Description

technical field [0001] The invention relates to a model test mining and excavation device, in particular to an automatic integrated device for mining, rowing, monitoring and protection used in model tests. Background technique [0002] Model tests are widely used in geotechnical, water conservancy, transportation, mining and other fields. On the basis of geological exploration, for key geological sections, according to the similarity principle, masonry or lay similar material models, apply stress and displacement boundary conditions to it, simulate In-situ stress environment, according to the actual project progress and similar proportions, excavate at predetermined locations, simulate actual working conditions, observe deformation, stress, crack development, failure zones, etc. at the same time, and finally evaluate the stability of rock mass engineering. [0003] Whether the stability evaluation is accurate or not depends on many factors, such as the set ratio and actual r...

Problems solved by technology

As far as excavation is concerned, when the similarity ratio is 100, the excavation error of 1mm on the model is equivalent to the 100mm excavation in the prototype. When the similarity ratio is 200, the accumulated error will be larger, and the resulting stress displacement The distribution error will be larger, and the stability evaluation basis will also have a larger deviation

[0004] In traditional model tests, to simulate engineering excavation, screwdrivers (or similar strip tools) are often used for manual excavation. The amount of excavation each time depends on the concentration of the experimenter, and it is difficult to continuously guarantee the accuracy of excavation. It will also cause secondary damage to the excavation surface, which in turn makes the accuracy of the stability evaluation through the model test insufficient

On the other hand, in addition to excavation, mining area support and monitoring are also important links in model tests. At present, manual methods are mostly used, which has defects in consistency, timeliness and accuracy.
