In order to solve stress concentration, drilling method and KBD5 electromagnetic radiation instrument were adopted to predict dynamic phenomena of the working face, advanced working face monitoring stress was predicted by stress metering and stress pillow stress, Zhaogezhuang Mine 3137D1 working face ground pressure forecasting warning critical index was put forward, meanwhile, high drainage and goaf pipe laying were adopted to drainage gas in goaf, which achieved the goal of return air controlling gas, realized safe recovery mining under deep large-inclination angle complex geological condition and provided experience and technical support for other mine under the similar condition.
