Stratigraphic modeling method for in situ leaching deposits

Abstract

The invention discloses an in-situ leaching ore deposit stratum modeling method. In the in-situ leaching ore deposit stratum modeling method, a stratum and an ore body boundary do not need to be artificially delineated in advance; based on drilling original data and mineral-bearing and water-containing characteristics of the drilling original data, ore deposit stratum reconstruction and automaticupdating are rapidly and accurately achieved, and spatial subdivision is conducted on an in-situ leaching ore deposit by means of the established stratum sequence spatial geometric model, the stratumthree-dimensional attribute model and the in-situ leaching mining engineering model to generate a three-dimensional rasterized full-information model. In a complex geometric space subdivision process,stratum space geometrical characteristics are accurately reflected, and the principle of physical, chemical and mechanical property change conditions is finely reflected; the sizes of the basic unitbodies are determined in a self-adaptive mode, corresponding stratum information is given to all the basic unit bodies, in-situ leaching ore deposit stratum digital modeling is achieved, on this basis, leaching performance evaluation is accurately conducted, ground leaching area production drilling arrangement and well structure design are optimized, and great practical significance is achieved.

Description

technical field [0001] The invention relates to the technical field of in-situ leaching ore deposit formation space analysis and leaching performance evaluation thereof, in particular to an in-situ leaching ore deposit formation modeling method. Background technique [0002] In-situ leaching is a special mining method. Compared with traditional mining methods, it only needs to drill a certain number of boreholes from the surface to the ore seam. Through the process of liquid injection and pumping through the boreholes, the useful elements of the reservoir can be realized. extraction and utilization. It has the advantages of less environmental damage and low cost, and is increasingly valued and popularized in the mining of strategic and rare resources (such as uranium, rare earth, gold, etc.) at home and abroad. [0003] In-situ leaching mining is one of the commonly used leaching mining methods. In-situ leaching mining is to inject leaching solution into the primary ore lay...
