In order to realize safe mining,based on the theory of geophysical methods for mine dynamic disaster monitoring, with inspection of Wanfeng Mine mining footage, gas emission and tested geophysical signal, the coupling relationship between the parameters determined the reasonable driving speed. The results showed that roadway stress mining speed is 2 m / shift, the safe driving method is 1.6 m / shift, 2.4 m / shift, 2.4 m / shift in cycle or at a speed of 2 m / shift. Rock blasting amount was about 35 kg, the daily footage at about 2 m, the stress concentration causes little failure degree to rock body, with safe mining.
