摘　　要：山东章丘地区由于长年累月的开采矿资源,造成了大面积采空区的形成,不仅严重影响了工农业的正常生产,还阻碍了当地经济的快速发展,为了解决这一问题,现针对工区地质及地球物理特征,利用高密度电法相关装置,根据等值现断面图相关参数,完成对粘土矿采空区的异常特征进行全面比较,比较结果表明:通过将高密度电法相关装置与三极装置进行充分结合,不仅可以精确反映出采空区的实际位置以及采空区的大致空间形态,还能实现对采空区的准确探测。总之,通过将高密度电法与可控源音频大地电磁法进行充分结合,极大地提高粘土矿采空区探测结果的准确性和真实性,使得地球物理法科学应用于地质灾害调查和治理领域中,为促进社会的和谐稳定发展打下坚实的基础。Due to years of mining resources in Zhangqiu area,Shandong Province,a large area of mined out area has been formed,which not only seriously affects the normal production of industry and agriculture,but also hinders the rapid development of local economy.In order to solve this problem,according to the geological and geophysical characteristics of the work area,the high-density electrical method is used to complete the construction according to the relevant parameters of the equivalent current section map The results show that:by fully combining the high-density electrical method device with the three pole device,it can not only accurately reflect the actual location of the goaf and the general spatial shape of the goaf,but also realize the accurate detection of the goaf.In a word,through the full combination of high-density electrical method and controlled source audio magnetotelluric method,the accuracy and authenticity of clay mine goaf detection results can be greatly improved,so that geophysical method can be applied to the field of geological disaster investigation and management,and lay a solid foundation for promoting the harmonious and stable development of society.
