Abstract: For the pump station of Shiping roadway in Henan Dengcao mine, as the complexity of surrounding rock stress conditions, high embedded depth and other factors resulted in the support difficulty increasing.In this paper, aiming at the destruction of this chamber, we used the numerical simulation software ABAQUS and analyzed the failure mechanism of this chamber, then we got the stress and displacement effects which the construction of pump house near the water storage chamber caused to the pump house chamber, thus we reinforced the rock mass between the pumping stations and water storage by using the “three anchor” support means in order to achieve the stability control of pump house chamber.Monitoring results show that the supporting program has played a good supporting role.

Key words: Deep mine, Multi-chamber, Stability control
