Abstract

In this paper, the three set of 3307 coal roadway in the coal mine of Zhao Zhuang coal mine is the research object. By using the numerical analysis method of FLAC3D, the limit value of the section width of the coal roadway in the three set of the coal mine in the coal mine is determined. Numerical analysis shows that when the roadway width less than 4.8m tunnel is most can maintain roadway surrounding rock stability and control of plastic zone, roadway surrounding rock plastic area is small, small deformation, when the roadway width is greater than 4.8m roadway plastic zone increases suddenly and to the depth development of surrounding rock, the angle of stress sets in, surrounding rock breakage is serious.
