If you run an underground mining site, you get how key the proper gear is. A hydraulic drilling jumbo can change your work flow a lot. It deals with the hard task of cutting through stone to make paths and holes. But with lots of choices out there, how do you find one that suits your setup? This post guides you through it bit by bit. We look at what to check, usual mistakes, and advice from folks in the business. When you finish reading, you will know how to pick something that helps your place work better and keeps everyone safe.
What Makes a Hydraulic Drilling Jumbo Key in Underground Mining?
Mining below ground brings its own set of problems. Narrow spots, solid stone, and always pushing to meet goals. That’s when a hydraulic drilling jumbo stands out. These units make exact openings for blasts. And they help open new parts.
The Main Ideas
A hydraulic drilling jumbo is like a moving setup with arms that hold tools for breaking rock. It uses fluid power, which gives it strength to go through hard stuff. Many have one or more arms, so you cover ground quicker. See it as your main helper for starting and ongoing drilling. In slim tunnels, it has to move smooth without using extra power.
Workers like them for the handling they give. You can change the push and spin speed right away. This leads to neat holes and less stuck bits. Also, new ones lower sound and shaking, so long days feel easier.
Main Tasks It Does
Down below, these jumbos do front drilling to push tunnels forward. They also make spots for bolts to hold up the top, keeping things steady. In big sites, they might cut long holes for pulling out ore. The good one speeds your steps, from drilling to blasting and clearing debris.
Think about a spot where hold-ups build up fast. A fine jumbo cuts down stops by working quicker and right on target. It brings better blast outcomes, so less junk stone and more good ore. Safety improves too, since exact drilling means fewer shaky places.
Things to Think About When Picking One
Picking is not just about the cost. You need to fit the unit to your mine’s layout. Begin by looking at your path sizes and stone kinds. A bad match can cause breaks or slow jobs.
Size and How It Fits Your Paths
Path measures count a bunch. Check your cross areas well. For tiny paths, around 3 by 3 meters, go for a small jumbo with a tight turn. It gets into close areas without hitting sides.
Bigger paths may want longer arms for more reach. Look at the unit’s moving sizes too – how long, wide, tall when going. You don’t want it jammed in passages.
Here is a fast chart for size ideas:
| Path Cross Area | Suggested Jumbo Kind | Why It Works |
|---|---|---|
| Tiny (3×3 m) | Small, one arm | Simple turns, short height |
| Middle (4×4 m) | Two arms | Hits more front space |
| Big (5×4.5 m) | Strong, many arms | Deals with large blasts |
Test the fit in your real setup always. A jumbo too large burns fuel; too little, and you drill extra.
Strength and How It Drills
Strength sets how fast you cut. Check the rock tool’s hit power and how often. Tough stone needs more hit to break without slowing.
Spin force helps keep holes straight. Find a mix – power to go but not too much to get hot. Fluid setups should work well, saving on gas or power.
Think about the push way. Types with tubes or ropes give steady force. Speed while loaded shows real use. In checks, top ones reach 800 mm a minute or higher.
Don’t forget hole deep and width. For output, you may need deeper ones up to 3 meters. Match to your blast ideas.
Safety Parts That Protect People
Safety matters a lot below ground. Seek cabs with clear views and guards from falling stones. Easy controls cut tiredness, lowering crash chances.
Current jumbos have ways to lessen shake and noise. This holds workers alert. Auto stops for high push or low fluid avoid accidents.
Look for simple reach to fix spots. A unit easy to check means less time with folks in danger.
Money Thoughts and Lasting Worth
First price catches eyes, but look ahead. A low-cost jumbo might fail often, costing more to mend.
Looking at Costs
Add in buy price, but count running costs like fuel and bits. Good fluid ways lower power use, saving cash each day.
Fix times count. Reach from ground for daily looks keeps it going. Seek strong parts that last in dust and wet.
Sell-back worth matters. Solid ones keep value, so you switch without big loss.
Getting Top Value
Figure full own cost. Add teaching for your group – an easy jumbo means fast learn.
Points for smart buy:
- Check fuel use among choices.
- Ask on cover for big parts.
- Think about bit supply; waits hurt.
- See if it grows with your work.
A good pick returns in more output and less troubles.
Upkeep and Help Needs

No unit lasts without care. Choose one with easy upkeep to hold high run time.
Day and Usual Checks
Basic jobs like fluid swaps should take little time. Look for builds where filters and lines are close.
Normal care stops large problems. Fluid setups need clean stuff to skip blocks.
Help After Buy
Fine makers give teaching and fast bit send. Help at site fixes quick.
Pick a group with history in mining. They get your issues and give fit tips.
Green and Work Flow Sides
Mines get push to be clean. Good jumbos aid by using less power.
Lowering Bad Air
Power or mix kinds cut smoke in closed spots. Better air means fit workers.
Save-power parts like changing pumps set force as wanted, less waste.
Helping Whole Site Work Better
A quick jumbo shortens rounds. This lets loaders and hauls match, raising total out.
Link with other gear counts. Matching ways smooth jobs.
Tips from Real Mining Folks
Chat with others in the work. What fits one mine may not another from stone hard or damp.
Try drives show much. See how it takes your ground.
Keep up on new tech. Fresh jumbos often cut smarter with auto.
