摘　　要：网络并行电法是以分布式并行智能电极电位差信号采集方法为技术核心支撑的直流电法,其数据采集模拟地震勘探方式进行,与常规电法每次供电只能采得一个测点数据不同,并行电法每次供电可同时获得多个测点数据,是一种全电场观测技术。运用两种方法对龙岩市新罗区大弯煤矿和武平荧石矿进行超前探测试验对比研究,并经实际巷道掘进揭露验证,表明网络并行电法技术较传统电法技术效果更好,效率更高。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.
