Abstract

The invention discloses a rock core holder for measuring transverse permeability of a sandstone-type uranium deposit rock core. The rock core holder comprises a barrel body, a barrel body tail cover, a barrel body end cover, a water inlet tube, a water outlet tube, a water inlet valve joint, a gas outlet valve joint and a water outlet valve joint, wherein water inlet tube installation holes are respectively arranged in the barrel body tail cover and the barrel body end cover; and a water outlet tube installation hole is arranged in the barrel body end cover. A notch for clamping the rock core is arranged on the water inlet tube; one end of the water outlet tube is sealed; and the notch for clamping the rock core is arranged on the water outlet tube. The barrel body tail cover is fixed on one end of the barrel body by a bolt; the barrel body end cover is fixed on the other end of the barrel body by the bolt; the water inlet tube penetrates through the water inlet tube installation holes in the barrel body tail cover and the barrel body end cover, and then is arranged on the barrel body tail cover and the barrel body end cover; one end of the water outlet tube penetrates through the water outlet tube installation hole in the barrel body end cover and is arranged on the barrel body end cover; a water inlet joint is arranged on one end of the water inlet tube; a gas outlet joint is arranged on the other end of the water inlet tube, and a water outlet joint is arranged on one end of the water outlet tube.

Description

technical field [0001] The invention relates to an experimental device for measuring the permeability of a sandstone uranium ore core, in particular to a core holder for measuring the lateral permeability of a sandstone uranium ore core. Background technique [0002] The in-situ leaching mining and exploration of sandstone-type uranium deposits has become an important development direction of the world's major uranium-producing countries. Due to the objective geological characteristics of low-permeability sandstone-type uranium deposits (mainly low permeability), many problems in the in-situ leaching mining process have been caused. Prominent contradictions lead to higher cost of in-situ leaching mining, longer mining cycle and lower mining recovery rate, which seriously hinders the development and utilization of low-permeability sandstone-type uranium resources in my country. The permeability of ore deposits is the most critical factor affecting the injection rate of leachin...
