For most gemstone mines, whether it is base rock type or sand mine type, Most of the output of gems is irregular and unpredictable, so it is difficult to make a reliable evaluation of possible recovery rates. Most mining beds are located in distant, not easy to approach, and combined with other various factors to make such minerals in large and highly mechanized methods that are not cost -effective. Therefore, small -scale mining is often selected. Use simple methods and equipment.
Mreasted and most easy -to -mining minerals are mostly distributed along the dry riverbed, sometimes 20m from the surface. For example, some gem gravels in Myanmar, Sri Lanka, and Brazil have been mining for centuries by manual methods, and gem gravels near the surface of 3 to 10M can be digged into open -air pits, mined buried gemstones, and transported soil to recover gems; The deep gem gravel usually beats a well first, and then digs some horizontal lanes from the bottom. Although the unskilled gravel layer is relatively easy, the unskilled gravel layer may be soaked in water and it is easy to collapse during excavation.
The gem and mines in the base rock or solid gravel layer can be mining with a pick and a drilller. If you expected more resources, large equipment can also be used. Collecting gem materials often depends on physical strength. Bente can explode with explosives, but this may cause cracks or rupture of gem -level materials, so you should pay attention to the explosives not to be seen near the visible veins or mineral sac. Rinse first after the gravel is collected, and then sorted according to size and density. Finally, picking gem -level materials from the concentrate.
In large -scale mining gem and mines, the above mining work has been replaced by systematic and highly mechanized means.
The gem ore from the rivers and unsteady gravel layers mainly use large -scale open -air mining. For example, first drilling to determine the scope and possible recovery rate of the mine, and then apply modern technology to strip the soil and stack it elsewhere. Collect gem gravel with large equipment, choose gem materials from the concentrate and classify, and fill the dug out soil back to restore the landform. Most mines are equipped with a sink for operation. The operator was washed with a sieve in the sink. The less dense substance was washed away by the flowing water.
For the gem and mine in the base rock type or solid -clan layer, the mining work has a high technical content. Generally, specific schemes are drawn. Generally, the combination of manpower and light power equipment is generally used to use some specific methods to use certain specific ones. Tools (air compression hammer and handmade tools) chase the crystalline ore veins. Under the supervision of reliable personnel, the adopted Pausan minerals were immediately loaded into the lock box, and the waste stone was transported from the large hand to the stacking site.
