The large crosssection construction ventilation is very important in underground watersealed cavern group. As a result, the amount of vertical ventilation shafts is increased. In this paper, 3D numerical simulation method is adopted to analyze the distribution laws of CO and the influence of locations of fans in air chamber on fan efficiency. The results show that: 1) The concentration of CO near working face is less than 24×10-6 after 30 minutes of ventilation after blasting of working face, which can meet related requirements. 2) The fan efficiency of 2 line typed is higher than that of 1 line typed; and the fan efficiency with 2 m span among fan group is the highest.
