Method for promoting hydration, solidification and separation of coal mine mash gas mixture

The invention discloses a method for promoting hydration, solidification and separation of a coal mine mash gas mixture, which relates to a method for promoting separation of mash gas. The method solves the problems that the prior method for hydrating, solidifying and separating the coal mine mash gas mixture has long induction time of generating a hydrate of 59.8 percent CH4, low growing rate ofa hydrate of 40.4 percent CH4, low concentration of the CH4 in the mash gas mixture, and low separation efficiency. The method comprises the following steps: firstly, adding a separation carrier; secondly, adding an accelerating agent into a reaction kettle, and then pumping out air; thirdly, extracting the mash gas from a coal mine and compressing the mash gas into the reaction kettle to performthe hydration and the solidification; and fourthly, making the hydrates after the hydration and the solidification enter into a storage tank to finish the operation. In the method, the induction timeof growing the hydrate of 5
