At present, most of the full-section drilling and grouting equipment adopts the pneumatic down-the-hole hammer single-arm multi-functional drilling rig, which has high cost, low efficiency, slow speed and large pollution. The three-arm rock drilling rig has a large operating range, flexibility

The paper outlines EPIROC’s COP MD20 hydraulic rock drill and analyzes its advantages in usage. This hydraulic rock drill is compared with COP 1838 in terms of structural features. The paper also assesses the technical road of double- side oil return system and the prospect of COP 1838 product.

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.
