Answer 1

Answer:

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.

Explanation:

1. Surface Mining

Utilising the mammoth strength of Bucket-Wheel Excavators, moving up to 12,000 cubic meters of earth per hour, Surface mining is the process of seam mining coal and ore from the land. In this process, any unwanted earth or soil is stripped from the land and any ore or mineral that is sought after is found relatively close to the surface of the site.

2. Underground Mining

Underground or Sub-surface mining involves the digging of a network of shafts and tunnels into the earth to reach and extract the deposit of ore or mineral beneath the earth.

3. In-Situ Mining

A rarely used process of mining material, In-Situ or solution mining is the process of pumping a solution into the ore body, which dissolves the ore and is then extracted by a second pump. This method is used most in mining uranium deposits, with the Beverey Uranium Mine in South Australia being the nations first operating In-Situ Uranium Mine.
