摘要
为查明拟建区域采空区的分布特征,本文应用瞬变电磁法对拟建区域进行探测。结果表明:在拟建区域识别出采空区5处,其视电阻率值约为20~40Ω·m,呈现出明显的低阻异常;识别出断层1条,断层倾向南,且南部的电阻率值明显低于北部值,经过深部钻孔工程验证,在拟建区域内存在采空区,且具有坍塌变形的特征。本文的研究成果为拟建项目进一步确定治理方案提供了基础依据。
In this paper,the transient electromagnetic method was used in order to find out the distribution features of the goaf.The results showed that 5 goaf areas were identified in the planned area,and their apparent resistivity is about 20~40Ω·m,showing obvious low resistivity anomaly.One fault with southward trend was identified,and the resistivity value in the south of the fault was significantly lower than that in the north.After deep drilling engineering verification,there was a goaf in the planned area,which showed features of collapse deformation.The research results of this paper provided a basis for further determining the governance scheme of the planned project.
