Abstract: The testing system about gas desorption characteristics of coal sample under vibration effect is developed, and the design principle, function composition and operation method are introduced in this paper. According to gas the desorption experiments under different vibration frequency, the systems can meet the experimental requirements. It also finds that different vibration frequency can promote gas desorption and desorption velocity.
