Automatic ore drawing experimental device capable of adjusting end wall inclination of working face

Abstract

The invention belongs to the technical field of ore drawing in underground mining of metal mines and particularly relates to an automatic ore drawing experimental device capable of adjusting the end wall inclination of a working face. The automatic ore drawing experimental device is characterized by comprising a main ore storage tank, an ore drawing base arranged at the bottom of the main ore storage tank, a working face inclination adjusting module on the lower portion of the main ore storage tank, and an ore automatic screening process system connected with the ore drawing base. The automatic ore drawing experimental device can simulate the influence of working face inclination change on ore drawing loss and dilution during ore drawing of working faces at different inclinations to find out the optimal working face inclination and to fully utilize and recover resources. The automatic ore drawing experimental device capable of adjusting the end wall inclination of the working face is simple in structure, rapid and flexible in assembly, convenient to operate and use in experiments and high in automation degree.

Description

technical field [0001] 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 capable of adjusting the inclination angle of the end wall of a working face. Background technique [0002] Since the pillarless segmented caving mining method began to be 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] The ore-drawing research of the above-mentioned mining methods mainly includes laboratory physical simulation experiment methods, field industrial experiment methods, and computer numerical simulation analysis methods. The laboratory physical simulation experiment method is an important parameter optimization method before industrial tests in mining eng...

Problems solved by technology

Every time an experiment is carried out, a set of models corresponding to the parameters needs to be made; when the experimental parameters change, because the original model is no longer suitable, a new model needs to be made. For a long time, the experimental device used to make the ore drawing experiment model The fixed structure has been used, that is, according to the different parameters of the experimental model, the structure and size of the corresponding fixture are made. This kind of fixture is basically an analog figure 1 The ore-drawing experiment in which the inclination angle of the end wall of the mining face shown in a is vertical, but for the experimental simulation of other working face inclination angles, due to the limitation of the fixing device, the experiment cannot be realized

Moreover, the ore drawing and the separation process of ore and waste rock of this fixed device are basically completed manually, which often leads to complicated operation procedures, heavy workload, time-consuming experiments and low work efficiency in simulation experiments.
