description The invention relates to a method for rapidly judging whether a tuyere small sleeve leaks water. The method comprises the steps that the internal working state of the tuyere small sleeve is observed through a tuyere peephole; observing the working condition of the tuyere small sleeve water outlet pipe, and judging whether return water exists in the water outlet pipe, whether the water outlet flow is uniform and whether a surge phenomenon exists; reducing 1/3-2/3 of water inlet flow of cooling water of the tuyere small sleeve, observing at a water outlet of the tuyere small sleeve, and judging whether the phenomenon is aggravated or not after suddenly increasing the water inlet quantity if the phenomenon of coal gas overflow in return water or water spray formed by coal gas in a water outlet zone occurs; if the tuyere small sleeve is slightly damaged, the water spray phenomenon generated by return water gas is not found when the water inflow is reduced, but water stains or bubbles exist on the outer side of th
