摘　　要：邢台矿25305、25307工作面采用沿空留巷方式布置,在施工瞬变电磁时采用在沿空留巷向两工作面施工探测角度的布置方式。这种布置方式在邢台矿的探测取得了较好的成果,解析每个探测角度的图件,经验收和矿方钻探验证后未圈定明显低阻范围,对矿方的地质工作和瞬变电磁施工具有指导意义。The No.25305 and 25307 faces in Xingtai Mine were the working faces arranged by gob-side entry retaining,and the detection angle was arranged from gob-side entry retaining to the 2 working faces in the construction of transient electromagnetic.This arrangement had achieved good results in the detection of Xingtai Mine.The maps of each detection angle were analyzed,and the obvious low resistance range was not delineated after check and drilling verification.It had guiding significance for the geological work and transient electromagnetic construction of the mine.
