Abstract
The differences between excavator-mounted rock drills and hydraulic rock drills:
The drill rig, designed for excavation and rock drilling, is mounted on an excavator and is primarily used for blasting in various stone works, as well as anchoring and support tasks and mineral exploration operations. This drill rig can also employ a casing-following method to maintain borehole stability while drilling grouting holes for hydropower cofferdams, seepage-control grouting holes in embankments, foundation reinforcement grouting holes, and anchor holes, among other applications.
The hydraulic rock drill for excavation and modification is a high-tech product powered by hydraulic oil, suitable for drilling into hard, medium-hard, and soft rocks alike. It offers a drilling diameter ranging from 32mm to 64mm. Key advantages include low energy consumption, compact size, lightweight design, substantial impact energy, rapid drilling speed, minimal noise, reduced vibration, and significantly lower labor intensity. This versatile tool is widely used in mining operations such as marble, granite, metal mines, non-metallic mines, and coal mines. Additionally, it proves invaluable in geological exploration, tunneling projects, and applications like drilling blast holes in construction sites, ports, hydroelectric facilities, road and bridge projects, as well as defense-related engineering endeavors.
A hydraulic rock drill uses high-pressure oil as its power source, driving a piston to deliver powerful impacts on the drill bit. The piston moves back and forth under valve control (though some models are valveless). Hydraulic rock drills offer several advantages: they achieve faster drilling speeds, deliver greater torque, operate at higher frequencies, produce superior impact energy, consume less energy, and maintain high efficiency.
Hydraulic rock drills have a long service life, and the incidence of drill jamming accidents is also very low.
Advantages of both the excavation-modified rock drilling rig and the hydraulic rock drill:
1. Highly versatile: Can be easily installed on hydraulic excavators of any brand.
3. High Return on Investment: Achieves rapid work efficiency with low fuel consumption, helping to save on labor and energy costs—for instance, the drilling speed for a 90mm hole can reach up to 1.2 meters per minute.
4. High Cost-Effectiveness: Rock-drilling excavator = drill rig + excavator, rivaling imported full-hydraulic drill rigs.
5. High Safety: Low risk of accidents, environmentally friendly operations.
6. Precision Computer Control: Intelligent control, simple operation.
