Why do miners use helmet with powerful lamp?

Miners use helmets with powerful lamps to ensure visibility in dark underground environments where natural light is absent. The bright lamps illuminate their work areas, helping to identify hazards, navigate tunnels, and operate equipment safely. Additionally, having hands-free lighting allows miners to perform tasks more efficiently while keeping their hands free for tools and equipment. Overall, the combination of helmets and lamps enhances safety and productivity in mining operations.
