For demand of positioning of ground personnel of special coal mine besides to underground personal, the paper proposed a design scheme of personnel positioning system of special coal mine which uses dual-frequency. It introduced system structure and basic working principles, and mainly analyzed key technologies of hardware and software function design of the system. The system realizes all-dimensional tracking and positioning of all personnel of the special coal mine by low-frequency localizer, and improves management efficiency and raises safety level of special coal mine.
