down-the-hole drilling rig Research and Application of Dry Dust Removal System for Surface DTH Drilling Rig 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.
open pit mine Discussion on Management and Maintenance of DTH Drilling Rig in Open-pit Mine Many industrial raw materials and one-time energy sources are derived from mineral resources. The development and utilization of mineral resources has become a favorable support for domestic economic development. In the process of mining open pit mines, down-the-hole drilling rigs are usually used
Hydraulic rock drill Technical Transformation and Application of HLX5-type Hydraulic Rock Drill 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
rock drilling jumbo Suitability analysis of two rock drills in operating process 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.
