Explanation:

Meaning of mining:

Similarities between contract open and underground mining methods:

• Surface area in the contract opening and underground mining requires a wide surface area.
• In both the methods wastages are first removed and then the whole process is followed.

Thickness and gradients are first identified in the both methods.

Answer 2

Similarities between contract open and underground mining methods are:

• There are two main ways to mine: open space and underground.
• Mines have changed and become more visible since your first duplication.
• Technological advances have improved efficiency, created a safer work environment and reduced environmental impact.
• Both open and underground mines are used in modern mines.
• The open mine gets its name because that is exactly what this type of mine looks like, a huge open pit.
• This type of mining allows for the extraction of minerals not far below the surface.
• The process keeps the work from going too deep into the ground.
• This has many benefits.
• Underground mining is a method used to access precious metals and minerals in the soil by digging into the ground for extraction.
• This is in contrast to methods such as digging open pits, where layers of land are taken for deposits, or removal from the top of a mountain, where the top of the mountain is cut to insert a stone inside.
