Problems solved by technology

[0004] Although the three-dimensional similar simulation test system in the prior art has deepened the progress of underground excavation engineering research to a certain extent, it has the following deficiencies: 1) The model size is small, and the geometric ratio will be very small when doing simulation tests. In practice, it is found that the geometric ratio of the model test is too small to reflect the impact of excavation; 2) The size of the model is fixed and cannot be adjusted, which will cause sometimes the geometric ratio is too small, and sometimes it will lead to too much waste of space Material; 3) The direction of force is single, and it is diff...

Abstract

The invention discloses a three-direction loading large-scale three-dimensional analog simulation test counterforce system which comprises an underground concrete counterforce pool and a counterforce frame fixed with the counterforce pool. The system is capable of simulating complex distribution of coal seam stress in different top plate moving stages during underground excavation, manufacturing large-inclination-angle ore bed test pieces is more convenient and effective, rock mass can be stored under the conditions of three-dimensional stress in the whole mining process, and underground space excavation under more operating conditions can be researched. In addition, the aboveground height of the whole system is decreased, and the system is lower in manufacturing cost and more stable.

Description

Technical field [0001] The invention relates to a reaction force system of a simulation test, in particular to a similar simulation test reaction system for studying the stress distribution of an ore body rock mass. Background technique [0002] Similar material simulation test is a laboratory research method based on similarity theory and dimensional analysis, which is widely used in water conservancy, mining, geology, railway and other sectors. The biggest feature of the simulation test is that it can artificially control and change the test conditions, so as to determine the law of the influence of single factor or multiple factors on the pressure of the mine. The test effect is clear and intuitive, and the test cycle is short and the effect is quick. It has played a role in the research of mining science. Great effect. Even in today's rapid development of numerical simulation and calculation science of rock mechanics, similar material simulation test is still an irreplaceabl...
