Abstract

The invention discloses a water bursting test device and a test method thereof. The device comprises a water tank and a model box, a water storage tank is arranged at the bottom of the model box, a plurality of monitoring elements are arranged on the outer wall of the model box, and variable channel partition plates and partition plates are arranged on the top of the water storage tank; a water permeable plate is arranged on the upper surfaces of the variable channel partition plates and the partition plates; a pressure pump and a constant-pressure valve are connected between the water tank and the water storage tank through a water injection pipeline; a pressure meter is arranged on an outlet pipeline of the pressure pump, a heating device is arranged on the inner side of the bottom of the water tank, and a plurality of water inlet holes are formed in the side wall of the water storage tank; a plate inlet is formed between the side wall of the water storage tank and the correspondingvariable channel partition plate, and a drainage valve is arranged at the bottom of the plate inlet. Water bursting phenomena at different test temperatures, different water pressures and different water bursting flow speeds can be simulated. The device can be used for water bursting tests of different test materials, and is simple in structure and complete in function.

Description

technical field [0001] The invention relates to a water inrush test device, in particular to a water inrush test device and a test method thereof, belonging to the technical field of hydrogeology research. Background technique [0002] Complex geological conditions are the difficulty for us to solve underground geological problems. For the occurrence conditions of groundwater, there are different forms of storage spaces and channels, including voids, fissures, and caves. Mine water inrush is a difficult problem to solve in mining engineering. It has the particularity and complexity of various sites. To study its working principle and solution, it is necessary to simulate the conditions and causes of various sites. In the prior art Generally, similar simulation tests of water inrush are carried out in the laboratory, but the simulation experiments basically adopt the plane stress model. However, the simulation experiments were all single-hole water injection, which did not t...

Problems solved by technology

However, the simulation experiments were all single-hole water injection, which did not take into account the influence of single water injection on the pressure inhomogeneity during the loading process, nor did it take into account the influence of the shape of the water inrush channel on the water inrush. In the process of mine mining, the underground depth can reach 300 ~700m, the underground temperature increases with the increase of buried depth. In the previous test conditions, there were few adjustable parameters, and the temperature of the test could not be adjusted, and the combined effect of temperature and pressure could not accurately and efficiently simulate the underground water inrush at various depths.
