Abstract
The invention discloses a method for preventing landslides induced by inappropriate liquid injection intensity in in-situ leaching mining. The method comprises the following steps: S1, drilling a liquid injection hole; S2, integrating an upper-layer mold bag (1), a lower-layer mold bag (2) and other parts into a whole; S3, injecting cement slurry from an inlet of a slurry injection pipe I, wherein the cement slurry enters the upper-layer mold bag (1), so that the slurry injection of the upper-layer mold bag (1) is realized; injecting cement slurry from an inlet of a slurry injection pipe II (6), wherein the cement slurry enters the lower-layer mold bag (2), so that the slurry injection of the lower-layer mold bag (2) is realized; S4, enabling a medicament to be inlet into a liquid injection pipe (4) from an inlet end of the liquid injection pipe (4), wherein the medicament enters a region formed by the upper-layer mold bag (1), the liquid injection hole (10) and the lower-layer mold bag (2), so that the injection of the medicament is realized. The method disclosed by the invention has the benefits that the medicament can be prevented from entering a non-ore body layer and a space between the non-ore body layer and an ore body layer, and due to the effect of an anchor rod, a slippage phenomenon generated between a clay layer and the ore body layer, as well as between the ore body layer and a bed rock is effectively avoided.
