Abstract：AC motor frequency control of motor speed technology is a rapidly developed electric driving advance technology in recent decades and the application fields are very wide. As a freezing station of a high energy consumption construction site ,an utilization of the electric power in each item cost of the whole ground freezing project would take a max percentage and would be a key point of energy sav-ing. The paper stated the necessity of the frequency conversion technology applied to the ground freez-ing project and the important significances to the energy saving and increased efficiency and briefly in-troduced the application condition of the frequency conversion technology to the freezing station of the mine ventilation shaft in Yangcun Mine and the economic benefits obtained.
