Description

Goaf unloading filling device

Technical Field

The utility model relates to a collecting space area fills technical field, especially a collecting space area unloading fills device.

Background

The open stope mining method is suitable for ore bodies which are stable in ore rocks and the like, have obvious ore rock contact surfaces and are stable in shape. The open stope mining method is characterized in that an ore body is divided into an ore room and an ore pillar along the trend, and the stope is mined in two steps; when stoping the chamber, the top plate of the goaf is mainly supported by the stability of the ore rocks and the ore pillars; and after the stoping of the chamber is finished, stoping the ore pillars or not stoping the ore pillars in a planned way, and treating the goaf in time.

For the treatment of the goaf, filling slurry is generally adopted to fill the goaf. The filling slurry is prepared by mixing materials such as cement, fly ash, slag, phosphogypsum, water and the like according to specified granularity and proportion. The method for feeding the filling slurry into the goaf is to convey the filling slurry through a slurry discharging pipe in a self-flowing or pump station mode.

The blanking and filling modes adopted after filling slurry is sent to the goaf through the slurry blanking pipe are mainly two. 1. And (4) single-point blanking and filling, wherein the filling slurry is directly put into the goaf through a slurry blanking pipe. The method has the advantages of simple operation and low cost. However, when the adopted area with large span is filled, the defects that the filling slurry is easy to segregate and the strength of a filling body is uneven exist, so that the potential safety hazard of a surrounding stope room and an ore pillar is large in later-stage stoping, and the ore dilution rate can be increased. 2. The filling slurry directly enters the goaf for blanking and filling, and the method has the advantages of reducing the segregation risk of the filling slurry and having high filling body strength. But also has the safety coefficient reduction, and is easy to have the safety accident in the mine that the goaf span is big, roof-bottom plate and ore pillar are unstable.

Therefore, in the field of blanking and filling of an open stope mining method, in order to ensure the strength of a filling body, reduce the segregation of filling slurry, ensure the safety of mining operation and the like, the existing blanking mode and equipment still need to be improved and innovated.
