Why open cast mining is safer for the workers than deep mining?

Open cast mining is generally considered safer for workers than deep mining because it involves extracting minerals from the earth's surface, reducing the risks associated with confined spaces and high-pressure environments found in underground mines. In open cast operations, workers are less exposed to hazards such as tunnel collapses, gas leaks, and poor ventilation. Additionally, the larger, more accessible working area allows for better emergency response and evacuation procedures. Overall, the surface nature of open cast mining minimizes many of the dangers inherent to deep mining.
