[pdf] The higher the working pressure of the down-the-hole drilling impactor, the faster the rock drilling speed. Since the drill impactor is designed according to a specific pressure, it performs best only within a given design pressure range. If the impactor is not used within the designed pressure range, not only will it not. .
The impact energy of the down-the-hole drilling impactor must ensure the specific energy of the drill bit, so as to effectively break the rock, and at the same time obtain a more. .
Generally, when the impact energy is constant, the higher the impact frequency, the greater the impact power. However, the outer diameter of the impactor is constrained by the. The selection of down-the-hole drilling rigs mainly considers several factors, such as the diameter, depth, direction, angle and drilling accuracy of engineering blast holes, rock conditions, construction site conditions and construction period.
