{{Connecting Rooms|rooms=[[Quarry Access]]</br>[[Save Station Mines A]]</br>[[Security Access A]]</br>[[Waste Disposal]]}}'''Main Quarry''' is a room located in the [[Phazon Mines]] region of [[Metroid Prime]]. It is a very large room with multiple sections. At the ground level, there is a forcefield that blocks access to [[Security Access A]] which requires Samus to scan two different scan posts in order to deactivate. Above the forcefield are two Mega Turrets that deal strong damage to Samus. There is also a [[Spider Ball]] track that leads to the connecting save station. Leading to the upper level is a bridge that takes the player across the room, where Samus will be greeted with a few Space Pirates along the way. Once on the top level of the room, Samus can energize the nearby scan point using the [[Wave Beam]] and proceed to scan the mechanism that controls the crane. The crane can be set to one of two positions: either in its default position, where Samus is intended to use the [[Grapple Beam]] in order to gain access to the room [[Waste Disposal]], or bashing alongside a weak point in the upper level of the building, where a missile expansion will be revealed. Once the crane is in this position, the player is intended to use Spider Ball in order to climb the crane and gain access to the item.

In the original NTSC 0-00 version of the game, the door leading to [[Waste Disposal]] is unlocked from the very beginning. This was changed in the 0-02 version of the game, where this door is now locked until the player obtains the main [[Power Bomb|Power Bombs]] in [[Central Dynamo]].

This room also contains a [[Secret World]].

==Quickly Getting to the Top Level==
If entering the room from [[Quarry Access]], there are a number of ways to quickly get to the top level of the room. This is used by speedrunners in certain routes in order to quickly get to Waste Disposal. Getting to this room cuts out a large amount of travel time in speedruns.

===BSJ Method===

==Waste Disposal Door Without Grapple Beam==
Normally, Samus is only intended to get to the Waste Disposal door using the Grapple Beam. However, using a simple [[Scan Dash]], it is possible to easily clear the distance required without Grapple.

===Crane Jump Method===
If doing a Scan Dash isn't viable (eg. if playing on 0-02) then another method that involves jumping on the crane is an option.

===Wii===
A similar method to the above can also be done on Wii.

==Save Station Without Spider Ball==
The height required to get to the save station isn't very high, and there are a number of methods that can be used to make it without Spider Ball. In fact, a good enough [[Double Bomb Jump]] can be enough to bypass the Spider Ball track on its own.

==Secret World==
The developers intentionally made it difficult to get to the top of the room by raising the invisible walls far above where Samus can go normally. However, there is a part of the room's collision that is at an acute angle, where Samus can get stuck on the walls. This allows for Samus to get to the top of the room and get out of bounds, as holding the correct control stick position allows Samus to slowly float to the top of the room's box. The downside to this SW is that it takes about 18 minutes to do, so unless a faster method is found someday, it will never be useful in any speedrunning context.
