Surface mining. Strip mining is sensible when the ore body is near the surface. The practice includes some of the largest machines on earth, removing long strips of overlying soil and rock and then removing coal deposits. Openpit mining utilizes blasting and mineral removing, digger deeper into the earth causing a craterlike result.

It Could Contribute To An Increased Level Of Birth Defects. If we are able to weight the pros and cons of mountaintop removal for coal mining, then we can determine if this is a practice we should continue. There are definite costsavings advantages that can be seen, but this comes at the expense of local geological changes. Only the local population can determine if the benefits outweigh the risks.
