Automatic acquisition method for electrical method advanced geological forecast and heading machine

The invention discloses an automatic acquisition method for electrical method advanced geological forecast and a heading machine, relates to the field of shield advanced geological forecast, and is used for automatically judging the integrity and the water-containing characteristic of rock in front of a tunnel face of the heading machine. The automatic acquisition method for the electrical method advanced geological forecast comprises the following steps: setting an automatic acquisition trigger condition of a heading machine; the heading machine comprises an upper computer, an electrical method main control unit and an electrode assembly. The electrical method main control unit calculates whether an automatic acquisition triggering condition is met; if the automatic acquisition triggering condition is met, the electrode assembly acquires an electric signal; and according to the acquired electric signals, the upper computer calculates the geological characteristics in front of the tunnel face of the heading m
