Abstract: According to problem of tunnel influenced by above stope working face, stress and deformation situation of surrounding rock of tunnel, which was supported by bolt-mesh-anchor spray+U steel under effect of advance (side direction) bearing pressure generated during stoping process of above working face, were studied using numerical simulation method. Site engineering application results shows that the maximal convergence of two sides and roof and floor of tunnel influenced by mining are 138 mm and 105 mm, respectively. This support mode could improve self-supporting ability of surrounding rock and control tunnel deformation.
