摘　　要：采空区主要是人为挖掘地下矿石而产生的“空洞”,据结构特征和稳定性可分为“充水采空区、急倾斜采空区、长壁式采空区、短壁式采空区”4个类型,采空区会对矿山建设和矿井开采造成生产安全隐患,为快速查明地下采空区的具体位置和连通情况,通常采用高密度电法、瞬变电磁法、微动等方法手段对不同深度范围开展勘查,存在抗干扰能力差、天然源信号弱、分辨率不足等缺点,本文以托里地区阿克巴斯陶金矿采空区勘探为例,运用地震频率谐振技术,采集剖面波阻抗数据进行反演解释。研究结果表明,地震频率谐振技术可快速获得人文干扰区地下几百米地质体微弱的波阻抗变化,对于采空区引起的低密度、低波速异常能精准识别,具地形影响小、施工高效、抗干扰能力强等优点,为矿山地质灾害勘查和治理提供技术指导。The goaf is mainly a“cavity”generated by human excavation of underground ores.According to its structural characteristics and stability,it can be divided into four types:“water filled goaf,steeply inclined goaf,longwall goaf,and shortwall goaf”.The goaf can cause production safety hazards to mine construction and mining.In order to quickly identify the specific location and connectivity of the underground goaf,high-density electrical methods,transient electromagnetic methods,micro motion and other methods are usually used to explore different depth ranges.There are shortcomings such as poor anti-interference ability,weak natural source signals,and insufficient resolution.This article takes the exploration of the goaf in the Akbastao gold mine in the Tori area as an example,and uses seismic frequency resonance technology to collect profile wave impedance data.Perform inversion interpretation.The research results show that seismic frequency resonance technology can quickly obtain the weak impedance changes of geological bodies hundreds of meters underground in human interference areas.It can accurately identify low-density and low wave velocity anomalies caused by goaf,and has the advantages of small terrain impact,efficient construction,and strong anti-interference ability.It provides technical guidance for the exploration and treatment of geological disasters in mines.
