Abstract: Soft rock roadway is prone to plastic deformation and shear failure, floor heave, roof subsidence and two side convergence, which is unable to meet the normal use. In order to improve the mine roadway support intensity, bolting and grouting reinforced support technology is adopted to reinforce roadway. By using the numerical simulation software analysis and combining with the actual measurement, it gets that more than 80 m away from the work surface, the converge of roof and floor is 100 mm and the converge of two ribs is 120 mm. After the field experiment, the result proves that bolting and grouting reinforced support technology not only improves the integrated loading capacity of support structure, but also enhances the soft rock roadway intensity.
