26/02/2018· Stockwork vein deposits occurs veins in heavily fractured rocks by mineral rich aqueous fluids. While the mineralization may be rich the veins are often thin and widely distributed, re-vein is thicker and more persistent it may be economical to mine a particular vein using underground mining techniques. This is particularly so in the value of the commodity produced is high such as for gold silver, molybdenum, bismuth or antimony. Such mining

Mining Underground mining Britannica

Mining 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 the

What is Underground Mining? (with pictures)

20/01/2021· Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ore inside. When people think of mining, they often visualize underground mining

Here are the Types of Underground Mining and Their

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. However, sometimes, such deposits occur too far below to access them from the surface. In such cases, they are extracted by leaving the overlying rock intact, and accessing the deposit directly from
