Abstract: According to the monitoring data of surrounding rock convergence and deformation，four kinds of nonlinear function are chosen to build the deformation prediction model of coal roadway surrounding rock by nonlinear fitting technique to achieve regression analysis and prediction of monitoring data.Based on Visual basic programming，a prediction system of coal roadway surrounding rock deformation is established in order to reflect the steady state of the coal roadway timely and dynamically.

Key words: Bolting with wire mesh, Safety evaluation system, Deformation prediction, Engineering application
