Abstract

The invention discloses a test model for testing the sealing and anti-seepage between rock layers, which includes a test box, and a water-bearing similar rock layer is poured at the bottom of the test box; wherein, at least one artificial gap is formed on the water-bearing similar rock layer; At least one circle of grooves is also provided on the rock formation, and the artificial gap is surrounded in the groove; on the water-bearing similar rock formation, at least one circle of waterproof ring is arranged corresponding to the groove, and the waterproof ring includes the bottom of the waterproof ring and the top of the waterproof ring. The top of the waterproof ring includes a water-facing slope inclined towards the direction of the artificial gap and a backwater slope inclined away from the artificial gap; the bottom of the waterproof ring is located in the groove, and the top of the waterproof ring is raised on the water-bearing similar rock formation On the surface: a water-proof similar rock formation is poured on the upper surface of the water-bearing similar rock formation, and the top of the waterproof ring is located in the water-resistant similar rock formation. The invention also discloses a method for making the test model.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of mining engineering and water conservancy engineering, in particular to a test model and a manufacturing method thereof. Background technique [0002] The pattern of coal occupying the dominant position in my country's energy structure is difficult to change for a long time. At the same time, the environmental problems caused by the development and utilization of my country's coal resources have become increasingly prominent. On the one hand, the coal-rich areas in western my country are mostly in arid and semi-arid areas, where water resources are scarce and the surface ecology is fragile; on the other hand, mine water is unavoidable in the process of coal mining, and if it is not handled properly, it will not only cause damage to groundwater resources At the same time, it will also cause a series of hazards such as reduction of river runoff, depletion of water resources, land ...
