地球物理勘查技术在探测煤矿采空区中的应用

摘要

在阐明采空区特征及其地球物理异常场的基础上,重点介绍瞬变电磁法、反射波法、地质雷达法与EH4大地电磁法等4种地面地球物理探测技术,并结合具体的工程应用实例,总结了各种探测技术的应用效果及优缺点,结果表明,这些方法在煤矿采空区探测方面具有分辨率高、经济快速、准确有效等优势,能够为煤矿安全生产提供指导资料.%Based on a description of characteristics of the goaf and other geophysical anomaly fields, this paper emphatically deals with four ground geophysical exploration technologies, i. e. , transient electromagnetic method, reflection wave method, ground penetrating radar method and EH4 magnetotelluric method, and, in combination with practical engineering examples, sums up the application effects as well as advantages and disadvantages of these technologies. Studies show that these methods have such superiorities as high resolution, low cost, rapidness, high accuracy and effectiveness, and can provide guiding data for safe production of the coal mine.
