高密度电法在煤矿采空区探测中的应用研究

Application research of high-density electrical method in coal mine goaf detection

为进一步掌握煤矿采空区的分布规律,本文以徐州经济技术开发区某采空区为例,在基础地质资料分析的基础上,采用高密度电法布设5条测线对采空区进行探测。根据解译结果,研究区内未完全塌陷的斜井区域长度35~70 m,埋深14~17 m,在治理设计前应采用钻探方法予以验证。研究结果可为相似地质条件下的采空区治理提供前期参考。

In order to further understand the distribution pattern of coal mine goaf,taking a goaf in Xuzhou Economic and Technological Development Zone as an example and based on the analysis of basic geological data,five survey lines were set up using high density electrical method to detect the goaf.According to the interpretation results,the length of the inclined shaft area that is not completely collapsed in the research area is 35-70 m and the buried depth is 14-17 m,which should be verified by drilling before treatment design.The research results can provide preliminary reference for goaf treatment under similar geological conditions.
