Epiroc Underground Mining Equipment: The 7-Step Checklist Before You Sign a PO

Who This Checklist Is For

If you're a project engineer or procurement manager at a mine, quarry, or tunneling operation, and you're about to specify a new Epiroc underground drill rig or hydraulic breaker—this is for you. I'm the guy who reviews every equipment delivery before it reaches the operation floor at our site. I've rejected roughly 12% of first deliveries in 2025 alone due to spec deviations. This checklist is what I use in those reviews.

There are seven steps here. Not all of them are obvious. If you follow them in order, you'll avoid the most common—and most expensive—mistakes I see.

Step 1: Match the Load to the Task—Not the Brochure

This sounds basic, but you'd be surprised how many purchase orders come across my desk with a machine that's technically within spec but wrong for the actual application. For example, an Epiroc Boomer series drill rig might be rated for a certain rock hardness, but if your face is consistently above that threshold, you'll burn through consumables.

What to check:

• Published UCS (Unconfined Compressive Strength) range vs. your average rock condition
• Hole size and depth capabilities vs. your blast plan
• Muck size and debris density if you're pairing with a breaker

I once received a batch of hydraulic breakers spec'd for a quarry that turned out to be handling quartzite—40% tougher than the brochure. The vendor said it was 'within industry standard.' We rejected the batch, and they redid it at their cost. Now every contract includes a mandatory site rock sample test.

Step 2: Assess Serviceability and Parts Availability—Not Just Price

People think expensive vendors deliver better service. Actually, vendors who have a proven service track record can charge more. The causation runs the other way. I've learned this the hard way.

I don't have hard data on industry-wide parts availability rates, but based on our 5 years of orders with Epiroc, my sense is that delays affect about 8-12% of time-sensitive breakdowns. For a critical primary drill rig, that means downtime. Real downtime.

Questions to ask before the PO:

• Where is the nearest Epiroc parts center to your site? (Stockholm, Johannesburg, Denver are major hubs)
• What's the guaranteed lead time for drifter rebuild kits?
• Does the dealer have a service van with common spares on board?

When we specified our last fleet of Epiroc Simba longhole drill rigs, we insisted on a local parts bin—$18,000 of pre-stocked consumables at the mine site. That alone cut our downtime by 34% in the first year.

Step 3: Look at the Total Cost of Ownership—Not Just the Quote

I now calculate TCO before comparing any vendor quotes. The $500,000 base price on a drill rig can turn into $750,000 once you add shipping, commissioning, training, hydraulic hose replacement cycles, and the cost of unplanned downtime. The $650,000 all-inclusive quote was actually cheaper in the long run.

Include these in your TCO calculation:

• Transport and insurance (especially for underground modules that need disassembly)
• Commissioning and operator training costs
• Consumable wear rates: drill bits, shanks, hydraulic oil filters
• Estimated hourly operating cost (fuel, wear, labor)
• Residual value after 5 years—Epiroc rigs tend to retain value better than most

The lowest-quote supplier's TCO is often the highest. I've seen a 15% lower initial quote turn into a 22% higher 5-year cost.

Step 4: Verify Automation and Remote Monitoring Fit

This one is easy to overlook. Epiroc's Rig Control System (RCS) is powerful, but not all versions integrate equally with your existing fleet management software. Don't assume it just works.

Checklist for automation readiness:

• What version of RCS is on the machine? Can it support future upgrades?
• Does it communicate with your mine's Wi-Fi or LTE network? (Older sites may need a repeater)
• Are remote monitoring and diagnostic features enabled out of the box?
• What's the subscription cost for Epiroc's MyEpiroc digital platform?

I wish I had tracked this more carefully on our first automated rig. The platform itself was fine, but integrating it with our existing dispatch system took 3 weeks and cost us $22,000 in consulting fees. Now every contract includes a compatibility test clause.

Step 5: Check the Safety and Compliance Certifications

This is non-negotiable, but I still see orders where the required safety cert wasn't spec'd up front. For underground mining, that's usually ATEX (in Europe) or MSHA (in the US). Epiroc equipment generally meets both, but the specific configuration matters.

According to ISO 9001 guidelines (iso.org), machine safety documentation must include a risk assessment for the intended environment. If you're operating in a gassy mine, you need an explosion-proof drifter. Standard models won't cut it.

Documents to request:

• Safety manual and risk assessment for the specific model
• CE / UKCA / MSHA certificate of compliance
• Fuel and hydraulic fluid type approvals (especially for enclosed spaces)
• Noise and vibration data (often overlooked, but critical for operator health)

Step 6: Validate the Fit with Your Existing Fleet and Infrastructure

Another common mistake: buying a machine that doesn't play well with what you already have. Epiroc breakers and drill rigs are modular, but not everything is backward-compatible.

Physical compatibility checks:

• Hydraulic hose connection types and sizes (thread vs. flange)
• Boom reach vs. drift width (underground clearance is tight)
• Electrical voltage and connector types (24V vs. 48V, etc.)
• Weight distribution on the tramming chassis (especially on older track)

I remember a delivery where the new Epiroc breaker didn't fit the existing hydraulic hoses—the threads were metric, everything else was British standard. That $18,000 adapter set and 2-day delay was entirely avoidable. Now we send a checklist to the vendor before the order.

Step 7: Look Beyond the Machine—At the Technology Roadmap

Epiroc is investing heavily in automation and electrification. Their partnership with ispace for lunar excavators in 2025 is a sign of their long-term R&D focus, sure, but it also means their core mining equipment is evolving fast. If you're buying a new drill rig today, think about whether it can be retrofitted with next-gen automation modules 3 years from now.

Questions to ask the Epiroc sales engineer:

• Is this model compatible with future RCS 4.0 or upgraded telemetry?
• Are there upgrade paths for electric drivetrains or hybrid systems?
• Will spare parts be available for at least 10 years? (Standard for Epiroc, but verify)

If I were spec'ing a rig today, I'd pay the extra for the 'future-ready' package. On a $600,000 machine, an extra $12k for modularity is kinda a no-brainer.

Common Mistakes and What to Watch For

Mistake #1: Assuming 'heavy' means 'reliable'
Heavier machines may indicate over-engineering, but they also mean slower tramming and higher fuel consumption. Match the mass to the task.

Mistake #2: Ignoring the operator cabin
An Epiroc rig with a standard cabin may be fine for temperate climates. At 40°C underground, you want the premium AC package. Operators will thank you—and your productivity will show it.

Mistake #3: Overlooking the warranty terms
Standard warranties often exclude wear parts like drill bits and shanks. Read the fine print. I've seen buyers assume coverage on items that were excluded. Negotiate extended coverage on drifter and hydraulic components—it's worth the 3-5% premium.

One last thing: Prices quoted today may not hold past 60 days. Epiroc adjusts annually based on steel and shipping costs. Verify current pricing and lead times before you commit. Honestly, I'd check with your local Epiroc dealer right now—lead times on some underground drill rigs have stretched to 6 months in 2025.
