technical field [0001] The invention includes the technical field of rock mechanics experiment, and specifically includes a hydraulic coupling experiment device and method with CT real-time scanning. Background technique [0002] At present, my country has entered the stage of deep mining. Groundwater has a strong impact on the stability and deformation of coal and rock mass in deep mines. Mine disasters caused by groundwater are also common. Coal mine underground water can change the physical and mechanical properties of coal and rock mass. Therefore, it is imminent to study the influence of water on the mechanical properties of coal and rock mass and its effective prevention and control. [0003] Aiming at the hydraulic coupling engineering problems of coal mine water permeability and coal pillar water immersion, the damage evolution law of coal and rock mass under water immersion environment is studied. However, most of the current research is to measure its mechanical pro...

AI Technical Summary

Problems solved by technology

[0003] Aiming at hydraulic coupling engineering problems such as underground water penetration in coal mines and coal pillar immersion, the damage evolution law of coal and rock mass in a water-soaked environment is studied. However, most of the current research is to measure its mechanical properties after immersion out of the liquid and water pressure environment, and it is impossible to truly restore the water-soaked coal. Due to the mechanical properties of the rock mass and limited by the experimental conditions, it is impossible to observe the mesomechanical failure characteristics of the coal and rock mass in real time. Therefore, it is necessary to develop a hydraulic coupling test device with a CT real-time scanning system.
