Abstract: The stability of surrounding rock of dynamic pressure roadway in coal mine is very important to ensure the safety of mine production.In order to effectively control the instability deformation of roadway under the influence of mining pressure, taking the dynamic pressure roadway of 2201 working face in Detong Coal Mine as the engineering background, through the analysis of the failure phenomenon of dynamic pressure roadway and the evolution law of surrounding rock stress, this paper puts forward the stability control technology of dynamic pressure roadway cooperative pressure relief surrounding rock.This technology based on two-way cumulative presplitting blasting roof cutting pressure relief and constant resistance large deformation anchor cable yield pressure support.The research shows that the periodic superposition of mining dynamic pressure makes the vertical stress concentration of roadway surrounding rock and the distribution of double-peak arch asymmetry.The deformation of roadway is parabolic, and the roadway in the area with the maximum stress concentration and displacement is prone to instability.Therefore, the dynamic pressure transmission path was effectively cut off after the two-way cumulative presplitting blasting was applied to the dynamic pressure roadway, and the peak stress difference of the roadway was reduced by 19.6 %.After that, the constant resistance and large deformation anchor cable yield pressure support was applied to unloading dynamic pressure, and the reduction rate of roadway section was reduced from 60 % to 13 %.The influence of mining dynamic pressure on the stability of roadway was significantly weakened, which proved that the application effect of the stability control technology of surrounding rock with cooperative pressure relief was good, and it could provide useful guidance for similar mines.
