Lava Flow Mine

The Lava Flow Mine is an area first released along with the quest King of the Dwarves on 4 January 2011. Later, a training area associated with the mine was released on 16 May 2011. It is a place for players to train Mining quickly without gaining ores (though gems may be acquired) and by appeasing the Liquid gold nymph players may attain pieces of the Golden mining suit.

The Lava Flow Mine also acts as a Geothermal power plant, using Gielinor's thermal energy (the lava) to turn water into steam, which in turn operates the various mechanisms around Keldagrim.

History
Located in Keldagrim, the Lava Flow Mine is used as the primary power source for the city. It creates steam, on which many of the city's machines work (similar to the Blast furnace). It is a vital part of Keldagrim - the Green Gemstone Director calls it the single most important piece of machinery in Keldagrim.

At the start of King of the Dwarves, a Cloaked figure blows himself up in the mine, causing a cave-in, which wounds six of the miners. He blows up the secondary boilers only, and black guard troops come to fix them very soon. They leave the miners under the rubble, for the player to mine them out. If the boilers weren't fixed, they might have exploded, causing further deaths and leaving most of Keldagrim without power for days. After the quest it seems 3 of the 6 miners have died, 2 died immediately, and 1 more died of his wounds later on.

During the quest the Blue Opal Director reveals how the lava flow mine works. The lava comes from the sub-Barendir magma vent. It is siphoned off from this vent and run along channels in the mine. The lava heats water in primary boilers over the channels, and the steam created is channeled into seven secondary boilers in the centre of the mine. From here, the steam is pushed through distribution vents to the various machines around Keldagrim, such as the mine carts and the blast furnace.

Location
The Lava Flow Mine is located through an opening on the east wall of Keldagrim. The easiest way to get there is by using the mine cart from the Grand Exchange to travel to East Keldagrim, and then run northeast.

Requirements

 * Completion of King of the Dwarves
 * 68 Mining
 * Any pickaxe, the higher the better

Suggested

 * Hammer (spawns near mine entrance)
 * 80 Smithing (for fixing boilers)
 * Amulet of glory/Ring of wealth (increases the chances of finding gems)
 * Gem bag
 * Ghostspeak amulet or Cramulet to speak to the ‎Dwarven ancestor spirit (However not needed just hitting continue on the Dialogue will still reward the +10% exp for 10 minutes)

Mining
The main purpose of the Lava Flow Mine is to mine off crust from one of the four lava flows. Foreman Jaak will say which of the four lava channels needs the most attention, which will also yield the most mining experience per successful cut off the crust. You can check the steam gauges next to each channel segment to see the flow in that segement - the segment with 50% flow gives the most experience.

After a while, the best flow changes, you will recieve a message in your chatbox when this happens. Jaak will know which one yields the most experience again. Unless the world is fairly full, it is advised to talk to Jaak instead of finding the correct flow yourself, because finding it with too few people might take too long. The segments next to the one with 50% flow will have 60% flow, and the next segments 70% flow and so on. This can help in finding the best segment to mine

When mining the best channel segment, one successful cut yields 100 experience when the exact correct part of the correct flow is mined. Experience gained is proportional to the flow in that segment, as shown in the table below.

Distractions
There are multiple distractions that can occur while mining the crusts. You will get a message in your chatbox in red when any of the distactions occur.
 * Gems - Like other types of mining, there is the chance that gems will be found.
 * Players_repairing_a_broken_boiler.pngBoiler breakages - As a result of the chaos dwarf attack, the boilers overheat. Repairing them takes a random Smithing level (70 to 90) and a hammer, which spawns at the mine entrance. If you fix it you will gain Smithing experience based on the required level. To see how much experience you would get when repairing a boiler, see the calculator to the right. You can only repair one boiler per hour.
 * This formula is $$150 * Smithing Level -7500$$
 * TzHaar hero - If players can slow down the lava monster long enough for the TzHaar hero to catch it, everyone inside the mine will be twice as likely to find gems for the next ten minutes.
 * Possessed pickaxe - The Dwarven ancestor spirit will take control of a nearby pickaxe. If the pickaxe is defeated, the ancestor will grant a 10% Mining experience bonus for ten minutes.
 * Liquid Gold Nymph - When the liquid gold nymph appears, she will give you a piece of the golden mining suit. If you already have a full set of the outfit, she will offer you Mining experience or gild any single pickaxe you have in your inventory (not including the Inferno Adze).

Maximising xp rates
To maximise xp rates while in the Lava Flow Mine, you must be mining the segment with 50% flow. This can be quickly identified by firstly finding the channel with below 100% flow, or talking to Foreman Jaak to be told which channel letter is slower, and then moving along it until you find the 50% flow, once here, you should begin mining. Stealing Creation Pickaxes can be used to increase xp rates, while Stealing Creation Hammers can be used to repair the boilers, both offering double xp for work in the mine. Penance Horns however, do not offer bonus xp.

The current maximum xp is around 40k/hr at lvl 99 with a good team and a lava titan.

Golden mining suit
In addition to the Mining and Smithing experience obtained by contributing to the mine, the Liquid Gold Nymph will randomly reward players with pieces of the Golden mining suit. Wearing all five pieces gives a 2.5% boost to experience while Mining, similar to the effects of the Lumberjack clothing set.

Gilded Pickaxes
The Liquid gold nymph will also trim the pickaxe in the players inventory, if they have acquired the complete Golden mining suit. Foreman Jaak can remove the gilding on any of the pickaxes.
