Abstract：Identifying karst,fault fracture zone,collapse column,goaf and other bad geological phenomena in coal field has important guiding significance for coal mining and geological disaster prevention,and it is very necessary to select a geophysical exploration method with strong anti-interference ability,high resolution and small environmental damage.On the basis of the research and summary of the previous experience of the detection of adverse geological phenomena,the frequency resonance method is used to analyze,explain and infer the geophysical characteristics and spatial distribution patterns of adverse geological phenomena in coal field geology.The test results are verified by drilling,and the results show that the frequency resonance method can clearly reflect the bad geological phenomena in coal field.The results show that the frequency resonance method of seismic wave has certain reference and guiding significance for the detection of bad geological phenomena in coal field.
