Abstract

The invention discloses an intelligent two-way multi-angle overturn model test device and test method. The intelligent two-way multi-angle overturn model test device comprises a model loading counter-force device, a left-right overturn device, a front-back overturn device and a box cut, wherein the model loading counter-force device can achieve 1 / 2 contraction scale or free overall model size assembly, the left-right overturn device can achieve free quantitative overturn within the scope ranging from 0 degree to 60 degrees, the front-back overturn device can achieve free quantitative overturn within the scope ranging from 0 degree to 90 degrees, the whole system can achieve the left-right overturn and the front-back overturn multi-angle combination overturn, the visualized monitoring of the whole process can be achieved by embedding tempered glass into front-back counter-force beams, the manufacturing of a model and the section view after being taken out and reservation of the model after testing are facilitated, and simulation of deformation damage characters and stratum motion laws of stratums with different geological conditions, stratum dip angles and different model sizes is achieved.

Description

technical field

[0001] The invention belongs to the technical field of scientific research of mining engineering and geotechnical engineering, and in particular relates to a physical model test device and test method for rock formations with different stress conditions, different inclination angles and different model sizes. Background technique

[0002] As the country's demand for resources increases day by day, the intensity of resource exploitation continues to increase, and the intensity of exploitation continues to increase. With the gradual reduction of shallow resources, mining continues to develop to the deep. According to the current situation of resource exploitation, the mining depth of my country's coal mines increases at a rate of 8-12m per year. In recent years, a number of coal mines have entered deep mining, especially the mining of steeply inclined coal seams has always been a difficult problem in mining technology, and the geological conditions of deep coa...

Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] like figure 1 Shown: a two-way multi-angle intelligent flipping model test device system includes a model loading reaction device 1, a left and right flipping device 2, a front and rear flipping device 3, and an excavation groove 4;

[0052] All parts are connected by high-strength bolts. The model loading reaction device 1 is the object to be implemented to realize two-way flipping. The left and right turning device 2 is located at the bottom of the model loading reaction device 1 and is the implementer to realize the left and right flipping of the model loading reaction device 1. The front and rear turning devices 3 are located on the left and right sides of the model loading reaction force device 1 and are implementers for realizing the front and rear turning of the model loading reaction force device 1 .

[0053] As shown in Figure 2(a), the...
