What are three kinds of tunnels used in subsurface mining?
they are vertical tunnels, angle tunnels, and horizontal tunnels. THE END
Why is surface mining cheaper?
In surface mining we dont make any tunnels. Surface mining is less risks as underground mining. In surface mining we follows the several conditions which are provides saftey.
What is the problems with mining?
Lack of clean air and tunnels collapsing onto your head.
What is a mining long tom?
it is a long mining tool used to mine gold it is usually made out of gold.
Why is underground mining is more dangerous than open-cut mining?
Because of the risk of tunnels collapsing and pockets of natural gas exploding.
How does mining affect the miners?
Mineral mining can disrupt the environment in multiple ways. One very common way is the digging that often accompanies such mining, where either an open pit or a network of tunnels is used to access the minerals. In some cases the land and water is polluted by chemicals such as Mercury that are related to the mining process.
What is deep mining?
Deep mining of any kind is done in tunnels leading off a vertical shaft into the ground, as opposed to 'open pit' or 'strip' mining. Deep mining is principally done for copper.
How were lanterns used in the past from mining towns?
In mining towns, lanterns were used by miners to light their way underground since there was typically no natural light. The lanterns were either carried by hand or attached to their helmets, providing a portable source of light to enhance visibility in dark, cramped mining tunnels. These lanterns were often fueled by oil or candles and played a crucial role in maintaining safety and efficiency in the mining operations.
What are bad things that can happen to you while mining?
black lung disease, mining cave-ins, smothering, gases in tunnels causing lack of oxygen, getting cursed out by rednecks
What are the revenue generators for coal mining services?
The most significant revenue source in the coal mining services industry is strip mining, followed by stripping overburden, sinking mine shafts, driving mine tunnels and drilling and blasting
What is deep shaft mining?
Deep Shaft Mining is two tunnels going deep underground, on tunnel for the miners to come up and down and the other for the coal to be lifted up to the ground.
What replaced the placer mining?
Placer mining was largely replaced by hydraulic mining and hard rock mining methods. Hydraulic mining used high-pressure water jets to extract minerals, while hard rock mining involved digging tunnels and shafts to access mineral deposits underground. These methods were more efficient and able to extract minerals from deeper beneath the surface.
