Abstract：Based on the strain monitor systerm of a shaft lining, got a lot of strain data before crack, in cracking and af-ter crack. Through the analysis and contrast of the mine shaft lining data on different layers at the same time point and a given point' s history data, gave the figure of strain characters of the shaft lining crack. And pointed that the in-creased velocity of shaft lining strain get faster, and the shaft lining strain suddenlly decrease in the process of crack, the crack process will last about 10 ～ 15 d. The released amount of strain relate to the location and crack level.
