'''Mining''' is the process of fetching natural [[raw materials|raw material]] from below the [[Mars|Martian]] surface for further processing. The fetched raw materials are frozen [[water]], [[minerals]] and [[ore]].

==Technology==
Mining is an [[energy]] consuming job. Due to the thin [[atmosphere]] the [[digging machine]]s are supposed to work [[automation|automated]] or remote controlled.

==Surface Mining Methods==
===Strip Mining===
When resources are available close to the surface, a strip mine is the most efficient method of extraction. The layers of [[regolith]] covering the resource are taken away, and the exposed ore is mined. This method is also called open-pit mining.

==Subsurface Mining Methods==
When the natural resource lies far underground, it is far more efficient to dig tunnels to access the ore than to remove the overlaying rock and regolith. Since Mars has only about 38% as much gravity as Earth<ref> McGRAW-HILL ENCYCLOPEDIA OF Science & Technology, 8 th edition, vol. 10 (c) 1997 page 527 </ref> people should be able to extend mines to a depth about 2.6 times as deep as on earth without the tunnel collapsing from hydrostatic pressure. This should allow the search for valuable minerals to a depth of more than 5 miles. There are many subsurface mining methods, and they are often used in conjunction with each other.
===Drift Mines===
Drift mining consists of primarily horizontal tunnels. These are most often dug into a hillside.

===Slope Mining===
Slope mining uses diagonal tunnels to access ore.

===Shaft Mining===
Vertical shafts are used in shaft mining.

My first step was making a great big giant caneadlr and taping it to the wall above my iMac. Because I forget everything, and I can't keep track of time. Somehow since I started freelancing full time my productivity went down the drain, because I no longer have a tight time frame to make it work. Turns out I needed the structure and the pressure of juggling several jobs at once. I just procrastinate otherwise. So, caneadlr to write down everything in is my first step. Step number two writing a daily schedule. It's List Time!

===Longwall Mining===
Longwall mining begins with a long horizontal shaft. The roof is held up mechanically by moveable supports. One side of the shaft is mined along its entire length. As this mine progresses, the mechanical supports move foreward with the face. The old area of the mine is left unsupported, and allowed to collapse under its own weight, often leading to surface subsidence.

==Emerging galleries==
The [[artificial cave]]s are a nice side effect. They can be used to expand the [[settlement]] with storage rooms, [[house|living rooms]], underground [[greenhouse]]s, gas container for [[energy storage]] or storage of [[:category:chemistry|chemicals]].
