Abstract:

Based on the analysis of distortion of Dongfeng shafts in the Sihe coal mine,this paper comes up with measuring displacement of shaft site by GPS and relative displacement of shafts by baseline.After six periodic measurements,the reasons and laws of shafts distortion are obtained.

Key words: GPS, geological section, grouting technology, baseline
