Wet spraying concrete stirring station mortar manufacturing device and method in mine underground

The invention belongs to the field of mining machinery engineering, and relates to a wet spraying concrete stirring station mortar manufacturing device and method applicable to a mine underground. The mortar manufacturing device comprises an underground wet spraying concrete stirring station body, a wet spraying material conveying and metering adding system and an electric gas circuit control system; the wet spraying material conveying and metering adding system and the electric gas circuit control system are arranged on the underground wet spraying concrete stirring station body; various materials are mixed into concrete material mortar in proportion by the wet spraying material conveying and metering adding system; and the electric gas circuit control system controls running of the wet spraying material conveying and metering adding system. A wet spraying concrete stirring station is built in the mine underground, the distance generated when a concrete transporting tank car is adopted to transport wet spray
