This list of mines in India is subsidiary to the list of mines article and lists working, and future mines in the country and is organised by the primary mineral output. For practical purposes stone, marble and other quarries may be included in this list. In India, the underground mine
appropriate mining method is selected based on technical, economic, and environmentally accountable considerations. The first step in selecting the most appropriate mining method is to compare the economic efficiency of extraction of the deposit by surface and underground mining methods . This section reviews surface mining methods and
Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in

Security is a prime concern in any mine, whether gold mining or coal mining. A laser scanner can identify and record any cracks and fissures, compare these data to previous scans, and identify any areas of concern. This is an enormous contribution to mine safety and a safe work environment.
Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate.
The technical feasibility of hydraulic mining is well established, but equipment and systems that can operate in more diverse conditions will have to be developed. Like the mining of thick coal seams, other mining methods also leave a relatively high percentage of the resource in the ground.

Various Types of Drilling Machines. In a lot of manufacturing processes, one of the most indispensable machining tools is the drilling machine. The drilling machine is commonly called a drill press and is responsible for drilling various sizes of holes in any surface area and to precise depths.
3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour including all fuel and other costs and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.
Vast areas of wildlife habitat, the most biologically diverse forest in North America, have been obliterated. Roughly 2000 miles of streams have been filled or severly degraded by mining waste, all in pursuit of coal. And coal is a lousy way to power a society. From mining to burning to disposing the combustion waste, it’s a dirty business.

The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well
