Transmitted channel wave detecting technology of geologic anomalo us body in coal mining face

According to the detection of mutiple types of geologic anomalous bodies occured in large coal mining face,the ransmitted chanel wave energy attenuation coeicient CT inmage technoiogy was aplild to detect the fautsinkhnole and thin seam zone three typical geolgic anomalous bodies in several coal mining fcesThe comparison betwee the detecion resulis and thelate collacted verfied information showed that the energy ofthe transmitld chanmel wave in the fault sinkhnole and the thi seam zone would have obicus ttenuation phenomenon.The se ismic chanel wave energ atenuation cecient CT resuits could effctive refect thelocation and scope of several geologic anomalous bodies.The attenuation coeficient of a geologic anomalous body was 0.03~ 0.06 and attenuation cefficients o different type anomalous bodyies would have a certain difference,but would not be obvious.
