It can be seen from Figure that under different temperature conditions (10, 20, 30, 40 °C), the cumulative gas desorption amount of coal samples increases with time extension, showing an overall trend of rapid rise in the early stage and gradual slowing down of the growth rate in the later stage until it stabilizes.
