Answer 2

Answer:

A mine's Headgear transports miners and objects inside and outside of the mine.

Explanation:

All right,  the headgear of a mine is a mechanism constructed in a system o pulleys and gears that lifts and bears people and objects inside or outside of the mine. It is a rudimentary lift with a cage protected by gates that let the people and objects stay inside of the headgear. It also functions with a mechanism of only two buttons, one to pull up and one to loose down. Sometimes they even have a telephone or an emergency communication system in case of an accident.
