Description

Technical Field

[0001] The invention relates to the technical field of multi-way valves for conveying mortar, and in particular to a multi-way valve suitable for conveying mortar. Background Art

[0002] Backfill mining involves filling the goaf with filler material while ore is being dropped, transported, and processed. The purpose of backfilling is to support the rock on either side of the goaf and create a foundation for continued stratified mining above. It is suitable for deposits where the ore and surrounding rock are unstable and large exposed areas are not permitted; where the surface requires protection; where rare and precious metal or high-grade ores are present; where sulfide deposits are prone to spontaneous combustion; and where the mineral deposits have complex geological conditions.

[0003] Existing underground mines using the backfill mining method often have multiple main backfill pipelines, while the underground backfill branch pipeline network is even more extensive and complex. The main backfill pipe is disconnected from the sand holes below the filling station, and the main backfill pipe is disconnected from the branch backfill pipes when not in use. Flanges are used to connect the pipes as needed during backfilling of the goaf.

[0004] The current pipe connection between the main filling pipe and the filling station is labor-intensive, and the pipe cannot be changed during the filling process, which affects the filling efficiency. Summary of the Invention

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
