Mining Underground Spray Machine (XYGP-PS6D/7D) integrates conveying and spraying functions, capable of transporting proportionally mixed materials such as cement, sand, and additives through the spray pipeline to the nozzle, where they are mixed with high-pressure water and sprayed at high speed onto the tunnel rock wall. This equipment controls the spraying pressure and flow through mechanical power, achieving uniform and continuous spraying, ensuring construction efficiency and quality.

Its core function is to reinforce the tunnel rock walls by forming a dense concrete layer on the surface of the rock walls through shotcreting, enhancing the stability of the surrounding rock, preventing collapses, and ensuring the safety of underground operations; it can also seal rock wall cracks, block the infiltration of groundwater and harmful gases, and improve the underground working environment; in addition, the smooth shotcrete layer facilitates subsequent pipeline installation and maintenance.

In terms of work scope, the mining underground shotcrete machine is suitable for the excavation support of various types of mines such as coal mines and metal mines, as well as tunnel repair and reinforcement projects; it can also play a role in tunnel construction and underground engineering chamber support; whether it is horizontal tunnels, inclined tunnels, or the top and side walls of chambers, shotcrete operations can be completed, making it an indispensable piece of equipment for mining and underground engineering construction.
