Problems solved by technology

However, due to the scarcity of gold mines mined by the non-pillar segmental caving method, and the non-magnetic nature of gold mines, it is impossible to carry out ore drawing tests. At present, there is no relevant research on the optimization of stope structure parameters for gold mines using this method

Embodiment Construction

[0025] 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.

[0026] In the embodiment of the present invention: provide a kind of ore-drawing test and optimize the method for stope structure parameter of gold ore caving method, comprise the following steps:

[0027] Step 1: At present, the ore-drawing test is mainly carried out in iron mines. Because iron ore is magnetic, ore and surrounding rock samples are directly taken from the underground of the iron mine, and transported to the laboratory according to the similarit...

Abstract

The invention discloses a method for optimizing structural parameters of a gold ore caving method stope through an ore drawing test. The method comprises the four steps of determining ore drawing test ore and overlying strata materials, determining the shape of an ellipsoid through a single test, determining the section height and the drift distance through ellipsoid three-dimensional arrangement, and optimizing the drift size and caving step pitch through a three-dimensional test. By means of the method, the problem of optimal selection of the stope structure parameters of the gold mine sill-pillar-free sublevel caving method is solved, when gold ore is adopted for ore drawing tests, iron ore is adopted as covering rock. Meanwhile, in order to guarantee the test accuracy, existing magnetite in a laboratory is used for a comparison reference test; according to the method, theories and tests are combined, the optimal segment height and the route distance are determined, then the three-dimensional test is carried out according to different parameter combinations, pertinence is high, the process is clear, and blindness caused by determination depending on human experience in the past is avoided; in addition, the three-dimensional model can be made of a transparent glass material, and the ore rock release form can be visualized in the whole process.

Description

technical field [0001] The invention relates to the technical field of metallurgical mines, in particular to a method for optimizing gold ore caving method stope structure parameters in ore drawing tests. Background technique [0002] Since the segmental caving method without pillars was first introduced into my country in the 1960s and 1970s, it has been widely used in metallurgical mines in my country. Because of its large production capacity and simple method, it has been successfully applied in many large-scale metallurgical mines and achieved significant economic benefits. At present There are still many large iron mine designs using this method. The stope structural parameters of the non-pillar segmental caving method play a decisive role in production capacity and recovery economic indicators. With the development of advanced rock drilling equipment and shovel loading and transportation equipment, the stope structural parameters are also increasing. The maximum sectio...
