Description
Summary:Based on experience gained in the construction of frozen test wells, an ice drill testing facility was designed and constructed at the laboratories of the Polar Research Center at Jilin University. This facility allows for the testing of all kinds of mechanical and thermal ice drills throughout the year, including electromechanical cable-suspended drills, hot-water drills, rapid air drills, thermal sondes for subglacial lake exploration, and others. By changing the switching sequence of the refrigerators and adding various materials (such as dust, sand, rocks, or sediments) into the water or to the bottom of ice well, different glacial and subglacial conditions can be simulated. Additionally, this testing facility can be used to train drilling personnel prior to field work. The facility has following parameters: (1) an ice well size (inside the steel liner) of ⌀ 1m×12.5m; (2) an ice freezing time of
