Well i dont know but its best to ask your scince teacher, They know all (:

coal and technology
Technology has significantly improved safety and efficiency in coal mining through advancements like automation, remote monitoring, and improved ventilation systems. Automated machinery reduces the risk of accidents by limiting human exposure to hazardous conditions. Additionally, real-time data analytics help optimize mining operations, predicting equipment failures and enhancing resource management. These innovations not only increase productivity but also minimize environmental impacts associated with coal extraction.
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!
Using coal to generate electricity. (APEX)
No, coal is not environmentally friendly. Gathering it requires mining with machinery and burning coal produces many pollutants. Eventually, coal will run out. Solar energy is a good alternative since it is free and will not run out.
It is very important to use clean coal technology. The pollutants from burning coal causes health problems as well as environmental problems. The clean coal technology cuts back on these pollutants and provides a cheap form of energy.

When you burn coal you are using it not altering it.
Damage to the lungs from coal dust. Entrapment or death from cave-ins.
Yes. Cars do for gas

-crushing the coal into small chunks and washing out the sulfur dioxide. -burn the coal, reducing the NOx. this is called 'staged combustion'. -using a 'fluidized bed boiler', realising the sulfur dioxide, then the limestone captures the sulfur and changes it into calcium sulfate. hope this helps...its just a rough draft of how clean coal tech can be done though.
Coal is extracted in two methods. One is by digging tunnels into the earth and following the vein of coal, removing it by rail cart. The other is strip mining where they remove the earth above the coal and dig down to it. This way usually involves the removal of entire mountain tops to get at the coal. Recently however they have started to replant the vegetation when they are done to reclaim the land back to a natural state.
