A kind of mining lightweight concrete filling construction device

Abstract

The invention relates to a light-weight concrete filling construction device for mining. Dry powder, the closed pulping system is used to mix dry cement powder into cement slurry, and the main control conveyor is used to mix cement slurry and foam to generate foamed concrete and output it to the outside; the invention can be used for underground filling construction, and the overall cost is Low; it can be used in underground mine filling and ground concrete filling. The construction device is light in weight and compact in size, suitable for flexible movement in the mine hoisting cage and roadway, combined and connected, and can reach all the stopes near the track roadway for filling construction operations.

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 backfill mainly include dry backfill, tailings hydraulic sand backfill, and tailings cement backfill. , the labor intensity of workers is high, the operation efficiency is low, labor and time are consuming, and the filling body is semi-loose crushed stone, the surface flatness and support stability after filling are insufficient, which in turn affects the firmness of the overall structure of the well, resulting in construction safety. Hidden dangers; tailings hydraulic sand filling and tailings cemented filling are mainly based on the establishment of filling systems on the surface. After the filling bodies are produced on the surface, they are then input to the under...

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.
