The DTH hammer operates through compressed air, which is pumped through a series of valves and chambers within the hammer. When the air pressure builds up, it drives a piston that strikes the drill bit, creating a powerful force that breaks the material. This process continues in rapid succession, allowing the drill bit to penetrate the ground efficiently. The design of the DTH hammer allows for a larger drop height of the piston than traditional rotary drills, resulting in higher impact energy and better drilling performance.

Contrast this with Bajo el Pozo, which translates to Under the Well. This imagery conjures the feeling of being trapped, both physically and emotionally. The well is a deep, dark place that can symbolize despair, hopelessness, and introspection. A character under the well might find themselves grappling with their inner demons, searching for significance in the depths of despair. This setting highlights the human experience of feeling isolated and powerless, often leading to profound self-discovery and eventual liberation.
