What is open stoping underground mining?
Open stoping is a mining method where ore is removed from an open excavation or stope. This method is commonly used for steeply-dipping or irregularly shaped ore bodies. It involves drilling and blasting to break up the ore, which is then removed using mining equipment.
What mining method is used to extract ore from beneath the earths surface?
The most common mining method used to extract ore from beneath the earth's surface is underground mining. This method involves creating tunnels and shafts to access the ore body underground, where miners extract the ore using various techniques. Underground mining can be more expensive and dangerous than surface mining but is necessary for accessing deep deposits of valuable minerals.
What mining method water power to separate gold from dirt?
The mining method that uses water power to separate gold from dirt is called placer mining. In placer mining, water is used to wash away the lighter materials, leaving behind the heavier gold particles. This method is commonly used in riverbeds, streams, and beach deposits where gold is found.
What is a mining method in which overlying rock material is stripped away to reveal mineral deposits is?
Surface mining is a method in which overlying rock material is stripped away to reveal mineral deposits. This type of mining is used when the mineral deposits are close to the surface, making it easier and more cost-effective to extract them. Examples of surface mining include open-pit mining and strip mining.
Does zinc have a partially filled 'd' sublevel?
Yes, zinc is a transition metal with a partially filled 'd' sublevel. Its electron configuration is [Ar] 3d10 4s2, meaning it has completely filled the 3d sublevel with 10 electrons and has 2 electrons in the 4s sublevel.
What is open stoping underground mining?
Open stoping is a mining method where ore is removed from an open excavation or stope. This method is commonly used for steeply-dipping or irregularly shaped ore bodies. It involves drilling and blasting to break up the ore, which is then removed using mining equipment.
What is a method for uranium mining?
Uranium mining can be either by open pit mining or by underground mining.
What are examples of unsupported mining methods?
One example of an unsupported mining method is Room-and-Pillar mining. This method involves timber beam supports to hold up the cave in which the mining is taking place. Another example involves using the mineral, such as coal, to hold up the walls. Pillars of the mineral are left in the mine as supports. This method allows for less of the mineral to be collected, because it is being used for the actual support of the mine. Correction Simply put, unsupported mining refers to the use of the grounds natural rock strength and the principals of ground control techniques to extract ore (with some waste) from the ground. There are two types of mining, surface and underground. The term support generally refers to the application of timbers, concrete, shotcrete, rock bolts, rock cables, screens, etc and a combination of these. Unsupported mining on surface is carried out successfully by designing pits with slopes that are at such an angle that the walls will not collapse during the extraction process. The ideal slopes have safety factors that are greater than 1.0. The ideal open pit mine would be one that would stand in place until all the economic material was removed, after which failing or slumping. Unsupported mining under the ground (u/g) is carried out successfully by designing openings either drifts, cross cuts, stopes, raises and other that are of the size and shape that they do not fail or "cave". Generally hard, competent rock that is not highly fractured, faulted, or jointed will lend itself to unsupported mining techniques u/g. Rocks that can be mined with the use of ground controlling tools or devices can generally be mined by a few different methods, room and pillar, longwall stoping, sublevel stoping, and block caving.
Is uranium more commonly mined world wide using the In Situ Leaching method or the conventional mining method?
In Situ Leaching method is more commonly used worldwide for uranium mining compared to conventional mining. This method is more cost-effective and environmentally friendly as it does not require as much ground disturbance as conventional mining methods.
What mining techniques are used today to mine sulfur?
Modern mining method..
How many orbital in g sub level?
There are 9 orbitals in a g sublevel. (there is 1 in an s sublevel, 3 in a p sublevel, 5 in a d sublevel, 7 in an f sublevel, 9 in a g sublevel, 11 in an h sublevel, etc.)
What is the difference between the method of oil mining and the method of rice cultivation?
Oil mining is done by mechanics while rice cultivation is manual.
Mining methods for detrital and residual clay?
Strip mining is the most common method.
The method of extracting minerals that involves digging beneath the surface is referred to as What mining?
This would be underground mining.

What completes the 4s sublevel?
The 4s sublevel is completed when it contains a total of two electrons. In the context of electron configuration, this sublevel is filled before the 3d sublevel, according to the Aufbau principle. Thus, the 4s sublevel is filled before the 3d sublevel begins to receive electrons.
