  • What are the different types of mining and how do they differ?

    As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesnt require tunnelling into the earth and is a simple method of mining that yields high production rates.

    When the mineral seam becomes exposed, it is drilled, fractured and the mineral recovered for processing. Open cut mining can be more effective than underground methods, generally recovering 90% of a mineral deposit, and accounts for about 65% of raw coal production in NSW. Open cut mining is also used for some gold and copper production in NSW.
