The Erdaogou Mine are mainly composed of steeply inclined extremely thin veins.The mining depth has reached 1 500 m and with more intense ground pressure activities in the process,the influence on mining movement gets severe.According to the theory of rock mass mechanics,the law of surface movement under the influence of high stress environment in deep mining is studied through the application of Midas-GTS software and numerical analysis.Based on the geological and rock conditions of Erdaogou Mining District,the level mined by short-hole shrinkage method continues to subside,and when it reaches the 420 m level,the maximum subsidence is around 7 mm.When it goes further down,the subsidence degree is steady.Deep mining has little effect on surface movement,with the maximum subsidence of the surface less than 8 mm and not reaching the boundary of the traditional boundary angle.
