The WPZ-75/1000 coal mine roadway rehabilitation machine integrates multiple functions, including excavation, lateral digging, inclined operation, rock breaking, loading, and lifting. It is capable of tasks such as digging drainage ditches, leveling roadways, breaking rock, clearing material from beneath conveyors, and performing localized ground leveling. With optional attachments—such as a hydraulic breaker, roof bolter, and bolt cutter—it can also execute rock breaking, bolt hole drilling, bolt/cable cutting, and the installation of specialized beam support devices. Additionally, it assists in loading and unloading U-shaped steel arches, enabling a single machine to complete all stages of roadway repair.
