A liquid collection process with liquid guiding holes for in-situ leaching an ore body to extract rare earth elements, including : 1) multiple liquid collection channels are provided in an ore body; 2) liquid guiding holes are arranged near the bottom and on both sides of the channels, and these holes and the channels jointly constitute a multi-channel mother liquid drainage and collection control network; 3) a blocking wall is provided in the channels, a front lower part of the wall is connected to a channel outlet by a conduit controlled with a ball valve switch at the outlet; 4) a multi-channel mother liquid collection network of liquid collection engineering control system is finally formed through the alternate operation of pressure release and increase. The process reduces the loss rate of mother liquid, reduces environmental pollution, and improves the recovery rate of rare earth elements.
