Why is open pit safer then shaft mine?
it cant collapse in the way shft mines can. As Shaft mines are underground it makes it alot more easier for it to collapse on everyone and they will all die so therefore open pits are much much safer than shaft mins. Thanks
Is coal and oil being formed faster than humans are using it?
Really and truly, coal and oil aren't being created fast enough for human use. Coal is most likely not to be used that often; since not everyone is burning coal, we have plenty of it. Oil is a different story. Since we use oil, sometimes in our daily lives, it has to be produced more often the coal, because me use it so much!
Is A Coal Power Station Better Than A Nuclear Power Station?
yes a coal is nature nuclear uses lots of power Process for production of power from coal is very inefficient , More over it produces lot of carbon dioxide in to atmosphere (harmful green house gas). While Process for production of power from Nuclear plant is very good when compared with coal power. But initial and maintenance cost is very high. Unit cost for coal power is more economical than nuclear power. So economically coal power station is better. But on the basis of efficiency Nuclear power stations are good. When the deaths caused by the two types of mining are considered, coal fired systems have a much higher overall death rate. But the coal mining industry is improving this.
What are clean coal technologies designed to do?
Clean coal technologies are designed to stop the emissions of Carbon Dioxide into the atmosphere. CO2 is captured and stored safely away for millions of years. Governments are sinking a lot of money into this technology, as if it can be made to work, they will be able to keep on burning coal without contributing to global warming. Sadly, they have no successful examples that are economically or commercially viable. Underground storage is unreliable. Methods of removing and compressing the millions of tonnes of carbon dioxide use as much energy as is obtained from burning the coal, leaving nothing left to generate electricity.
How much weight can an excavator lift?
Depending on the size of the excavator , 1 to 3 tons, larger excavators used in mines and road building applications can lift 5-20 tons . Mini excavators can lift smaller than a ton.
How much did children in coal mines get paid?

Is there much water in coal mines?
Will depend on the mine, but in general, underground coal mines may be very wet. One of the first uses of early steam engines was operating mine pumps to control water levels.
Why is it hard to get coal for fuel?
Coal isn't all that difficult to get; there are hundreds of coal mines scattered over much of the North America, and central Europe has a lot of a soft "brown coal" called lignite. There's also plenty of coal in China and central Asia. Much of British industry depended on coal mining, and coal-fired steam engines powering pumps to drain the deep coal mines bootstrapped most of the Industrial Revolution. If you want some coal, it can be delivered in dumptruck loads.
How much does a electrician make in the mines?

How deep did the coal miners have to dig to get the coal?
Depths of coal seams vary from place to place. The first coal mine in the US was in Midlothian VA, near Richmond. Coal was present on the surface- just pick it up. Later mines in that area were about 360 ft deep. Other mines are deeper- but much coal is still mined from the surface in high wall or long wall mining.
Why do coal mines explode?
Coal dust in the air is an explosive mixture, because the mixture of coal and air can burn much more rapidly than solid pieces of coal can (flour in the air is also explosive, or sawdust - any flammable substance in the form of dust becomes explosive if it is mixed into the air). The process of mining coal is messy, and creates a lot of dust. And any spark can set it off. No smoking in the coal mines!
How much does it cost to make electricity from coal?
That very much depends on the cost of the coal. Question has no answer

How were the sheltland pony used in the 30s?
Shetland ponies were used in the coal mines to pull the coal carts out of the mine shafts. There small size and pulling power made the miner's work much easier.
What are the advantages and disadvantages of coal mining?
Coal mining has many very bad cons and drawbacks. For one, it is highly dangerous. Coal mines have been known to collapse in on workers, trapping or killing them. The dust and dirt and materials in the mines and air around the mines can be polluting and can be very harmful when breathed in or on the skin, especially for longer periods of time. Coal is a finite resource. It take millions of years to replenish itself. With the limited amounts constantly being mined and used for energy, the resources of coal around the world are depleting. If mining continues, eventually there will be pretty much no more coal left. The effects of burning and using the mined coal for energy also cause pollution and are bad for the environment.
Why do people take so much coal?
