Problems solved by technology

After the ore body reserves are proven, it will enter the mining stage. During this period, a large amount of money needs to be invested for the stripping of the surface covering layer or the construction of tunnels. In addition to the huge amount of engineering and the long construction period, the manpower invested in the mining process High material costs and high security risks

Embodiment 2

[0047] A method for in-situ leaching mining of bauxite, comprising the steps of:

[0048] (1) Drilling engineering:

[0049]Use secondary wells; the surface well site 1 adopts "inline" well layout, and the drilling rig slides from the first notch to the last notch one by one. In order to meet the anti-collision requirements, the minimum wellhead spacing is set to 5m; method, reverse seven-point method or reverse five-point method, and the well spacing is 50-100m; including 1 liquid injection well 5 and 8 drainage and production wells 3, the liquid injection well 5 is located in the middle position, and the drainage and production well 3 Located in the peripheral position; Among them, the liquid injection well 5 is a vertical well, and the drainage well 3 is a directional well. The directional well trajectory 4 should pay attention to anti-collision and circumvention. The maximum inclination angle does not exceed 35°. , the well inclination angle is less than 10°, which reduce...

Abstract

The invention relates to the technical field of bauxite mining, and particularly relates to a bauxite in-situ leaching mining method. The bauxite in-situ leaching mining method comprises the following steps of (1) drilling engineering, (2) ore bed transformation, (3) leaching operation, and (4) ground operation. According to the bauxite in-situ leaching mining method, the advantages of an in-situ leaching mining technology are utilized, a set of bauxite in-situ leaching mining mode is formed by establishing an injection-production well network, conducting fracturing transformation and cooperating with ground treatment, the bauxite in-situ leaching mining mode is different from a traditional bauxite open-pit excavation and roadway tunneling mining mode, economical and efficient mining of bauxite can be achieved, soil and water can be saved, the mine environment is protected, and the problem that the environment is damaged by bauxite mining is effectively solved.

Description

technical field [0001] The invention relates to the technical field of bauxite mining, in particular to an in-situ leaching mining method for bauxite. Background technique [0002] At present, there are two main types of bauxite mining in the world: open-pit excavation and tunnel excavation, and both of them are aimed at deposits that are exposed to the surface or buried very shallow. After the ore body reserves are proven, it will enter the mining stage. During this period, a large amount of money needs to be invested for the stripping of the surface covering layer or the construction of tunnels. In addition to the huge amount of engineering and the long construction period, the manpower invested in the mining process The cost of material resources is high, and the safety risk is high. In addition, both open-pit mining and cave mining will cause huge environmental damage to the ore body and its surroundings, including the formation of mine pits due to stripping of the surf...
