Abstract

The invention provides a novel coal and gas outburst similarity simulation test method based on a geological mechanical model test by referring a coal and gas outburst simulation test device and a geotechnical engineering multifunctional test device on the basis of the similar material simulation test concept and the technical concept of the geological mechanical model test. A large-sized three-dimensional coal and gas outburst simulation test device is designed and mainly comprises a reaction frame (1), a hydraulic load (2), a test box body (3), a roadway excavation device (4), a sealing and gas face inflating device (6) and the like. Gas is introduced into a test model of the test box body by establishing a geological structure coal test model (7), so that the geological mechanical model test and the coal and gas outburst similarity simulation test can be reasonably combined, the coal, rock, gas and complex geological structure are integrated, the coal and gas outburst mechanism under variable conditions of the complex geological structure and the coal seam gas reservoir can be explored, and a novel thought is provided for researching the coal and gas outburst mechanism.

Description

[0001] Technical field:

[0002] The invention relates to a similar simulation test method, in particular to a new test method combining a geomechanics model test and a large-scale three-dimensional coal and gas outburst similar simulation test.

[0003] Background technique:

[0004] my country is one of the countries with the most severe coal and gas outburst disasters in the world.

[0005] The statistics of a large number of outburst sites show that coal is related to the occurrence of gas outbursts and the influence of complex geological structures. In the process of coal mining, when the coal seam is in the area affected by the geological structure belt, the gas geological occurrence conditions are complex and changeable, and the unforeseen factors increase, and coal and gas outburst are more likely to occur under the induced conditions of tunneling, coal mining and other operating methods.

[0006] Only by fully understanding the destruction process of the physical equi...
