摘要

自主探空仪被用于研究南极冰下环境，但由于加热失效，它们有被冻结在冰中的风险。为了回收意外冻结的探空仪，本文介绍了一种热水救援冰钻系统的概念。设计了一种特殊的热水钻井工具，沿着电缆/探空仪向下钻井，并融化周围的冰。理论估算表明，要在500 m冰深处释放探空仪，电力系统需要提供流量为25 L/min、压力大于4.2 MPa的热水。在中国南极中山站附近的实验室试验和实地试验证明了该概念的合理性。对潜在风险进行了评估，并提出了相应的解决方案。本文提出的热水救援冰钻系统为冰下湖的成功勘探提供了安全保障，也为今后的冰盖勘探提供了更多思路。

Hot-water rescue ice drilling system to recover subglacial lake exploring sonde: General concept

Autonomous sondes are used to study the Antarctic subglacial environment, yet they risk of being frozen in ice due to heating failure. To recover an accidently frozen sonde this paper describes a concept for a hot-water rescue ice drilling system. A special hot-water drill tool was designed to drill downward along the cable/sonde and melt surrounding ice. Theoretical estimation indicated the power system needed to provide hot water at a flow rate of 25 L/min and a pressure of more than 4.2 MPa to release the sonde at ice depth of 500 m. Laboratory testing and field testing near the Chinese Zhongshan Station in Antarctica demonstrated rationality of the concept. Potential risks were estimated and corresponding solutions presented. The hot-water rescue ice drilling system mentioned in the paper provides a safety guarantee for subglacial lake successful exploration, furthermore supports more ideas for future ice sheet exploration.

期刊介绍： Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication. - Space and upper atmosphere physics - Atmospheric science/climatology - Glaciology - Oceanography/sea ice studies - Geology/petrology - Solid earth geophysics/seismology - Marine Earth science - Geomorphology/Cenozoic-Quaternary geology - Meteoritics - Terrestrial biology - Marine biology - Animal ecology - Environment - Polar Engineering - Humanities and social sciences.
