The answer lies in the advantages and disadvantages of coal for our modern world. ... Many coal mines use an open-cast method, which causes local animal ...
Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
Advantages of Adit Mining. Easier access to minerals – Adit mining allows for simpler reach to minerals as it involves horizontal digging into a hill or mountain, thus reducing the need for deep vertical shafts.; Less disturbing to environment – It is less harmful to the environment because it doesn't involve large-scale excavation, meaning less soil and vegetation disruption.

Open-pit mining. Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently ...
Open-cut mining is a process of resource extraction where it is dug up from the surface. Also known as open-pit mining or open-cast mining, it is the most common form of extraction for minerals or coal in Australia. The technique of open-cut mining is used when the deposits are close enough to the surface to be readily extracted.
Open cast mining is a useful method of extracting ore near the surface.
