天然源面波在采空区探测中的应用

Application of Natural Source Surface Waves in Goaf Survey

利用天然源面波信息的微动勘查方法具有简便、快捷、低成本、对观测环境无特殊要求的特点,在实际应用中越来越受到重视。微动勘查方法与其它物探手段相结合,对解决资源勘探领域的采空区构造问题已显现出其潜在的优势及前景。文章以九台市羊草沟煤矿采空区为研究对象,分析了基于空间自相关法的微动勘探技术对采空区探测的可行性。工程实例证明,基于空间自相关法的微动勘探技术可以有效地实现对采空区的探测。

The microtremor exploration method using natural source surface wave information is simple, rapid, has low cost, and has no special req.ulrements for observation environments, more and more attention is taken to it in the practical applieations.The microtremor exploratxon techniques combined with other geophysical methods have shown the potential advantages and prospects in solving panel stlrq.cture proble.ms.In this paper, the research object .is the coal mine goal in Yangcaogou Coal Mine of Jiutai City. This paper analyzes the microtremor survey techniques based on spatial autocorrelation method applied in goaf detection, and through the project example, it has proved that it can effectively realize the goal detection using the microtremor survey techniques based on spatial autocorrelation method.
