The Quarry is a machine added by BuildCraft. It allows for automatic mining of specified area. The Quarry can be powered with Minecraft Joules, commonely known as MJs. It can use up to 50mj/t to run at full mining speed and ejects items from its top face by default. Buildcraft pipes aswell as others can connect to the Quarry and will recieve items that it mines out.
Starting a QuarryEdit
The default frame of the Quarry will occupy an area of 11x11x5, and excavate a 9x9 area of land. These dimensions can be increased, up to 64x64. To adjust the size of the Quarry, three Landmarks will need to be placed in a square or rectangular pattern, then activated by right clicking one of them. Note that powering a Landmark with a redstone signal will emit a beam that will travel to the extent of where the following Landmark can be placed, 64 blocks, in all directions. The Quarry will then need to be placed next to one of the Landmarks. A black and yellow line will appear when the Quarry is placed. The line is where the frame will be built.  Upon starting, the Quarry will clear the area within the black and yellow bars and build a frame. Once the frame is complete, it will spawn a crane-like structure that will begin to mine the area one block at a time. These blocks will be deposited into any adjacent chest or pipe. If there is no chest or pipe, the mined items will be ejected from the top of the Quarry. There is no need for a Wooden Pipe to fetch the items; the Quarry will place the items into a connected Stone Pipe, Cobblestone Pipe, Gold Pipe, Iron Pipe, or Diamond Pipe.
In the event the quarry encounters lava, the rest of the blocks under the lava will not be mined, due to the fact that the quarry is coded to stop at lava, or bedrock. A measure to prevent this issue is to fill the Quarry's excavation area with water. This will turn the lava into obsidian, which the quarry can mine. If the Quarry reaches bedrock, it will need to be relocated before it will mine again.
Quarries can be powered using MJ, BuildCraft's form of power, or EU, IndustrialCraft's form of power. When using MJ to power a Quarry, Engines must be used. When using EU to power a Quarry, an Energy Link is the best option. When using an energy link whilst early in the game a geothermal generator next to the energy link is a good idea. It is quite cheap to build and is easily fueled by lava cells wich can be easily obtained using tin to make empty cells then filling them with lava. Another good way is if you got a Peatfarm you could use a Peat Fired Engine as in that engine 1 peat lasts a while.
The Quarry, like all other BuildCraft machine's, has an internal energy storage in which it stores MJ until it can perform an operation. Because of this, the Quarry can be powered by any BC compatible engine. For the Quarry to operate at maximum mining speed, it needs 9 MJ/t, which is just under 2 combustion engines running on fuel, outputting 5 MJ/t each, or 9 steam engines, outputting 1 MJ/t each.
As the Quarry has only 4 sides free to attach engines to, one way to power a Quarry is to place 4 Sterling Engines on 4 of the sides. To run the quarry at full speed with Sterling Engines, Conductive Pipes must be used. Quarry powering level 2.Quarry powering level 3.===Using An Energy Link=== Energy Links can be used to power the Quarry using EU. The Quarry uses 22.5 EU/t to run at full speed, due to 2.5 EU being equivalent to 1 MJ. If not directly adjacent to the Quarry, the Energy Link will draw 80 EU/t. It is advised to place the Energy Link adjoining to the Quarry. The Geothermal Generator is an ideal choice for power, given the practically infinite quantity of lava available, and its energy output of 20 EU/t is near the maximum energy requirement of the Quarry. Generators burning some charcoal from a forestry tree farm give fully renewable power, but is obsolete to the ender tank nether pump exploit. ===Underground Operation=== Lighting is futile in a large underground Quarry.A Quarry can function at any level. Simply placing it against a shaft wall and powering it is all that is required to start the default 9x9 area. The blocks in the frame area will be destroyed. An underground quarry.It is possible to create a Landmark frame as per above ground. It is not necessary for there to be an empty path for all of the landmark beams. The beams can cross through all blocks.
You may also want to carve out the entire area inside the frame, as these are not mined, simply destroyed. To know exactly where, after setting your landmarks, place your quarry but do not power it. This will give you a black and yellow frame you can use as guidelines.
You may also do this above ground as you are not limited to only underground.
Produce of a quarryEdit
When making a quarry, it is generally recomended to feed the produce into a processing system,instead of storing it. Depending on how many materials and how much energy you have, you will either want to automatically feed the ores into macerators (IC2), crushers (Metallurgy), or pulverisers (TE) for double yeild, or use 2 to 3 levels of grinder from liquid metals, then melt and form into ingots. For the second option, setting up iron and gold, then tin and copper processing chains should be prioritised, as they will be the most widely used metals throughout the mods in the big dig pack.
The sorting is proberbly best done by usage of diamond transport pipes, with ores being sorted by the diamond pipes, and cobblestone being mostly recycled, partially stored with gravel, flint, dirt and marble and the remainder smelted into smoothstone. This would leave an output chest for ingots, gems, crystals and shards, and other for common (or building) materials.
Compared with Mining TurtlesEdit
Advantages of a quarryEdit
- A quarry can be powered by buildcraft or IndustrialCraft power, whilst a turtle needs coal or charcoal.
- Mining turtles need to be unloaded manually every few layers, whereas quarries do not.
- Quarries can lead directly into a filter/processing system
- Every time a mining turtle's inventory is full, it returns to the surface and takes a long time to decend again wheras quarries have no inventory
- A quarry remains stationary, allowing for easy access wheras a mining turtle decends into the hole it is digging
Advantages of a mining turtleEdit
- Mining turtles can be moved and/or replaced more easily
- Mining turtles have many other purposes.
- Mining turtles consume less power
- Mining turtles do not stop operation at lava
- The area that a mining turtle digs can be easily customised
- Mining turtles take up less space.
- Mining turtles don't require engines.
