Ultimate Mining Tycoon Explosives and Obsidian Guide
Blast tunnels, clear Obsidian walls, and deepen The Mine without wrecking your best ore veins.
Pickaxes carve ores; explosives reshape The Mine. In Ultimate Mining Tycoon (Innovation Inc., v0.5.13), dynamite and C4 open vehicle-sized tunnels, clear worthless stone, and are the only way to destroy Obsidian chunks added in v0.5.0. This guide covers where to buy explosives, how charges and cooldowns work, when to skip tiers, and how to blast without deleting Unobtainium clusters.

Why explosives matter
| Use case | Benefit |
|---|---|
| Deepen shared tunnels | Faster group progress to valuable layers |
| Vehicle access | Hole large enough for Super Crawler / Exa-Drill |
| Obsidian walls | Pickaxes and drills cannot break Obsidian |
| Clear junk ores | Free backpack slots for higher tiers |
| Factory Explosive Maker | Craft charges from processed metals (late) |
Explosives destroy ores in the blast radius — they do not add them to your inventory. Aim at stone and Obsidian, not at your best vein.
Finding Madattak’s Dynamite Shack
The shack is not next to Generico Mining Gear.
- Go to the spawn / plot area near global leaderboards.
- Find the uphill road away from the main shops.
- Follow signage for Madattak’s Dynamite Shack (field with crater props nearby).
- Buy dynamite / C4 tiers from Madattak’s inventory.
If you cannot find it, ask in chat or check the Official Links Discord map tips — the shack sits on a side road adjacent to the plots, not inside The Mine entrance.
How to place explosives
- Purchase and equip an explosive (appears next to your pickaxe in hotbar).
- Enter The Mine and aim at a stone or Obsidian face.
- Click / tap to place. Higher C4 tiers show charge bars (green segments) near the cursor.
- Only one active placement per player at a time.
- Charges refill on a cooldown (commonly cited ~20 seconds per charge for multi-charge C4). Dimmed charges mean you must wait.
Mobile players: equip the explosive first — v0.5.x fixed placement bugs when the item was not selected.
Explosive tiers (what to buy)
Exact stats shift between patches; use this as a priority ladder, then verify in-shop numbers.
| Tier | Type | Role |
|---|---|---|
| Early | Dynamite / Bundle | Surface and shallow tunnel opens |
| Mid | C4 Level 1–2 | Bedrock / Deep vehicle tunnels |
| Late | High C4 | Underworld rock + Obsidian |
| Robux | Nuke (~199 Robux, single-use) | Huge radius; chat announcement; skip if F2P |
Skip traps: Some mid bundles cost almost as much as the next C4 with tiny radius gains. Prefer one clear tier jump over every shop SKU.
Nuke notes
- Purchased in Robux Equipment store (not Madattak cash ladder).
- Single use per purchase — not a rechargeable charge pool.
- Announces in server chat when placed.
- Extremely large power/range — easy to erase valuable ore clusters. Use for blocked team tunnels, not for casual mining.
Obsidian rules (v0.5.0+)
| Fact | Detail |
|---|---|
| Break method | Explosives only |
| Pickaxes | Cannot mine Obsidian |
| Drill vehicles | Stop / blocked by Obsidian walls |
| Spawn | Large chunks in deeper mine zones |
| Role | Obstacle, not a sell ore |
When your Exa-Drill or Mini-Muncher hits Obsidian, stop drilling, place C4 on the wall, detonate, then resume. Trying to “pickaxe through” wastes time.
Blast etiquette in multiplayer
The Mine is shared:
- Do not trap players in sealed blast chambers.
- Warn before Nukes.
- Prefer blasting dead-end stone over active farming walls where others are filling Super Crawlers.
- Leave ramp access to surface — collapsed or sealed ramps anger the lobby.
Explosive Maker in the factory
Late factories can craft explosives via the Explosive Maker machine instead of only shopping Madattak. Feed it metal products from your Factory Chain Reference spine. Early game: buy charges — crafting opportunity cost is usually higher before electronics are stable.
Progression pairing
| Depth focus | Explosive plan |
|---|---|
| Surface–Shallow | Optional dynamite; pickaxe enough |
| Bedrock–Deep | Mid C4 for vehicle ramps |
| Crystal–Underworld | High C4 always equipped |
| Prestige rebuild | Rebuy cash explosives; Nuke is Robux |
Combine with Early Game Money so charge costs never bankrupt your first factory.
Safety checklist before you click
- Scan for high-value ore colors in the blast sphere.
- Confirm teammates are not standing in the radius.
- Ensure you have a path back to the unloader after the hole opens.
- Keep backpack space — after a blast, new ore faces appear fast.
- Do not place a second charge until the first resolves.

Frequently Asked Questions
Quick answers to the most common questions.
Can pickaxes break Obsidian?
No. Obsidian (v0.5.0+) can only be destroyed with explosives. Drill vehicles also stop at Obsidian walls.
Where do I buy explosives?
Madattak's Dynamite Shack on the uphill side road near the plots — not next to the main pickaxe shop.
Do explosives collect ore?
No. Blasts destroy blocks and ores in the radius. Use them to open tunnels or clear junk, not to farm Unobtainium.
Is the Nuke worth Robux?
Only if you need a single massive clear. It is single-use, announces in chat, and can wipe valuable veins if aimed poorly.
Why can't I place another C4?
Only one active placement is allowed, and multi-charge C4 must refill charges after use. Wait for green charge segments to return.
