| Abstract: | In the light of the characteristics of frozen soil, the processes of cutting and percussion are theoretically analyzed. In addition, the exhaust problem of the drilling tool is discussed. Practice reveals that, the boring speed is enhanced when the different equipment is adapted to the different frozen soil. |
