Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] see Figure 1-11 , in the embodiment of the present invention, a kind of deep gold mine step type ore prospecting method comprises the following steps:

[0046] 1. On the basis of detailed field geological survey and according to the main mineralization geological signs, the favorable metallogenic area between Jiaojia fault and Sanshandao fault is selected as the target area for deep ore prospecting;

[0047] 2. In the selected favorable ore-forming ...

Abstract

The invention discloses a deep gold mine stepwise prospecting method. The method includes the steps of (1) selecting a favorable metallogenic region; (2) arranging geophysical exploration lines in a certain distance in the selected region, and performing high-accuracy geophysical exploration to obtain exploration data of each exploration point; (3) performing geophysical data processing to form a contour map; (4) building a deep gold mine geological-geophysical prospecting model; (5) determining an ore-controlling fault deep dip angle stepwise change position in accordance with a deep gold mine stepwise metallogenic mode and the geological-geophysical prospecting model to delineate the position, shape and size of a deep gold mine.

Description

technical field [0001] The invention relates to the technical field of deep ore prospecting, in particular to a step-type ore prospecting method for deep gold ore. Background technique [0002] With the rapid development of my country's social economy, underground shallow and surface mineral resources have been consumed in large quantities, and deep ore prospecting has become an inevitable choice for resource protection. Due to the large burial depth of deep underground mineral resources, no direct prospecting clues can be observed on the surface, so it is very difficult to find ore. Li Hui et al.'s "Structural Superposition Halo Searching for Blind ore Method and Research Method" ("Geology and Exploration", 2013, Issue 01) mainly uses geochemical methods to find deep ore and blind ore, and other deep metal ore prospecting methods and crisis The method of deep mine prospecting mainly adopts the idea of ​​on-site prospecting and multiple geophysical methods. At present, ...
