摘　　要：为了研究瞬变电磁法对浅埋深烧变岩地下水的探测效果,以新疆准噶尔盆地某露天矿烧变岩区为研究对象,从数值模拟与现场实测两方面对瞬变电磁法探测效果进行研究。首先针对研究对象赋存条件建立地电模型,从电阻率差异角度论证理论可行性;其次根据理论结果设置采集参数,结合地质条件分析实测结果,分别推断烧变岩及地下水分布范围;最后采用地面钻探对异常区进行揭露。结果表明,瞬变电磁法适应浅埋深烧变岩地电结构,能准确反映烧变岩地下水范围,适合在浅埋深烧变岩区应用。In order to study exploration results that transient electromagnetic method to burnt rock ground water in shallow,it taking burnt rock area of one open pit in Junggar basin in Xinjiang,and exploration results were studied from two sides of numerical simulation and field testing. Firstly,earth electricity model was built under studying object condition,and theory feasibility was verified form electrical resistivity difference,secondly,collecting parameters were set by theoretical analysis results,field testing results were analyzed under geological situation,and burnt rock and ground water distribution range were deduced,respectively,at the last the abnormal area was exposed through drilling. The results showed that transient electromagnetic method fit for burnt rock earth electricity structure in shallow,and then groundwater scope could be reflected precision,and could be applied in burnt rock in shallow.
