The paper covers developments of air rock drillers and rock-drilling jumbos in China and summarizes individual usage features and limits of rock drillers, rock -drilling jumbos and shield machines during the tunnel constructions, analyzing domestic market shares and developmental trend of

In this paper, through the description of the oil emulsification failure analysis and treatment results of the hydraulic system of the Atlas COP1838HD+ rock drill equipped with TBM, the arrangement and working conditions of this type of rock drill on the TBM equipment are different from those of

The drill and blast method has been widely used in low gas tunnel construction because of its advantages, which helps to ensure the safety of tunnel construction. Taking a low-gas tunnel project as an example, the preparation work, technical points, and gas control measures of the drill-and-blast

The original mining equipment in our mine is relatively backward, the workers are labor-intensive, the driving efficiency is low, and the safety cannot be well guaranteed. For this reason, high-efficiency trackless mining equipment such as new hydraulic rock drilling rigs has been introduced
