What are the major types of mining?

There are four main methods of mining: underground, surface, placer and in-situ. The type of mining method used depends on the kind of resource that is being targeted for extraction, the deposit's location below or on the Earth's surface and the capacity of each method to profitably extract the resource.

What are the different types of mining Class 8?

There are two main methods of mining, viz. open-cast mining and shaft mining. Open Cast Mining: When minerals are taken out by removing the surface layer, the process is called open-cast mining. Minerals which lie at shallow depths are extracted by this process.

What is mining Class 8?

Mining is the process of taking out minerals from rocks buried under the earth's surface. The process of mining includes two methods: (a) Open cast mining, (b) Shaft mining. Deep wells are bored to take minerals out and this process is called drilling.

Characteristics of underground mining are: It is done when the ore lies deep below the surface. Lifts, drills, haulage vehicles, ventilation system for safe and efficient movement of people and materials are required.

What is the underground mining?

Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline.
