【Abstract】 Abstract The paper analyses comprehensively the observation results of the rock displacemeter gauge,rock body’ sound emission meter and optical stress gauge for Tongjiaguan deposit of the North Mine in Xikuangshan. Through the comparative analysis with the inspection results during the occurrence and development of the large-area ground pressure in the South Mine,the paper points out that the 127～193 stope of the third middle section in Tongjiaguan deposit is now in the signs period of the large-area ground pressure and makes the suggestions on the measures that should be taken to control the ground pressure.更多还原
