    These deposits usually occur beneath barriers like a rock layer, forests, or oceans, which makes accessing them difficult. Depending on how these ores are extracted, mining methods can be categorized as ‘surface’ or ‘underground’ types. In surface mining, the rock barrier on top of the deposit is removed to access the ore.

    Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal, or oil sands.

    Since the beginning of civilization, people have used stone, ceramics and, later, metals found close to the Earth's surface. These were used to make early tools and weapons; for example, high quality flint found in northern France, southern England and Poland was used to create flint tools. Flint mines have been found in chalk areas where seams of the stone were followed underground by shafts and galleries. The mines at Grimes Graves and Krzemionkiare especially famous, and lik

  • 10 Different Types of Mining Operations and Mines PopOptiq
    Types of MiningThe Advantages of Coal and Mineral MiningOther Benefits of MiningGlossary of Mining TermsBlock caving is a general term and usually has to do with a mass-mining system that relies on gravity to extract the ore deposits. A thin horizontal layer at the mining level of the ore column is removed, then due to gravity, the ore caves. One broken ore is removed from the ore column’s mining level, while the ore above it continues to break and cave by gravity. The term “block caving” likely started in mines with See more on popoptiqAuthor: Popoptiq

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

    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. In comparison to other methods, underground mines impact less on the environment and are much more harmful to those working within them.
