Mining light concrete filling construction device

Abstract

The invention relates to a mining light concrete filling construction device. The mining light concrete filling construction device is characterized in that a main body structure of the mining light concrete filling construction device comprises a closed material turnover device, a closed pulping system and a main control conveyor, wherein the closed material turnover device is used for bearing and conveying cement dry powder, the closed pulping system is used for stirring the cement dry powder into cement paste, and the main control conveyor is used for mixing the cement paste with foam to generate foam concrete and outputting the foam concrete outwards. The mining light concrete filling construction device can be used for underground mine filling construction, is low in comprehensive cost and can be applied to underground mine filling and ground concrete filling. The construction device is light in weight, compact in boundary dimension, suitable for flexibly moving in a mine hoisting cage and a roadway, capable of being used in a combined connection mode and capable of reaching stopes near all the rail roadways for filling construction operation.

Description

technical field [0001] The invention relates to the technical field of underground mine filling mining method construction, in particular to a mining lightweight concrete filling construction device. Background technique [0002] At present, in the field of underground mining, the construction methods of mining filling mainly include different processes such as dry filling, tailings hydraulic sand filling, and tailings cemented filling; among them, dry filling has no mechanized construction equipment support, and mainly relies on manual construction in the stope , the labor intensity of workers is high, the operation efficiency is low, labor-intensive and time-consuming, and the filling body is semi-loose gravel, the surface smoothness and support stability after filling are insufficient, which in turn affects the firmness of the overall structure underground, and there is a construction safety problem. Hidden dangers; tailings hydraulic sand filling and tailings cemented ...

AI Technical Summary

Problems solved by technology

However, because the underground space for mining construction is very narrow and limited at present, and the existing foamed concrete equipment is bulky in shape and weighs several tons, it is inconvenient to transport and install, so the current foamed concrete surface filling equipment cannot enter the mine at all. Unable to realize construction operations in limited underground space

[0004] In view of the above, the scientific and reasonable transformation of the existing foamed concrete surface filling equipment, so that it can directly enter the mine roadway for mobile construction and complete underground filling operations, can not only be used as a supplement and replacement for the traditional mining filling construction method, the most critical It can also effectively solve a series of problems in the traditional mining and filling construction methods, such as high labor intensity, low operating efficiency, poor support stability, high investment cost, and the inability of the filling system to work underground.
