical ice core drills. We present the latest version of our mechanical drill system which has been modified to produce better cores from greater depths.
