Ionic rare earth ore floor exploration method

Abstract

The disclosure provides an ionic rare earth ore floor exploration method, comprising the steps of S1, determining in situ ore-leaching blocks and a floor exploration range according to the rare earthoccurrence conditions and distribution; S2, using mechanical drilling within the floor exploration range to acquire the core and collect physical property parameters of a fully weathered shell, a semi-weathered shell and a bedrock; S3, setting measuring points within the floor exploration range, and using a ground penetrating radar and an anti-interference high-density electrical method to collectdata information of the fully weathered shell, the semi-weathered shell and the bedrock stratum; S4, processing the data information, displaying a section image, dividing stratum horizons of the measuring points and calculating the thickness of each horizon; S5, performing interpretation and inversion on the section image, and combining physical properties of each stratum and the characteristicsof the section image to evaluate the fracture development, compactness and stratum water content of each stratum; and S6, performing 3D modeling based on data results of interpretation and inversion,and displaying the rare earth ore floor in a clear and intuitive manner.

Description

technical field [0001] The present disclosure relates to the technical field of rare earth exploration, in particular to an ion type rare earth mine floor exploration method. Background technique [0002] Ionic rare earth ores are mainly formed by weathering and leaching of magmatic granites containing rare earth elements under suitable conditions. The rare earth elements mainly exist in the state of cations and are adsorbed on minerals such as kaolin and montmorillonite to form ore bodies. , the ore body is surface-type and occurs in the weathered crust of shallow surface granite. According to the unique ore-forming conditions of ion-type rare earths, after long-term production practice, the in-situ leaching mining process is widely used for ion-type rare earths. In-situ leaching is to lay out shallow holes according to the mesh size without destroying the surface vegetation and without excavating and stripping the topsoil, and use a series of liquid injection holes to inj...

Problems solved by technology

However, in the way of mechanical drilling, the drilling equipment and auxiliary tools are too bulky, requiring a lot of time and resources, which is time-consuming and labor-intensive.

The most important thing is that since the rare earth ore bodies are usually planar and exist in the entire weathering crust, the weathering crust floor and underground hydrological conditions are not the same in different locations, and mechanical drilling can only observe and study the drilling point, and can only obtain a single-hole view , it is impossible to make a comprehensive evaluation of the entire rare earth mine floor and hydrological conditions
