Relationship Between Pressure Release Blasting and Surrounding Rock Control of Roadway

Taking a coal mine in Xinjiang as engineering background, using FLAC^3D numerical analysis software, we study the relationship between pressure release blasting and surrounding rock control of roadway. According to the results, the pressure release blasting can improve stress concentration degree, and decrease the probability of dynamic disaster in mining space, but, the integrity and intensity of roadway surrounding rock is damaged to some extent, so, the deformation of roadway surrounding rock is bigger than without pressure release blasting, the using of mining roadway is seriously affected, then lengthening the bolt length can effectively decrease the unfavorable influence on roadway control caused by pressure release blasting.
