Test and research on relationship between seam gas features and vibration wave parameters

LIU Sheng-dong~(1,2),ZHAO Qiu-fang~1,ZHANG Ping-song~1,GUO Li-quan~1(1.School of Resources and Environment Engineering,Anhui University of Technology,Huainan 232001,China;2.Mine Geology Committee,China Coal Society,Huainan 232001,China)  
The paper analyzed the seam spectrum features,wave velocity and attenuation features in Mine of Huainan Mining Area.The test results showed that there was good relativity between the seam gas content and the dynamic parameters of the vibration wave in the seam of the mine.There was a linear related relationship between the seam gas content and the vibration wave velocity.With the seam gas content increased,the wave velocity in the seam would be steadily reduced.There was a good linear relativity between the seam gas content and the seam existed main frequency value.The seam gas content was logarithmic related to the seam vibration wave attenuation parameter.The gas content was linearly related to the quality divisor.
