The Development and Application of Lightweight Alpine Ice Coring Mechanical Rig in China

The past changes of climate and environment can be reconstruct through ice core study, which can provide the vital scientific proofs for thoroughly comprehending and predicting current and future changes of climate and environment . The ice core mechanical rig is as one of the essential tools to get ice core samples, which plays an important role in the acquisition of our alpine glacier ice core. This paper mainly introduces the development, application, problems, prospecting for future of our own designed ice core mechanical rigs for alpine glacier. Our own designed BZXJ rig is well performed, which is one of the best same kinds of rigs around the world, it has been drilled 125 ice cores and 8095m total thickness until the end of 2012, which has made important contributions in ice core research for our country .
