In today’s technologically-advanced society, mining techniques are always improving. For example, using surface mining techniques, miners are now able to extract over 85 percent of minerals and 98 percent of metallic ores without digging a shaft or endangering the lives of workers. Newly-developed machines used for grinding and crushing can extract minerals from the earth with less energy than ever before.
Miners still use heavy machinery, such as explosives, trucks, drills and bulldozers, especially if they must dig deep into the earth. However, advances in technology have allowed miners to excavate with more accuracy and less harm to the surrounding environment. More efficient machinery can also be used to reduce energy consumption and improve the amount of minerals or metals gleaned from the shaft.
The history of mining is rich and complicated. Mining has led to great advancements for society, but the dangers of mining have also resulted in the deaths of many workers. As technology continues to advance, however, mining techniques become even more accurate and efficient. In the future, revolutionary technologies may eliminate the need for hands-on involvement from miners entirely.
