Abstract

The invention discloses a construction method of a filling separation wall. The construction method comprises the steps of self-inspection, preparation, sand taking, burdening, stirring, conveying, pouring, cleaning and the like. When the filling separation wall is constructed, cement mortar and an accelerator in a certain proportion can be mixed and poured into a formwork from bottom to top in a layering mode and are rapidly coagulated, and the filling separation wall with certain strength is formed. The device can realize automatic sand taking, batching, stirring, conveying, pouring and cleaning cycle operation, and effectively adapts to different underground stope working conditions. The built filling separation wall has the advantages of being completely closed, high in strength, high in speed and the like, the labor intensity of workers and the building cost of the filling separation wall are greatly reduced, the production efficiency of a mine filling mining method is improved, and mining operation safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of underground filling in mines, and in particular relates to a construction method for rapidly building a filling partition wall by means of a mine filling partition wall building vehicle. Background technique [0002] Backfill mining has become the preferred mining method for underground mines in my country. The backfill mining method has the advantages of safe operation, low recovery loss rate, high comprehensive utilization rate of resources, protection of ecological environment, and reduction of geological disasters. As we all know, in the backfill mining method, a backfill partition wall must be erected around the goaf before underground backfilling to prevent the backfill slurry from overflowing, causing roadway blockage or loss of personnel and property. The main structures of the backfilling separation wall filling mining method directly affect the filling effect, and it is the premise of improving the resou...
