Abstract: The invention provides an induced polarization method and system mounted on a while drilling-type drill rig based on a long-length power source for water detection in tunnels, wherein the IP system comprises a long-length power source module for power supply while drilling, comprising a long-length power source and an electrode being a drill pipe of the while drilling-type drill rig; an array-type data collection module; and, a positioning and interpretation module, that may interpret and image data induced separately when a point power source is located near a drill bit at a current time obtained by differentiating an IP signal for water detection in tunnel at the current time from an IP signal for water detection in the tunnel at a previous time, to realize a dynamic identification of hazardous water sources in front of the tunnel face, and the detection while drilling or multi-detection while drilling.
