Problems solved by technology
The biggest disadvantage of artificial water-sealed floor is that the process cycle is too long, the tail liquid collection time is long, the mother liquid concentration is low, the implementation conditions are harsh, the implementation is difficult, and it is especially difficult to make a good control of the stability of the mountain slope. Therefore, In actual mining activities, artificial water-sealed floors are rarely used

Embodiment Construction
[0033] See attached figure 1 , the specific implementation method of the technical solution of the present invention is as follows: according to the ore body grade distribution and hydraulic principle, the height in the ore body is between 0.015%~0.02% at the bottom of the ore body, mainly along the direction or tendency of the mountain body, as far as possible Supplemented by the higher distribution of the passing grades on the plane, the liquid collection roadway 1 is set up with a slope of 1-2°. Auxiliary roadways 8 are set at intervals of 5-10 meters on both sides of the liquid-collecting roadway, and cement slurry seepage prevention measures can be implemented at the bottom of the roadway 1. A plurality of support pillars 7 can be arranged on both sides of the liquid collecting roadway 1 . After the construction of the liquid-collecting roadway 1 is completed, the sealing wall 3 is implemented every 20 to 30 meters and in front of the nearest support column 7, thereby di...

The invention relates to an on-site extraction and liquid collection process with auxiliary tunnels, which is characterized in that (1) a plurality of liquid collection tunnels are arranged in an ore body; (2) auxiliary tunnels are arranged at two sides of each of the liquid collection tunnels, and the auxiliary tunnels and a main tunnel together form a multi-channel mother liquid drainage and collection control surface; (3) a sealing wall is arranged in each liquid collection tunnel, the front lower part of the sealing wall is connected to a tunnel opening through a guide tube, and the guide tube is controlled by a ball valve switch at an outlet; (4) in the processes of detecting operation and production, by alternately releasing and increasing pressure, a multi-channel mother liquid collection system of a liquid collection engineering control surface is formed finally; and (5) by changing the loss ratio of ore liquid and mother liquid, the purpose of improving the recovery ratio of rare earth is achieved finally. The process of the invention can lower the loss ratio of the mother liquid, is favorable for recovering the mother liquid of the rare earth, can reduce the problem of environmental pollution, and can improve the recovery ratio of the rare earth.
Description
technical field [0001] The invention relates to the technical field of mineral deposit mining, in particular to an in-situ leaching, drainage, and liquid collection process, in particular to an in-situ leaching and liquid collection process for full-complex ion-adsorption type rare earth ore deposits. Background technique [0002] There are two main types of existing full-complex ion-adsorption rare earth leaching and liquid collection technologies. [0003] The first liquid collection technology is artificial false bottom interception and liquid collection. This technology adopts engineering technical measures such as liquid collection roadway, interception hole and cement slurry to carry out anti-seepage treatment on the liquid collection project, and sets up an artificial mother liquor collection system, but the mother liquor is collected. There are some obvious deficiencies in the liquid system. First, the anti-seepage technology of the interception hole is not mature en...
