Description

Technical Field

[0001] The utility model relates to the technical field of coal mine goaf filling, in particular to a slurry material forming die for coal mine goaf filling. Background Art

[0002] Coal mine goaf filling is an important mining technology. Its core is to fill specific filling materials into the goaf to support the rock layer, improve the ore recovery rate, reduce resource waste, and protect and improve the ecological environment of the mining area. The filling mining method is suitable for a variety of ore deposit conditions, especially those where the ore and surrounding rock are unstable and no large exposed surface is allowed, as well as ore deposits where the surface needs to be protected. By filling the goaf, the rocks on both sides of the goaf can be effectively supported, creating conditions for continuing the stratified mining above. At the same time, the filling material can also alleviate the mine pressure caused by the working face support pressure, improve the maintenance of the mining site and tunnels, and effectively reduce surface subsidence and deformation. A forming mold is required in the production of filling products.

[0003] However, the internal modules of the existing molds cannot be replaced, so the internal structure and shape of the product cannot be changed. When producing different products, it is necessary to purchase multiple molds for use, which increases costs.
