摘要
瞬变电磁方法是近几年来广泛用于深部探测岩层富水的有效手段之一,属于电磁类电法。文章提及的K剖面法来源于常规电法勘探中的对称四极装置电测深方法,属于直流类电法,其基本原理是对实测的直流电测深视电阻率值进行微分,该微分值称之为反射系数K。通过K可以求得视真电阻率值ρz,以及其二次微分值KD。K、ρz、KD是K剖面法解释中的3个参数。将该方法应用于河南某煤矿地面瞬变电磁方法数据处理中,在目标层位定位划分等方面取得了较理想的效果。
Transient Electromagnetic Method (TEM) is one of effectual method which belongs to electromagnetism method to detect deep stratum hydrous properties and is well used during these years. This article mentioned K - profile method which belongs DC class elec- trical method came from the symmetric quadrupole device electrical sounding method of common electronic detecting method. The basic principle is that made differential coefficient for measured electrical sounding apparent resistivity values, the differential value is called the reflection coefficient K. It obtained on apparent resistivity valuespz and its quadratic differential KD by K. K,pz ,Ko are three parame- ters in profile method explained. This method is applied for TEM data processing in coal mine of Henan and it achieved desired results in the target horizon positioning division.
