Study on Acoustic Emission Characteristic of Coal During the Process of Successive Cycles of Gas Inflation-deflation

SONG Da-zhao,WANG En-yuan,ZHAO En-lai,XU Wen-quan,FENG Zhan-wen(School of Safety Engineering,China University of Mining and Technology,Xuzhou 221008)  
In order to analyze the acoustic emission signals in the process of contract between coal and gas,the cycle experiments of successive gas inflation-deflation for shaped coal and raw coal samples were carried out,and the characteristics of acoustic emission signals during the process were analyzed.The results showed that the AE signals decreased in each successive cycle and the most evident decrease of cumulative AE events and energy existed during the first and the second cycle.In the same cycle,compared to the process of gas inflation,AE events increased remarkably but energy decreased in the process of deflation.The strength of AE signals of raw coal was lower than that of shaped coal.The change law of AE signals reflectes the development of internal fracture of coal.Therefore,it can forecast gas disaster of coal mine.
