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.
