Excavation operation is an important proces in the excavation of tunnels and passages in metal and non-metalunderground mines, providing necessary channels and conditions for subsequent mining, ventilation, power supply, safetymanagement, and other work. It is an important link in mining. Therefore

This paper takes the Changyang Tunnel project of the newly constructed Yichang-Fuling High-Speed Railway in Hubei Province as the research object, and conducts a comparative study on the comprehensive effectiveness of fully computer-controlled three-arm rock drilling jumbos and traditional manual

The repair and remanufacturing of scrapped parts of fully hydraulic rock drills have a very good market prospect, fully complying with the national policies of circular economy and energy conservation and emission reduction. We look forward to manufacturing companies and parts repair exper

Investigate the application of the three-arm rock drilling jumbo and the handheld rock drill in the construction of the Funiu Mountain Shuanglong Tunnel exit section on the Zhengxi Expressway, and compare the applicability, construction cost, safety, energy consumption, and efficiency of the two
