The network parallel electrical method is a direct current method with the "distributed parallel intelligent electrode potential difference signal acquisition method" as the core technological support. Its data acquisition simulates the style of seismic exploration. Different from the traditional electrical method in which every time of power supply can only pick out data of one measuring point, the network parallel electrical method can simultaneously obtain data of quite a few measuring points for every time of power supply, thus being a fully electric field observation. The authors used the two kinds of methods for the comparative study of advanced detection test in the Dawan coal mine and Wuping fluorite mine in Xinluo District of Longyan City, and conducted the actual tunnel drivage verification. The results show that the network parallel electrical method technology is better and more efficient than the traditional method.
