Embodiment
[0021] This embodiment provides a method for simulating mined-out area mining. The design principle of the method for simulating mined-out area mining is: use a hose filled with fine flowable filling material to fill the pit, overlying the rock, and then release the hose Flowable filling material to simulate the mining of the goaf.
[0022] The hardware used in this embodiment to simulate goaf mining is as follows: a main body with a pit, which provides installation locations for the hose; hoses, several, each hose is filled with fine flowable filling material, the number and radius of the hose, etc. The specifications are determined by the size of the pit, and the size of the pit is determined by the size of the simulated goaf. The two ends of the hose are knotted; steel or iron wire is used to wind the knots at the two ends of the hose to fasten the two ends. Sealing; Hollow pipes are used to insert flowable filling materials into the hoses. The outer diameter of the hollow pip...
