In view of the low particle recovery efficiency in the current solid fluidized hydrate mining process, a double-jet recovery scheme was innovatively proposed, and the recovery flow field and particle recovery rate were studied by combining experimental and numerical simulation methods. The results show that with the increase in the distance between the front-end jetting and the recovery hole and the distance between the back-end jetting and the recovery hole, the flow field effect between the double jets weakens, resulting in the particle deposition phenomenon becoming more obvious. When the distance between the back-end jetting and the recovery hole is 300 mm, the particle recovery increases first and then decreases with the increase in the distance between the front-end jetting and the recovery hole. When the distance between the front-end jetting and the recovery hole is 300 mm, the recovery increases first and then decreases with the increase in the distance between the back-end jetting and the recovery hole. The results of this paper further enrich the mechanism of hydrate mining and help optimize the design of mining tools.
