Analog simulation experiment system and method based on 3D printing rapid prototyping technology

Abstract

The invention discloses an analog simulation experiment system and method based on a 3D printing rapid prototyping technology. A blending module is connected with an experiment module through a printing material laying module. A control module is connected with and controls the blending module, the printing material laying module and the experiment module. The control module is used for forming a 3D digital model of an analog simulation experiment. The control module controls the experiment module to be adjusted to a state suitable for printing the 3D digital model, controls the blending ratio of the blending module through electromagnetic valves and controls the printing material laying module to carry out 3D material laying at the experiment module through a direction control mechanism and reversing valves. The analog simulation experiment system and method can be used for laying rock models on complex geological structures, where the models cannot be laid through traditional measures, such as fold, faults and collapse columns, the model size precision is high, and therefore the system and method can be better used for observation and study of complex rock engineering such as the working seam overlaying strata movement rule, the roof caving regularity, and the relation between the roof moving features and forms and stability time after working face mining.

Description

technical field [0001] The present invention relates to an experiment system and its use method, in particular to a similar simulation experiment system and experiment method based on 3D printing rapid prototyping technology. Background technique [0002] In order to better ensure the safe production of underground mines, exploit mineral resources to the maximum extent, and protect the mining environment and ground facilities, it is necessary to study mine pressure and rock formation law, and develop rock formation support technology and control measures. However, for an underground engineering problem with many influencing factors, it is difficult for people to clearly understand all the influencing factors of the problem, and it is difficult to observe and summarize the movement law of the overlying rock in the mining coal seam, the law of roof collapse, and the characteristics and shape of the roof movement after mining. Complex rock mass engineering problems such as the ...

AI Technical Summary

Problems solved by technology

[0005] (1) The similar model specimens laid can only simulate horizontal, inclined rock formations and fault structures. The laid horizontal, inclined rock formations and fault structures are the simplest one-way structures, and the complexity of the structure is far lower than that of the real site structure. , so the simulation similarity is low;

[0006] (2) Traditional similar material simulation experiments are all artificial or semi-manual batching and laying, which requires the cooperation of multiple people, which is not only labor-intensive, but also takes a long time to lay;

[0007] (3) The traditional similar material simulation experiment adopts artificial laying, and the dimensional accuracy of the similar model is low
