End slope mining goaf filling machine and filling method thereof

Abstract

The invention discloses an end slope mining goaf filling machine and a filling method thereof, and relates to the technical field of coal mine goaf gangue filling. The end slope mining goaf filling machine comprises a crawler walking part, a machine body, a driver control room, a hydraulic pump station, an upper push plate mechanism and a lower push plate mechanism. According to the disclosed theend slope mining goaf filling machine and the filling method thereof, roadways and large-section goaf after open-pit mine end slope mining can be filled, automatic goaf roadway filling is realized, and compacting and solidifying operations on filling materials can be carried out, so that the filling rate of the filling materials is ensured, the top contact rate of the filling materials is improved, the filling effect is enhanced, the problems of uneven filling, roof descending and the like are effectively prevented; and meanwhile, the filling machine is high in maneuverability, can be used incooperation with other conveying and filling equipment for open-pit mine end slope mining, further saves the filling cost, improves the filling effect, and has high innovativeness and wide practicability.

Description

technical field [0001] The invention relates to the technical field of gangue filling in goafs of coal mines, in particular to a goaf filling machine for end-side mining and a filling method thereof. Background technique [0002] A large amount of pressed coal is formed on the side of the open-pit mine after mining, and this part of the pressed coal is often a great waste of side resources because it cannot be recovered in a timely and effective manner. It is of great significance to increase the economic benefits of enterprises and reduce the damage to the ecological environment. Gangue is a derivative of open-pit coal mining. Filling with gangue and other materials is an effective way to control the goaf of open-pit mine roadways. After the goaf roadway is filled, it can effectively reduce the bearing capacity of the coal pillar, maintain the stability of the gob and slope, avoid waste of resources, and further safe and efficient mining of side-side pressure coal has impo...

AI Technical Summary

Problems solved by technology

[0005] However, in the above-mentioned prior art, only mining and filling are carried out for the mining area, and the filling effect is limited. There will still be a phenomenon of poor roofing rate at the top of the goaf, and high-intensity compaction operations cannot be performed, making it difficult to form effective filling. The filling rate is low, the filling effect is not good, and it is easy to cause the roof to sink. It is difficult to apply to the large-section goaf after the end-side mining of open-pit mines, and the end-side coal pillar resources cannot be recovered in a timely and effective manner, resulting in waste of resources.
