Description

technical field [0001] The disclosure belongs to the technical field of mine mining model tests, and in particular relates to a multi-field coupled mine intelligent mining model test system. Background technique [0002] In recent years, with the gradual depletion of shallow resources, coal mining has continued to develop to the deep. As the excavation depth continues to increase, roadways often face adverse geological conditions such as high ground stress, high osmotic pressure, extremely soft rock, and fault fracture zones, which can easily lead to frequent disasters, roof caving, and large deformations in deep roadways during construction. Concealed and sudden safety accidents, such as bottom slop, water and mud inrush, etc., cause major safety accidents and economic losses. In order to ensure the safe production of coal mines and improve the economic benefits of coal mines, it is necessary to fundamentally understand the deformation and failure mechanism of deep roadway...

AI Technical Summary

Problems solved by technology

[0003] (1) Most of the model test systems at home and abroad use homogeneous materials, and less consideration is given to the influence of simulated inclined rock formations

[0004] (2) Model test systems at home and abroad are mostly manual excavation, and it is difficult to simulate the automatic excavation of roadways of different shapes and sizes and the automatic mining process of the working face

[0005] (3) Most of the domestic and foreign model test systems can only simulate one or two complex geological conditions, and cannot simultaneously simulate mines under the combined effects of high ground stress, high seepage flow field, inclined rock formation, rock burst, coal and gas outburst, etc. mining process
