Underground mining has lower rates of fatal and nonfatal injuries than surface mining.
Explanation:
Mining is an activity that consists of the processes of research, exploration, extraction and processing of ores. Although it is undeniably necessary for a society's socioeconomic development, it is still an activity that poses risks to the environment. Surface mining consists of extracting ore from deposits that are at lower depths, exploring it until it is exhausted. On the other hand, underground mining consists of extracting ore from deposits that are found at greater depths, exploring it for probes and topographic services.
Underground mining is more dangerous, because it has lower rates of fatal and nonfatal injuries than surface mining.
