The third connecting pipe 21 is connected between the second liquid storage tank 2 and the leaching tank 4, so that the liquid in the second liquid storage tank 2 can enter the leaching tank 4. The fourth connection pipe 51 is connected between the leaching tank 4 and the first liquid-taking tank 5, so that the liquid in the leaching tank 4 can enter the first liquid-taking tank 5.
The leaching column 3 is used for simulating surface water coming from an underground reservoir, and the leaching tank 4 is used for simulating crevice water from the underground reservoir. Specifically, rock samples are placed in the leaching column 3 and the leaching tank 4, liquid water is stored in the first liquid storage tank 1 and the second liquid storage tank 2, and in order to be more in line with the actual environment in this example, mine water is stored in the first liquid storage tank 1 and the second liquid storage tank 2. The liquid water in the first liquid storage tank 1 enters the leaching column 3 through the first connecting pipe 11, then enters the leaching tank 4 through the second connecting pipe 31 after passing through the rock sample in the leaching column 3.
