In order to meet the needs of large section roadway hard rock tunneling, through a variety of machine assembly program for analysis, the EBZ318（H）-based hard rock digging machine cut rock was ultimately settled, then used shuttle tramcar cache gangue the fully mechanized equipment supporting the operating line, and mechanized excavation machine with shuttle car's lap, and the small tanker shuttle tramcar lap optimized for improvements. In the large section hard rock digging mechanized line test，the technology achieved good results and improved ergonomics and a single heading into the level, speeded up the progress of the project to develop, which provided a guarantee for stable and healthy development of the mine.
