The Blast Mine is located in the northern section of Lovakengj. Blast mining is a minigame, which grants Mining and Firemaking experience, and requires 43 Mining. Participating in the minigame requires 100% Lovakengj favour.
Blast mining requires dynamite, which is made from volcanic sulphur, juniper charcoal, saltpetre, and a pot, then adding a ball of wool to the resulting dynamite pot. Players will be using it to blast chunks of valuable ores from within hard rock.
Gameplay[edit | edit source]
Players must first excavate the hard rock using a chisel, then use a pot of dynamite on the resulting cavity. Then, they must light the dynamite with a tinderbox and run at least three squares away from it, or about 15 damage will be taken.
Once the dynamite explodes, players should collect the blasted ore from the ground and deposit it into an ore sack near a working operator. Players have one minute to deposit the blasted ore before it disintegrates, so be sure to deposit it immediately. When there are 450 of any single type of ore in the sack, it will become full and the player will need to collect it; the nearby operator will let the player know. Once the player is ready, they will be able to talk to the brown-haired operator to collect the ore they mined in noted form, along with Mining experience relative to the ores obtained.
20 Mining experience is granted for excavating the hard rock, and 50 Firemaking experience is granted for lighting the dynamite. The rest of the Mining experience is then collected along with the cleaned ores.
The Blast Mine is unique in the fact that players can obtain ores that are ten levels above their Mining level. This means a player with 75 Mining can obtain runite ores from the blasted ore. Boosts do work in obtaining ores, but it must be boosted before the blasted ore appears.
Strategy[edit | edit source]
To do Blast Mining efficiently, it is important to:
- Minimise the time wasted waiting for dynamite to explode.
- Minimise the time spent running to and from the deposit sack.
- Minimise the amount of damage taken.
This becomes much easier if a consistent strategy is used.
All the patterns in this article take a very similar amount of time per blasted ore. However, Pattern 1 is around 8% faster than any other pattern.
Pattern 1[edit | edit source]
One such strategy can be seen in the image to the left where the player moves from Spots 1 to 7.
Start by excavating and placing dynamite in Spots 1 and 2, then light them directly after each other, and run to Spot 3 (do not pick the ore up from the ground yet).
For Spots 3 to 6, simply excavate, place and light dynamite, and run to the next spot (do not pick up the ore). At Spot 6, light the dynamite as before and run and pick up the ore from Spot 4 and then pick up the ore from Spot 5. Make sure to stand at Spot 5 to avoid taking damage from the dynamite when it explodes.
Finally, pick up all of the ore left on the ground which should be (in the order they are picked up) 3, 6, 2, 1 and deposit them in the sack labelled 7.
The walls regenerate in time for you to start a new lap and no time is lost.
It might be a good idea to practice doing 3 to 6 before adding in 1 and 2 as you would risk that they disappear if you take too much time.
- Note: The reason Spots 3-6 are placed as they are is to make sure the player is always able to start excavating the next spot while waiting for the dynamite to explode. This is possible as the distance between each spot and the next is 3 squares meaning the player will not take any damage.
Pattern 2[edit | edit source]
Another possible pattern happens at the western part of the mine where the player moves from Spots 1 to 7 as well.
Start by excavating and loading spots 2, then 1. Then, light 1 and then 2 (do not pick the ore up from the ground yet).
Run to spot 4, and excavate 4 and 3. Then, light 3 and then 4.
Run to spot 5, and excavate 5 and 6. Then, light 6 and then 5. Now, pick the blasted ores up from spot 1 to spot 6.
Finally, deposit the blasted ores into the sack at spot 7.
This strategy uses less run energy, but is slightly slower than the strategy above.
Pattern 3[edit | edit source]
(This method requires constant attention to avoid ore disappearing or taking damage, but the timing isn't too precise)
Excavate 1-5 and then load 1-5, follow by lighting 5 and 4, then skipping 3 and light 2 and 1.
Run over to 6 and excavate and load, and then light 6 and then return to 3 and light 3.
Then run over to and excavate and load 7 and 8 and then light 8 and 7.
Finally move over to 5 and pick up 5-1 while 8 and 7 explode and then move over to 6 and pick up 6-8.
Put all blasted ore in sack.
8 Ore Pattern[edit | edit source]
(Note: this method is around as fast as the "pattern 3" method, however, it is considerably harder and consumes more run energy.)
By alternating between excavating, loading, and blasting it is possible to mine up to 8 ore in a single sequence in the North-West of the mine.
Excavate Spots 1, 2, 3, and 4 (But don't load dynamite).
Go back and load spots 1 and 2.
Excavate and Load Spots 6 and 5.
Load Spots 3 and 4.
Ignite Spots 3 and 4.
Ignite Spots 1 and 2.
Ignite Spots 6 and 5.
Excavate and Load Spots 7 and 8.
Ignite Spots 7 and 8.
Collect Ore 6, 5, 4, 3, 7, 8, 2, 1.
Deposit at 9.
If done correctly the entire sequence should take 45 seconds from the time spot 3 is ignited leaving a 15 second buffer before any ore disappears. It's recommended to practice with just spots 1-6 until you're confident in the sequence to prevent ore from being wasted.
Experience rates[edit | edit source]
Estimated probabilities based on the data blasting 1000 dynamite at 75 Mining in November 2016. Experience per hour is calculated by assuming 300 dynamite blasted per hour.
|Ore||Base experience||Pieces||Confidence interval probability||XP/HR||GP/HR|
|Gold ore||60||368 (25%)||23%-27%|
|Mithril ore||110||469 (32%)||29%-34%|
|Adamantite ore||170||272 (18%)||16%-20%|
|Runite ore||240||118 (8%)||6.6%-9.4%|
Each dynamite is worth approximately 180xp (160xp from ores and 20xp from placing dynamite) at 75 mining, and a bit over 210xp at 99.
At level 70:
48k xp per hour with 310k gp per hour.
At level 80:
58k xp per hour with 427k gp per hour.
It should be noted that this large increase in profit is a result of gaining access to runite ore at level 75 - 10 levels lower than normal, a perk of using the Blast Mine.
At level 90:
64.4k xp per hour with 587k gp per hour.
At level 99:
69.8k xp per hour with 693k gp per hour.
It should also be noted that the Prospector kit from Prospector Percy affects the experience received while collecting the washed ore, it is not required to wear it while blasting ore and depositing blasted ore to obtain the bonus experience.
Changes[edit | edit source]
|23 February 2017
(update | poll)
It is now possible to place Dynamite into rock cavities at the Blast Mine via a left-click option, rather than having to use Dynamite on a cavity.
Trivia[edit | edit source]
- If the player speaks to the operator about the machine, they will state that it is used to quickly clean the blasted ores, and that the design is a secret, with those who try to copy it would "never get it quite right. I bet their machine would break down all the time." This is a reference to the fact that the struts on Prospector Percy's water wheel in the Motherlode Mine often break, while the blast mine's machine never breaks.
