Surface mining can be classified into two groups on the basis of the method of extraction; mechanical extraction, or aqueous extraction.
What are the 4 main mining methods used in the gold rush? The majority of people that joined the gold rush were placer miners. Meaning they would dig up the soils that had been deposited along stream beds and use hand methods to sepa … rate heavy particles (like gold) from the rest of the material they dug up.

Fortunately for the miners, gold has an unusual quality: it is heavy, and thus all earlyday mining processes take advantage of this property. Another popular tool was the rocker or cradle, and indeed, this tool did vaguely resemble a child's cradle.
However, due to the uniqueness of each ore body, several variations of these methods are used. Before going into the details of the different mining methods, it is important to understand the main factors that determine the use of a particular method. The main factors to consider are the following:

There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits.
Choosing a mining method. The technological factors include, at a minimum, the number of seams, the thickness and steepness of each seam, the nature and thickness of the strata overlying the seams, the quality of the coal seams, the surface topography, the surface features, and the transportation networks available.
