Ice core hot-flid drilling

Abstract

Fast hole production is possible using ice core hot-fluid drilling. The present paper describes a method for calculation of drill penetration rate dependent on the fluid flux, fluid temperature, physical properties of fluid, size of hot-fluid drill head and properties of ice. The design and description of an experimental model of an ice core hot-fluid drill and the experimental data obtained are given. Calculated and measured rates of the drill penetration are compared.
