The blast mine is located in the northern section of Lovakengj. Blast mining is an activity which grants Mining and Firemaking experience.

Blast mining requires level 43 Mining to participate, as well as a chisel, tinderbox, and dynamite. Dynamite can be made by combining volcanic sulphur, juniper charcoal, saltpetre, and a pot, then adding a ball of wool to the resulting dynamite pot. Alternatively, dynamite can be purchased for coins from Thirus nearby.

Players use dynamite to blast chunks of valuable ores from within hard rock, which must then be washed before the chunks disintegrates.

Location

Players can quickly reach the blast mine by using the jewellery of jubilation teleport on the Kharedst's memoirs or book of the dead to teleport just south of the mine. Players can also use the Xeric's inferno option on the Xeric's talisman, and run north.

Bank chests

There are four bank chests in the area, which players can use to retrieve dynamite as needed, and deposit collected ores.

Gameplay

The dynamite explodes, blasting rock out of the cavity.

Players must first excavate 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 two squares away from it, or take about 15 damage.

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 three minutes to deposit the blasted ore before it disintegrates, so it is important to be quick. When there are at least 900 of any single type of ore in the sack, it will become full and the player will need to collect it before being able to excavate any more; the nearby operator will notify them of this. Players can talk to the brown-haired operator on the east side of the machine to collect the ore they mined in noted form, along with Mining experience according to the ores obtained.

Excavating the hard rock earns 20 Mining experience, and lighting the dynamite earns 50 Firemaking experience. Additional Mining experience is awarded along with the cleaned ores.

The blast mine is unique in that it enables players to obtain ores as if their Mining level were 10 levels higher; temporary boosts work, and must be active before the blasted ore spawns. For example, a player with 75 Mining can obtain runite ore here. The experience gained per hour varies depending on Mining level and overall efficiency. Additionally, players who have completed the elite Kourend & Kebos Diary have a 10% increased chance to obtain higher-tier ores.

Ore	Base experience
Coal	33
Gold ore	66
Mithril ore	120
Adamantite ore	190
Runite ore	260

Assuming 330 dynamite used per hour, at level 70, players can expect approximately 55,000 Mining experience and 310,000 coins per hour. This scales up to 88,000 and 800,000 respectively at level 99, with the profit increasing significantly at level 75 with runite ore becoming available. In addition, Firemaking experience is gained at 16,500 per hour, which does not scale.

Including the excavation, each dynamite is worth approximately 198 experience at 75 Mining and 264 experience at 99.

Unlike level boosts, the prospector kit 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.

Strategy

Main article: Blast mine/Strategies

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.

These are much easier if a consistent strategy is used. There are many patterns that may be used, with some variation keeping the above points in mind.

Only a chisel and tinderbox are required for the activity. A pickaxe is not used, though the special attack of a dragon pickaxe or higher as well as celestial ring slightly increase experience and profit. Graceful outfit is highly recommended, and some run energy restoration (such as stamina potions) is useful for some patterns as they slowly drain run energy.

Trivia

• 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" and that "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.
