1. Control principle
Computer-controlled rock drilling jumbo
Uses an onboard computer and drilling software.
Drilling parameters (hole position, depth, angle, feed force, rotation, impact) are set digitally.
Can execute automatic or semi-automatic drilling according to a drilling pattern.
Remote-controlled rock drilling jumbo
Operated manually via a wired or wireless remote controller.
Operator controls boom movement and drilling actions in real time.
No automatic drilling logic; relies on operator experience.
2. Drilling accuracy
Computer-controlled
Very high accuracy (hole position deviation often ≤ 2–3 cm).
Drilling follows pre-designed blasting or bolting patterns.
Consistent hole depth and angle.
Remote-controlled
Accuracy depends on operator skill.
Greater variation in hole depth and alignment.
More difficult to maintain uniform drilling patterns.
3. Automation level
Computer-controlled
High automation:
Automatic collaring
Automatic drilling
Automatic stop at preset depth
Some models support data recording and pattern optimization.
Remote-controlled
Low automation.
Operator must control:
Boom positioning
Drilling start/stop
Hole depth judgment
4. Safety
Computer-controlled
Operator works from a protected cabin.
Less exposure to rock falls, dust, vibration, and noise.
Safer for long tunnel operations.
Remote-controlled
Operator can stand away from the face, improving safety compared with manual controls.
Still requires continuous attention and proximity in some cases.
5. Productivity
Computer-controlled
Higher drilling speed and efficiency.
Shorter drilling cycle time.
Ideal for long tunnels and large-section projects.
Remote-controlled
Moderate productivity.
More suitable for small tunnels or variable geology where flexibility is needed.
6. Skill and training requirements
Computer-controlled
Requires trained operators familiar with software and drilling plans.
Higher technical skill requirement.
Remote-controlled
Easier to learn.
Skilled operators can adapt quickly to changing conditions.
7. Cost and maintenance
Computer-controlled
Higher initial investment.
More complex electronic systems and sensors.
Higher maintenance and troubleshooting requirements.
Remote-controlled
Lower purchase cost.
Simpler system.
Lower maintenance cost.
8. Typical applications
Computer-controlled rock drilling jumbo
Long railway and highway tunnels
Hydropower tunnels
Projects requiring high blasting accuracy and repeatability
Remote-controlled rock drilling jumbo
Small to medium tunnels
Mine roadways
Projects with frequent geological changes or limited budgets
