Research of Unloading Technology of Defect Method in Dynamic Pressure Roadway

Abstract:

This paper takes typical stoping of deep-mine dynamic pressure working face of Zhaogezhuang mine of Kailuan mining area for the research background, relieving the dynamic pressure of roadway of burst tendency through building defect method in dynamic pressure roadway. Putting forward the theoretical solution of defect method in dynamic pressure roadway based on elastic-plastic theory;Taking numerical simulation method in view of the material inhomogeneity of actual engineering geological, researching the characteristics of stress distribution of roadway surrounding rock after relieving in defect method; Applying the theory to the stoping of deep-mined impact working face, and the implement effect is good on the spot.
