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...

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.
