What Is A Mine Shaft Headgear?

Introduction to Mine Shaft Headgear

Mine shaft headgear is a large steel framework that hoists and lowers workers, equipment and supplies into the depths of an underground mine. Located at the surface, this structure is essential for mining operations as it provides access to resources deep below ground level. It typically consists of a mast or tower with pulleys, cable winders, cages (for personnel) and skips (for materials). In South Africa, they are most commonly used in gold mines due to their high concentration of minerals located beneath the earth’s crust.

History Of Mine Shaft Headgear

The use of mine shaft headgears dates back centuries ago when miners had to rely on human labor and manual tools such as pickaxes and shovels to extract valuable metals from the earth’s crust. With technological advancements over time, these structures have become increasingly sophisticated in order to better transport personnel safely between levels within an underground mine.

Components Of A Mine Shaft Headgear

A typical mine shaft headgear consists of several components:

Mast – This vertical supporting structure stands tall aboveground with its height varying depending on how deep down into the earth one needs access too; some masts can reach up to 100m in height! The mast holds all other parts securely together while also providing stability throughout operation.

Pulley Wheels – These are usually two or three large wheels which are connected by cables so that they rotate together around an axle during operation; these help provide support for both personnel/material loading/unloading along with controlling speed when ascending/descending levels within a mine shaft.

Winder Drums – There will usually be two winder drums located next to each other at either end of the mast which work independently from one another allowing for greater control over lifting/lowering operations; one drum rotates clockwise while its partner works counterclockwise so that both sides remain balanced during motion.

Cages & Skips – Lastly comes cages (or sometimes referred as ‘baskets’) which transport people up-and-down levels within an underground mineshaft while skips carry materials instead including ore samples etcetera. Both types often come equipped with safety features such as brakes for emergency stops if needed whilst navigating through narrow passages or difficult terrain below ground level!

Maintenance Of A Mine Shaft Headgear

It is important for any mining company operating out of South Africa understands that regular maintenance plays an integral role in keeping their machinery running smoothly- especially those involved in constructing heads like these ones mentioned here today! Proper inspection should occur every six months where all components need checking thoroughly before being put back into service again – this includes but not limited too: bearings lubrication points; wire rope tensioning mechanisms; brake systems etcetera… Any problems identified should then be rectified immediately before continuing operations further otherwise there may be potential risks associated with using malfunctioned equipment down below inside dark narrow tunnels! Additionally having qualified professionals carrying out inspections helps ensure quality assurance standards maintained across sites nationwide thereby ensuring safe working environments everywhere else!
