Research on the Application of Seismic Wave Frequency Resonance Technology in the Goaf of Akbastao Gold Mine in Tuoli County,Xinjiang
The goaf is mainly a"cavity"generated by human excavation of underground ores.According to its structur-al 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 electro-magnetic methods,micro motion and other methods are usually used to explore different depth ranges.There are short-comings 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 reso-nance 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 hun-dreds 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-interfer-ence ability.It provides technical guidance for the exploration and treatment of geological disasters in mines.
