Size adjustable end portion ore drawing similarity simulated test box and application method thereof

Abstract

The invention discloses a size adjustable end portion ore drawing similarity simulated test box and an application method thereof. The test box comprises a vertical rod, a long cross bar is arranged in the surface of the vertical rod, short cross bars are arranged in left and right sides of the long cross bar respectively, surfaces of the vertical rod and long cross bars are provided with threadedholes, bottom cross struts are arranged on left and right of the top center of the long cross bar respectively, a base plate is arranged in the tops of the bottom cross struts, the front and back sides of the vertical rods are provided with right-side backboards respectively, and left and right sides of the vertical rod are provided with lateral backboards respectively. Due to cooperation among the vertical rod, the long cross bars, the short cross bars, the bottom cross struts, the base plate, the right-side backboards and the lateral backboards, the size of the end portion of the test box can be adjusted conveniently, ore drawing similarity simulated test requirements under different similarity test conditions can be adapted to, the working efficiency is improved, and the problem that the size of a present text box cannot be adjusted is solved.

Description

technical field [0001] The invention relates to the technical field of mining engineering, in particular to a size-adjustable ore-drawing similar simulation test box at the end. Background technique [0002] Due to the complexity and non-reproducibility of underground mining projects, it is impossible to conduct too many mining tests on the project site. At the same time, there are still problems such as high cost and long cycle in the field industrial tests. It is an effective method for related technical problems in the mining process. On the premise of following the similarity principle, a similar model that can simulate caving ore drawing is made and a simulation test is carried out on it, which can effectively avoid the problems of high cost and long cycle of field tests. Good economic effect. At present, there are many similar simulation tests for caving mining and drawing in one direction along the ore body trend or inclination. There are few similar simulation tests...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a similar simulation test box for ore drawing at the end with adjustable size, which has the advantage of adjustable size and solves the problem that the density of the existing test box cannot be adjusted.
