Rare earth mine in-situ mine dipping auxiliary leakage device and application method thereof

Abstract

The invention belongs to the technical field of rare earth mine exploitation auxiliary equipment, and in particular, relates to a rare earth mine in-situ mine dipping auxiliary leakage device and an application method thereof. The device comprises a liquid inlet hopper, and a liquid inlet pipe connected with the liquid inlet hopper, wherein the diameter of the liquid inlet pipe is 15-35 mm; the length of the liquid inlet pipe is 1350-1400 mm; small holes are formed in the liquid inlet pipe; the number of the small holes is 3-15; and the diameters of the small holes are 5 mm. The rare earth mine in-situ mine dipping auxiliary leakage device and the application method thereof, provided by the invention, are not limited by the production scale, simple and applicable in structure, easy to operate, low in cost, environment-friendly in production and free of pollution, guarantee no collapse of a liquid injection shallow well, and reduce the slippage probability of a humus layer, a clay layer and a weathering mine layer on the earth surface.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for mining rare earth mines, and in particular relates to an auxiliary seepage device for in-situ leaching of rare earth mines and a method for using the same. Background technique [0002] Ion-adsorbed rare earth ore is a unique rare earth resource in southern my country and rare in the world. The medium and heavy rare earth elements it contains have a very important impact on the development of new materials and new energy technologies in the world. [0003] The traditional mining methods are mainly barrel leaching, pool leaching, in-situ leaching and other methods to achieve. The operation process of the sodium chloride barrel leaching process is as follows: the ore mined after stripping the topsoil is transported to the room, and after screening, it is placed in a wooden barrel, and the sodium chloride solution is used as the leaching agent to leach the rare earth, and the obtained...

Problems solved by technology

However, there is still a water head difference between the high-allocation tank and the liquid injection shallow well, which leads to the phenomenon that the upper soil layer of the liquid injection shallow well is easy to seep, and the leachate has a large seepage force on the well wall, and the liquid injection shallow well wall soil layer is basically. Seepage deformation occurs, which leads to the subsidence of the liquid injection shallow well, which increases the possibility of soil slope slippage in the in-situ leaching of rare earth mines
