What is used when ore is too deep within earth to be surface mined?
When ore is too deep within the earth to be surface mined, underground mining methods are used. This involves creating tunnels and shafts to access the ore deposits beneath the surface. Various methods such as drift mining, shaft mining, and room and pillar mining can be utilized based on the specific geological conditions.
Is onyx open cut mined?
Yes, onyx is typically open cut mined using traditional mining methods where the stone is removed from the earth's surface with heavy machinery.
What are the most commonly mined minerals and how are they extracted from the earth?
The most commonly mined minerals include coal, iron ore, copper, gold, and silver. These minerals are extracted from the earth through various methods such as surface mining, underground mining, and solution mining. Surface mining involves removing the top layer of soil to access the mineral deposits, while underground mining involves digging tunnels to reach the minerals. Solution mining involves using chemical solutions to extract minerals from underground deposits.
How is Chert mined?
Chert is typically mined through open-pit methods, where the rock is extracted from the earth's surface using heavy machinery. Sometimes, underground mining techniques may be used to access chert deposits located at greater depths. Once extracted, chert is processed and then used for various applications such as construction, tool making, or as a decorative stone.
What are two of the ways coal is mined?
Coal is typically mined using two methods: surface mining and underground mining. Surface mining, which includes strip mining and mountaintop removal, involves removing the topsoil and rock layers to reach the coal seam. Underground mining involves digging shafts and tunnels to access coal seams deep underground.
Is iron mined using surface or subsurface mining?
Yes

Is sandstone mined?
Sandstone is typically quarried, not mined. Its natural deposits are found close to the surface and are extracted by cutting blocks or slabs from the quarry walls. The process is less intensive than traditional mining methods used for minerals like coal or iron ore.
Why should the moon be mined for helium?
Meteor's, With iron,And other space debris on surface. Could be mined.
How the copper is mined?
Copper is mined through open-pit or underground mining methods. In open-pit mining, large machinery and explosives are used to extract the ore from the earth's surface. In underground mining, tunnels are dug to access the copper ore, which is then extracted using various methods such as blasting or drilling.
