Mine shaft head gear
What is a mine shaft?
A mine shaft is a structure used to carry miners and minerals to/from the work level. A mine shaft has structural members that work in different ways. Mine shafts are made out of steel and iron to make them strong.
Members of the mine shaft
Members of the mine shaft have different characteristics. The members are as follows:Pulley-is used to pull the elevators that carry miners and minerals to/from the work level. In a mine shaft, two pulleys are required. Crank-it’s a pole used to keep a pulley in place whilst the pulley rotates. Rope-this kind of steel rope must be strong in order for it should be able to withstand heavy loads.
Kinds of bracing used in a mine shaft
In order for a mine shaft to remain rigid, the bracing must be cross bracing. This kind of bracing makes the mine shaft rigid.
How important are mine shaft
Mine shafts are important because they bring minerals to the surface which help build up the economy. They carry important minerals to the surface which help sustain the economy.
Where are mine shafts situated?
Mine shafts occur in places which are high in minerals, for example Gauteng and Kimberly. Sometimes they can be seen in television soapies such as Isidingo and Gold diggers.
How do we make the model?
We first make investigations that contain design brief, specifications and constraints. Then we do initial ideas and freehand sketches. Then we make designs that include First Angle Orthographic Projection and Isometric Drawing. It is only then we go to collect the materials and tools to make the model.
