Abstract

The invention discloses a similar test device and a test method for evolution of multi-field precursory information of water inrush from mining faults in deep confined water, and relates to the field of formation temperature and similar simulation tests. Glass plate, model storage cavity, lateral pressure loading system, vertical loading system, water pressure loading system, water temperature regulation system, ground temperature regulation system, signal acquisition and processing system, test model; the water pressure loading system and water temperature regulation system of the test device And the geothermal regulation system can provide stable high temperature, high pressure water and gradient formation temperature for the test model, which can better simulate the real geomechanical environment of the deep confined water-bearing fault-bearing coal measure strata, which is beneficial to the high water inrush of the deep confined water-mining faults. Real reproduction of field precursor information, inversion analysis of the evolution law, coupling characteristics and influencing factors of multi-field precursor information such as stress, displacement, fissure, seepage, temperature and other multi-field precursor information during the water inrush process of mining faults in deep confined water.

Description

technical field [0001] The invention relates to the field of formation temperature and similarity simulation test, in particular to a similar test device and test method for evolution of multi-field precursory information of water inrush from mining faults in deep confined water. Background technique [0002] my country is rich in coal resources, but the geological conditions are complex, which makes geological disasters occur frequently in coal mining. With the increase of coal mining depth and mining intensity, the working face is increasingly threatened by the underlying Austrian lime karst water, especially the deep fault-bearing working face, the water inrush prediction and prevention problems are more prominent. [0003] Fault water inrush is an important form of water inrush in coal mines, which is highly hidden and difficult to determine. It is easy to cause major water inrush accidents and seriously threaten the safety of coal mine production. According to statisti...
