INSTRUMENTS AND METHODS: A NEW VERSION OF A STEAM-OPERATED ICE DRILL

A further development of a Howorka steam-operated ice drill is given. It is mounted on a pack frame for each transportation in rugged terrain. A propane flame is used to vaporize water in a single-pass fire-tube boiler. The steam is delivered to the ice through a double-walled flexible hose and a straight guide tube with an exchangeable nozzle at the end. One hole, 25 mm in diameter and 8 m deep, can be drilled in 15 minutes; such a hole can be drilled with one tank of water and 10 with one tank of propane. Sturdy construction has been used and the drill has been tested and found to work satisfactorily under both temperate and arctic conditions. (Author)
