发布时间：2019-05-12 10:40
【摘要】：为了精确预测煤矿构造、采空区及含水体等地质异常体,采用矿井瞬变电磁法在晋城矿区井下进行了大量试验研究,通过收集构造、采空区等典型地质异常体验证案例,分析电磁场响应多参数曲线,识别不同地质异常体的电磁场响应特性,形成各类便于分辨的可视化图件,来解释矿井构造、采空区及含水体等地质异常体分布范围及特性,达到精细化探测目的。结果表明:整体电位值相对较低,视电阻率值相对较高,且电位和视电阻率曲线出现跳跃起伏,这是识别不含水构造或采空区的典型电性特征;整体电位值相对较高,视电阻率值相对较低,电位和视电阻率曲线较为圆滑衰减,反演深度较正常岩层深度要浅,则是含水构造或采空区积水的典型电性特征。
[Abstract]:In order to accurately predict the geological anomaly bodies such as coal mine structure, goaf and water bearing body, a large number of experimental studies have been carried out in Jincheng mining area by using mine transient electromagnetic method, and the typical geological anomalies such as structure and goaf have been collected to verify the cases. The multi-parameter curve of electromagnetic field response is analyzed, the electromagnetic field response characteristics of different geological anomaly bodies are identified, and all kinds of visual maps are formed to explain the distribution range and characteristics of geological anomaly bodies such as mine structure, goaf and water-bearing body. To achieve the purpose of fine detection. The results show that the whole potential value is relatively low, the apparent resistance value is relatively high, and the potential and apparent resistance curve appear jump fluctuation, which is a typical electrical feature to identify the water-free structure or goaf. The overall potential value is relatively high, the apparent resistance value is relatively low, the potential and apparent resistance curve is smooth and attenuated, and the inversion depth is shallow than the normal rock depth, which is the typical electrical characteristic of water-bearing structure or goaf.
