In this paper, the structure of the coal mine pneumatic-driven gunite system was shown, the working principle of pneumatic hydraulic system was analyzed; the dynamic characteristic of the gunite material in the screw propeller was also analyzed in detail. The study to the pressure, flow rate and torque or power is very helpful to the designing of the machine. The conclusion can be obtained that benefit of this gunite system applied in coal mine is practicable.
