Abstract
One tunnel located in the north east of Ping Ding Shan city be used to put 5 steel pipes for transporting cinder of the power plant in the city. The tunnel region is just the mining coal subsidence area., so the surrounding rock stability of the tunnel is complicated problem because of strata displacement and subsidence because of mining coal. With in-situ measurement the stability of the surrounding rock of the tunnel is analyzed and evaluated, Conclusion is that the surrounding rock displacement and lining cracking is relevant to underground mining coal. The surrounding rock stability will be influenced further but be not wholesale collapsed and the tunnel can be still normal used.
