With the increasing progress of large-scale mechanized construction of long tunnels, how to choose the matching three-arm rock drilling rig for excavation, how to use reasonable and optimized technical solutions to solve technical problems in various specific situations, and achieve the effect of

The drilling process of mining brings a lot of dust pollution. Dust with particles smaller than 10 μm is difficult to settle to the ground after being discharged into the atmosphere, and has a strong adsorption force. Many harmful gases, liquids, and heavy metal elements can be adsorbed on it.

There are problems exsiting in a drilling process of hydraulic rock drill，for example，the front end cover becomes loose，rotary pressure can not be tested，impact piston strains and the drill does not impact.In order to improve drilling efficiency of imported drilling jumbo in downhole production

The performances of Rocket Boomer353 rock drilling jumbo and AMV21SGBC-CC full computer rock drilling jumbo are compared. Through the actual construction process, the applicability of the two kinds of rock drilling jumbo is analyzed.
