Open cast mining is one of the methods of gemstones mining, where the overlying minerals or rocks are removed to reach the gemstonesbearing rocks. The gemstonesbearing rocks are then washed by jets of water under high pressure to obtain the gems. These are then sent to
Here are the Types of Underground Mining and Their Applications. The method to be used for underground mining depends on the concentration of ore, strength of the surrounding rock, and the various risks involved. ScienceStruck explains what these methods are,
Advancements in geophysical methods provide opportunities for applications in exploration and development of many types of gemstone deposits. Megascale regional techniques, such as teleseismic signals, regional electromagnetic, and long range controlled source seismology (reflection and refraction)
Types of Gemstones list in English: Lets have a glance of the different types of gemstones available in the market. 1. Alexandrite or June Birth Gemstone: This is also known as a magical gemstone as it changes its colours as per the time when it is seen through.
Terrace mining is the term used to describe a mining method where the gem bearing rocks are exposed by digging horizontal terraces in steplike, generally circular formations. Blasting or digging is done and the debris is then washed to obtain the gem gravels. Emerald mining in Columbia (Chivor Mine) is the best example of terrace mining.
Jewels of gemstone were invented before our era. But in those days, their mining of the ball was more spontaneous than planned. Mankind began to extract precious natural minerals recently, by the standards of history, of course.
Subsurface mining can be classified according to the type of shafts used, the method of extraction or the technique used to reach the deposit. Drift mining uses horizontal access tunnels, diagonally sloping access shafts are used by slope mining, and shaft mining uses vertical access shafts.
Large pans are filled with water in the areas that are identified by the miners for gems. The pans are shaken back and forth to capture gems in the pan. Opals, rubies, amethysts, garnets, jaspers, etc., are all obtained from rivers or lake beds using river digging methods.

The mining techniques adopted to extract gemstones invariably reflect the nature of the deposit: primary deposits (in hard rocks, worked underground or in open pits) and secondary deposits (found in sedimentary, softrock, placers). The mineralogy of a gem dictates the type of geological environment in which it can be found.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
