In the field of mine filling engineering, before filling a filling empty area, a filling pipe network system needs to be subjected to water filling and pipe moistening in advance so as to prevent viscous filling slurry from being bonded on the inner wall of a pipeline to cause large conveying resistance; after the filling operation is finished, a water pipe is required to be filled into the pipe network system, so that the phenomenon that the residual filling slurry with viscosity is bonded on the inner wall of the pipeline to cause pipe blockage is avoided.

Generally, when filling operation is carried out on a single empty area, staged filling operation, namely layered filling, is adopted, the purpose is to ensure effective drainage of bleeding water of filling slurry in the empty area, ensure the safety of a filling retaining wall and maintain a certain curing and consolidating time. This method of operation determines the need for intermittent filling of individual stopes.

However, the general mine concentrating mill works continuously for hours, and correspondingly, the concentrating tailings used for filling the main aggregate are continuously produced. The tailing slurry is conveyed to a deep cone thickener of a filling station for dehydration concentration and stirring preparation of filling slurry, and the most stable working state of the two process links also requires continuous feeding and discharging work. That is, the most stable working condition of mine filling requires continuous filling operation as much as possible to ensure the ordered, stable and continuous operation of each process link of mine production.
