Advantages & Disadvantages of Steel Construction
Advantages of Steel Construction. 1. Reliability. Steel structures are very reliable. The reasons for this reliability include consistency and uniformity in properties, better quality control because of factory manufacture, large elasticity, and ductility. If different specimens of some type of steel are tested in the laboratory for yieldDisadvantages. High Cost: Steel is usually more expensive than other building materials due to its strength and durability, and the production process requires a lot of energy and raw materials. Corrosion: Steel is vulnerable to rust and corrosion, especially when exposed to air or ground moisture.

Shaft construction QueensMineDesignWiki
Numerous advantages to a circular design are also seen in the construction of the development opening. Most mechanized equipment used in shaft sinking is more suited to a round shape rather than a rectangular because all points on the periphery are along the same radius for the axis of the shaft due to the symmetrical work area.Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners.
