Abstract

The invention belongs to the technical field of mining ore-drawing in underground mining of metal mines, and in particular relates to an automatic ore-drawing experimental device and an experimental method that can adjust the inclination angle of the end wall of the working face, and an automatic ore-drawing experimental device that can adjust the inclination angle of the end wall of the working face. It is characterized in that it includes a main body ore storage box, an ore drawing base provided at the lower part of the main body ore storage box, a working face inclination adjustment assembly arranged at the lower part of the main body ore storage box, and the ore automatically screened connected with the ore drawing base processing system. The invention can carry out simulation experiments on ore drawing under various working face inclination angles. During the whole experiment process, the automatic ore drawing can be completed, and the released ore can be separated through the ore automatic screening and weighing processing system, and the experimental data can be automatically analyzed and processed by the computer program. The invention can simulate the influence of the variation of the working face inclination angle on the ore drawing loss dilution when the ore is drawn under different working face inclination angles, so as to find the optimal working face inclination angle and fully utilize and recover resources.

Description

Technical field

[0001] The invention belongs to the technical field of mining ore drawing for underground mining of metal mines, and particularly relates to an automatic ore drawing experimental device and an experimental method capable of adjusting the inclination of the end wall of a working face. Background technique

[0002] Since the pillarless sublevel caving mining method was first used in my country in the mid-1960s, it has been rapidly promoted in metal mines due to its simple structure, high degree of mechanization, low cost, good safety performance, and high mining intensity. Especially it is more widely used in iron mines.

[0003] For the above-mentioned mining methods, the ore drawing research mainly includes laboratory physical simulation experiment method, field industrial experiment method and computer numerical simulation analysis method. Laboratory physical simulation experiment method is an important parameter optimization method before industrial testing in min...
