Garnet mining techniques can be divided into two common excavation types: surface mining and underground mining. Surface mining is done by removing surface vegetation, dirt, and if necessary, layers of bedrock in order to reach buried ore deposits. Sub-surface mining consists of digging tunnels or shafts into the earth to reach buried ore
The Garnet Mine was closed at the time of data entry with no known plans to re-open. Past operations took place from 1887 to 1953. Production size when active was considered to be small. Mine operations consist of surface and underground workings. There is one known shaft. Subsurface depth reaches a maximum of 148 meters (485 feet).
The Company has 7,000 files that utilize Vulcan Sub-Surface 3-D geologic modeling software (“Vulcan”). All historic and current drill data has been inputted to facilitate future core-drilling programs and mine planning in anticipation of development and future production.
Mining Garnets. Miners extract garnets in a number of ways. In open pit mining, workers remove the soil from an area, and then chip the rock out of the ground by hand or with machinery. Miners then go into the shafts and cut the garnet out of the veins and carry them to the surface. You can also find garnets in placer mines, areas of low
Most garnet found near Earth's surface forms when a sedimentary rock with a high aluminum content, such as shale, is subjected to heat and pressure intense enough to produce schist or gneiss. Garnet is also found in the rocks of contact metamorphism, subsurface magma chambers, lava flows, deep-source volcanic eruptions, and the soils and
Moreover, even after exhausting, the mines are not left barren. A 2m to 4m thick soil layer is placed over the filled and closed mine pits. So grass and trees can always be grown on that surface and the area gets its natural look back. This precious bluish aquamarine gemstone is mined incorporating a harmless and environmental friendly simple

Subsequently, the largest garnet mine opened there in 1983 and it is currently the largest source of industrial garnet in Australia, and arguably the largest garnet producer in the world. The garnets at this deposit were transported to the site by streams and rivers from a nearby area of very old (Archaean) garnet-rich metamorphic rocks.
Additional sub-surface mining methods include hard ro ck mining, which is mining of hard rock (igneous, metamorphic or sedi mentary) materials, bore hole mining, drift a nd fill .

Mining Operations. Data obtained from the Mine Safety and Health Administration (MSHA) indicated a total of 925 underground (6.2%) and 13,982 surface (93.8%) mining operations. Employees. A total of 59,922 employees, or 62,565 full-time equivalent (FTE) employees, were reported to MSHA as working at underground mining locations in 2008. This is

SURFACE MINING People use surface mining to remove ores that are near Earth’s surface. Three types of surface mines include open pits, surface coal mines, and quarries. Open-pit mining is used to remove large, near-surface deposits of gold and copper. Explosives break up the rock layers above the ore. Then, trucks haul the ore from

And in turn garnet can scratch softer gems, such as opals or pearls. Most garnets are not treated. Rarely, however, some garnets might be fracture filled, whereby treaters try to improve the apparent clarity of the gem by filling surface-reaching breaks with a glass-like substance. Such treated stones require special care.

Software, and hardware, is readily available now to increase the accuracy and speed of surveying, surface and subsurface mine design, and cost model application for feasibility studies. Camm's (1991) report on mining cost models so innovatively employed by Brower (1999) are now largely outdated (Thomas Camm, 2007, oral communication).
