  • 10 Different Types of Mining Operations and Mines – Nayturr

    There are five basic types of surface mining, including openpit mining, strip mining, dredging, mountaintop removal, and high wall mining All of these methods remove the waste material or the overburden, which is above the desired resource Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasonsOct 08, 2019  More specifically, mining is used to extract nonrenewable resources like fossil fuels, minerals and even water There are four main methods of mining: underground, surface, placer and insitu 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 A Guide to the Four Main Methods of Miningmining mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on mining Underground mining Britannica
