摘要
采用浅层地震勘探技术在矿区第四纪松散地层进行地层、构造和地下水勘探。通过以反射波法为主,折射波、面波法为辅的综合地震勘探方法较为准确地对勘探区地层进行了划分,结合钻孔勘探,有效揭露了矿区第四系地层厚度及地层空间展布特征。地震勘探将矿区地层划分为三大套岩性层,分别为第四系全新统地层、上更新统地层和元古界基岩层,与钻孔勘探揭露地层基本一致。钻孔K1处地震法解释第四纪地层厚度为240m,钻孔勘探揭露厚度为241.37m,验证了地震勘探的可靠性。
In this paper, the shallow seismic exploration technology is adopted to detect the stratum, structure and ground water in the Quaternary unconsolidated strata. Taking the integrated seismic detecting methods based on the main method of reflection wave and the other methods like refraction wave and surface wave, the detected stratum areas are accurately divided. Combined with the geological exploration drilling, the thickness of the Quaternary stratum and the features of the stratum distributions are revealed effectively. The result shows that the seismic exploration can divide the ore strata into the three, the Quaternary holocene strata, the Pleistocene strata and the Proterozoic bedrock, which is consistent with the exploration drilling result.
