Embodiment
[0021] This embodiment provides a method for simulating goaf mining. The design principle of the method for simulating gob mining is: fill the pit with a rubber hose filled with a thin, flowable filling material, and overlying the rock formation, and then release the rubber hose. The filling material can be flowed to simulate the mining of the goaf.
[0022] In this embodiment, the hardware for simulating goaf mining is as follows: a main body with a pit, which provides installation locations for rubber hoses; several rubber hoses, each of which is filled with fine flowable filling materials, the number and radius of rubber hoses, etc. The specifications are determined according to the size of the pit, and the size of the pit is determined according to the size of the simulated goaf. The two ends of the rubber hose are knotted; the steel wire or iron wire is used to wrap the knot at both ends of the rubber hose and to fasten the two ends Sealing; hollow pipe, used to insert fl...
