Abstract

The invention discloses a belt type compact coal mine paste filling device. The belt type compact coal mine paste filling device comprises a main material storage device, a belt conveyor, auxiliary material storage devices, a steel frame, a first floor, a second floor, a third floor and a fourth floor, wherein the first floor, the second floor, the third floor and the fourth floor are arranged inside the steel frame, the auxiliary material storage devices are fixed to the fourth floor, a metering device is arranged on the third floor, a stirring device is arranged on the second floor, and a slurry buffer device is arranged on the first floor. The belt type compact coal mine paste filling device further comprises a filling pump, a control chamber unit and an electrical control unit. The filling pump is arranged inside the steel frame, the control chamber unit and the electrical control unit are respectively of a container structure, and therefore the coal mine paste filling device is compact in structure, reduces the civil engineering work amount and saves construction time, the feeding method of main material is a belt type feeding method, the advantage of being small in occupied area is achieved, running power of the coal mine paste filling device is effectively lowered, and the aim of reducing cost of the coal mine paste filling device is achieved.

Description

technical field [0001] The invention relates to a mine goaf filling device. Specifically, it relates to a belt-type compact coal mine paste filling device. Background technique [0002] Coal mine goaf refers to the cavity or cavity left underground after coal and other ores are transported away in the process of coal mining. If it is not filled, it will cause ground subsidence and subsidence, making villages, pipelines, bridges and The railway is destroyed; the subsidence of farmland will cause large areas of water accumulation and land salinization, making it impossible to cultivate. In addition, the formation of coal mine gobs will also lead to environmental pollution, low recovery efficiency of underground resources, frequent accidents in coal mines, etc. . In recent years, coal mine paste filling technology has been gradually used to solve the above problems. The so-called coal mine paste filling technology refers to making coal gangue, fly ash, cement, water, municip...
