EH4大地电磁测深系统在山东临淄地区岩溶裂隙水勘查中的应用

Electromagnetic Sounding System in Karst Fissure Water Exploration in Linzi Area of Shandong Province

摘要:

EH4大地电磁测深系统是较为先进的电磁法勘探仪器，因其轻便高效、勘探深度大和反映直观的优点而广泛应用于矿产勘查和工程水文勘查中。山东淄川地区岩溶裂隙水勘查中，通过EH4电磁测深工作并结合实地水文地质调查，在确定了构造带的水源补给及赋水条件的情况下，找到了含水断裂带或裂隙带，根据地质体的电性差异来测定构造带的宽度、延深、产状及赋水性，资料显示异常清晰、显著，且与钻探验证结果位置吻合，取得了较好效果。也为EH4系统在深部水文勘查中的应用指明了方向。

Abstract:

EH 4 magnetolluric sounding system is an advanced prospecting instrument. Due to its advanges of light efficiency, exploration depth and reflect intuitively, it is widely used in mineral exploration and hydrological exploration. During karst fissure water prospecting in Zichuan area of Shandong province, through EH4 electromagnetic sounding work, combining with field hydrogeological investigation, under the condition of determining water supply and water bearing condition of the structural belt, waterbearing fault belts and fissure belts have been found. According to electric difference of geological ore bodies, width, depth, occurrence and water occurrence of structural belts have been determined. It is fit with the locations gained by drilling results. It indicates the direction of deep water exploration by using EH 4 electromagnetic system.
