This series of deep-hole high-pressure water injection equipment is specifically developed for low-permeability, high-hardness coal seams in underground coal mine mining faces. It integrates high-pressure water injection, gas drainage, coal seam lubrication, and hydraulic coal cutting functions, serving as a core solution for water injection coal seam management. The equipment adopts a modular, integrated process, utilizing high-pressure water flow to achieve coal wetting and loosening, dust suppression, and in-hole cavity formation, thereby improving work efficiency. It integrates functions such as borehole flushing, drill bit lubrication, and hydraulic coal cutting, reducing process transitions. Equipped with high-power explosion-proof motors and an intelligent hydraulic system, it delivers high output pressure, ample flow, and low energy consumption. The compact, integrated structure includes high-pressure pump units, water and oil tanks, and control units, capable of delivering media like clean water and emulsion. This makes it a comprehensive solution for coal mining and gas control.
