Mining
Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

What are some diseases for coal mining?
The two most common are Black Lung Disease, from inhaling coal dust, and Silicosis, from inhaling dust from silica rock (sandstone).
Why do coal miners have helmets?
Rocks fall onto your head, and in low seam coal, you hit your head on the roof (last mine I was in was only 48" high) It also gives you a good place to attach your miner's lamp, so you can see what you are doing.
Miners used canaries in cages to detect hazardous atmospheres in the mines because canaries are more sensitive to mining gasses than people are. If the canary collapsed, that meant that there were poisonous gasses in the tunnel, and the miners would evacuate until the mine had been ventilated and was safe again.
What are two ways in which supplies of metal ores can be conserved for the future?
recycle and continue to use
Where diamonds are getting exhausted?
Whenever a natural resource appears to be 'exhausted', excavation ceases. However, in future times, technology can improve or the prices of the natural resource increase so that mining is profitable again.
Who made the greatest profits from the mining in the west?
People that sold things TO the miners- like food, equipment, entertainment.
What can cause a mine to cave in or explode?
It can happen if you drill into some gas or if you are using dynamite it ca sometimes go off when you do not want it to.

What are three kinds of tunnels used in subsurface mining?
they are vertical tunnels, angle tunnels, and horizontal tunnels. THE END
What is the process of refining minerals?
The process of refining minerals involves extracting the desired mineral from ore through physical and chemical methods. This may include crushing and grinding the ore, separating the mineral from the waste material through processes like flotation or leaching, and then smelting or refining the mineral to obtain a purer form. This refined mineral can then be used for various industrial applications.

Where do you get the re factor for explosives?
The RE factor (relative effectiveness) compares a given explosive's energy to TNT, with TNT being assigned a value of 1.0. Composition C4 is about 1.4- pound for pound, it has 40% more energy than TNT. The RE rating of a product would be listed in the manufacturer's information sheet, or taken from a data table for military explosives.

What are the macro processes of supply chain management?
§Supplier Management Process would include the goal of ensuring supplies at the best cost and terms, depending on whether it is a tactical purchase, a strategic buy, a negotiated purchase, or an engineered item.
§Internal Supply Chain Process includes a number of activities with respect to receiving, conversion and dispatch of finished goods.
§Channel Management: It is important to note linkages in distribution with multi-tier arrangements, depending upon the type of products moved.
§Customer Relationship Management: The focal organization orients itself to synchronize its role agents and processes to serve its customers. Customer delight happens only if the product meets the customers' satisfaction in terms of time, quantity, responsiveness and cost.
What can you do to minimize the effects of quarrying?
To minimize the effects of quarrying, you can use techniques such as reclamation of the land after quarrying is complete, reducing the environmental impact by controlling dust and noise pollution, implementing sustainable quarrying practices like reducing water usage and recycling materials, and conducting thorough environmental assessments before starting a quarrying project.
Is Data mining is the process of searching huge amounts of data with the hope of finding a pattern?
true
How many types of mines are there in the world?
There are various types of mines in the world, including open-pit mines, underground mines, placer mines, and drift mines. Each type of mine is designed for different geological conditions and extraction methods.
Why is open mining cheaper than deep mining?
it is cheaper because for deep mining ,the more deeper the minerals lies, the more difficult it is to discover and the more expensive to mine
