Abstract

The present invention discloses one kind of rude ore mining method for ion type RE ore, and the rude ore mining method includes static pressure injecting liquid via geotechnical engineering process, establishing impermeable layer in the bottom of ore block, and forming V-shaped draining holes, liquid injecting holes, tunnel, impermeable layer, etc. in the mine mount. The technological scheme includes proving up the RE ore bed thickness, establishing tunnel in the bottom of the rich ore, setting V-shaped draining holes, setting impermeable layer or transverse draining holes below the V-shaped draining holes, setting liquid injecting holes or tunnels for layer by layer injecting and collecting. The present invention can avoid the adsorption of soil to RE ion and water and soil loss caused by mining.

Description

Technical field

[0001] The present invention relates to a mining method of ion-type rare earth ore mining (ion-adsorption type rare earth ore leaching), specifically applying the static pressure grouting method commonly used in geotechnical engineering to inject liquid in the original mountain leaching mining. Build an anti-seepage layer at the bottom of the ore deposit; and adopt layered liquid injection method and layered liquid collection method when injecting liquid in the ore bed. Background technique

[0002] The known ion-adsorption type rare earth ore former mountain leaching method is made up of liquid injection holes, tunnels and drainage holes arranged above the impermeable layer at the foot of the mountain or the soil layer containing groundwater (see figure 1 ). When chemical reagents (now (NH 4 ) 2 SO 4 For example, the same below) After injecting from the liquid injection hole on the top of the mountain, it penetrates into t...
