RESULTS AND THEIR ANALYSIS OF IN-SITE EARTH STRESS MEASUREMENT IN LIANGLONG GOLD MINE

This paper introduces the means,process and results of in site earth stress measurement in Linglong Gold Mine.To increase the reliability and accuracy of results measured,a series of new theory and technique has been adopted during in site measurement and calculation & analysis of results measured.Through the in site measurement at 12 points from 5 mining levels,the 3 D earth stress status has been obtained.Besed on results measured,the paper analyses the regularity of earth stress distribution in the mine and the relationship of the regularity with geological tectonics.The results measured have great importance to the design of deep mining.
