Technological method for ion type rare earth ore in-situ leaching and liquid injection

The invention discloses a technological method for ion type rare earth ore in-situ leaching and liquid injection. The method comprises the following steps: S1, punching, wherein a plurality of transverse liquid injection holes are drilled in the side face of an ion type rare earth ore body at intervals, and the transverse liquid injection holes transversely run through the ore body or point to the center of the ore body from the periphery of the ore body; the multiple transverse liquid injection holes are distributed in multiple layers in the height direction of the ore body, and the multiple transverse liquid injection holes located in the same layer are distributed at intervals in the horizontal direction; S2, pipe insertion, wherein hard long-strip-shaped objects are inserted into all the transverse liquid injection holes, and then connecting pipes are inserted into the transverse liquid injection holes along the hard long-strip-shaped objects; S3, liquid injection and ore leaching, wherein an ore leaching
