Description

Technical field

[0001] The invention relates to a mining equipment, in particular to a concrete mixing and filling equipment with a small volume and flexible movement used in the construction of a mine tunnel and a coal mine underground concrete building. Background technique

[0002] With the development of society and economy, the construction of concrete buildings is becoming more and more complicated. For example, pillarless mining techniques such as leaving roadways along goafs in coal mines and backfilling mining require concrete filling construction. Construction equipment that is small in size, flexible in movement, convenient in installation, and capable of mixing and conveying concrete is required.

[0003] The current mining concrete equipment is a simple combination of existing concrete pumps and gap mixers. The equipment is huge, with a total installation height of 3.5 to 4 meters. It can only be fixed and installed. Sometimes the space needs to be expanded during inst...
