摘要
在碎屑岩地区寻找地下水相对难度较大,其主要途径是寻找构造裂隙。瞬变电磁法在多测道剖面上对构造裂隙具有典型响应特征,据此可以在缺水地区寻找地下水水源。在山西平遥和河南杨村矿,应用瞬变电磁勘探,准确地圈定了构造位置,经钻井验证,于井深300m处见破碎带,终孔深度350m,成井后水量为25m3/h。
To carry on water research in clastic rock areas is relatively difficult and it is mainly through search for structural fissures. On multichannel profiles, structural fissures have typical response characteristics when transient electromagnetic method is used, thus can guide water research in water-deficient area effectively. In Pingyao, Shanxi and Yangcun coalmine, Henan by the use of the method, circled structural position out well and truly, after drilling demonstration, found out fracture zone at 300m depth, well completion depth 350m, water yield 25m^3/h.
