Abstract: Taking the main haulage roadway of Yili No.1 mine as engineering background, the roadway floor heave deformation characteristics and produce mechanism were summarized and analyzed with laboratory experiment. Based on this, a joint control scheme of bolt-grouting support and reinforced concrete floor that combined active support with passive support is presented, and the distribution laws of displacement, stress fields and plastic zones of roadway surrounding rock using this joint control scheme or not were analyzed by numerical simulation. The results show that the joint control scheme can not only control floor heave effectively, but also decrease the roof subsidence deformation and roadway walls convergence, and reduce the surrounding rock mass plastic zone extension. The field monitoring data are consistent with the simulation results, which proves that this scheme can get good control effect.
