Abstract

The invention discloses a deep confined water mining fault water inrush multi-field precursor information evolution similarity test device and method, and relates to the field of formation temperatureand similar simulation tests. The test device comprises a test bracket, a lateral baffle plate, a loading plate, a transparent glass plate, a model storage cavity, a lateral pressure loading system,a vertical loading system, a water pressure loading system, a water temperature adjusting system, a ground temperature adjusting system, a signal acquisition and processing system and a test model. The water pressure loading system, the water temperature adjusting system and the ground temperature adjusting system of the test device can provide stable high-temperature and high-pressure water and gradient formation temperature for the test model; the real geomechanical environment of the deep confined water fault-containing coal measure strata can be well simulated; real reproduction of multi-field precursor information of deep confined water mining fault water inrush is facilitated, and the evolution rule, coupling characteristics and influence factors of multi-field precursor informationsuch as fault surrounding rock stress, displacement, cracks, seepage and temperature in the deep confined water mining fault water inrush process are inversely analyzed.

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 the evolution of multi-field precursor information of fault water inrush caused by mining in deep confined water. Background technique [0002] Our country is rich in coal resources, but the geological conditions are complicated, which makes geological disasters occur from time to time in coal mining. With the increase of coal mining depth and mining intensity, the working face is increasingly threatened by the underlying Ordovician lime karst water. Especially for the deep working face with fault structure, the water inrush prediction and prevention problems become more prominent. [0003] Water inrush from faults is an important form of water inrush in coal mines. It is highly hidden and difficult to determine. It is easy to cause major water inrush accidents and seriously threaten the safe production of coal...
