In coal mining what is a good strip ratio? -
Coal mining is good because it is used to get a very important natural resource, coal. Coal is used in many things and without coal mining we could not do those things.
Coal mining is good because it is used to get a very important natural resource, coal. Coal is used in many things and without coal mining we could not do those things.
For instance: If the thickness waste rock (overburden) is 100m and the thickness of coal is 50m then stripping ratio would be 2:1. That means one m3 (cubic meter) of coal would need mining two m3
mUltiple-sewn strip-mining industry seems as favorable as Iltat predicted for the entire industry. A TYPICAL MULTIPLE-SEAM SURFACE COAL MINE Using a walking dragline and an electric sboveJ in tandem, Peabody Coal Company. at its Homeslead Mioe in Ohio County, Kentucky, has developed a method of recovering three seams. These seams are the Kentucky No. 9,
May 26, 2020 5:28 PM The coal ministry had recently asked NTPC to prepare separate mining plans for both the blocks, an official said. The stripping ratio of these blocks is also very high, more
Within the coal industry, this is known as the stripping ratio (or overburden ratio in Argles, 2005). Stripping ratios can be calculated either in tonnes or in thickness ratios (commonly used in coal operations). The maximum economic stripping ratio for surface mining has steadily increased over the years to around 20:1, helped by improvements
Open cut mining methods strip mining Large-scale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significan t developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and operating at higher stripping ratios (Westcott et al.,
Coal mining is good because it is used to get a very important natural resource, coal. Coal is used in many things and without coal mining we could not do those things.
Additionally, the stripping ratio can be a dynamic parameter in a mine, changing over the years, depending on the cut-off-grade strategy and the overall mine planning of the project.

Stripping ratio . The main factor in designing a n open pit mine, which largely determines the cost of mining, is the stripping ratio. Stripping is the removal of waste rock from above and around the orebody. Stripping ratio is defined as the tonnage of waste rock to be mined, divided by the tonnage of ore to be mined from the pit. Stripping ratio is influenced by the shape of the orebody and

09.05.2020· The stripping ratio method of calculating the profitability of the mining procedure is commonly used in the ore or coal mining process. In relation to its application in the mining of ore, the utility of the stripping ratio is the determination of the approximate ratio of waste material that must be moved in order to reach a certain ratio of ore.

Overall stripping ratio (SRo) is the progressive or cumulative ratio of benches in consideration. For instance the overall stripping ratio of two (2) benches will be the ratio of sum of waste to ore. This is purely a physical ratio of total waste to total ore. [Note: Equation 2 is expressed in tonnes (t), can also be expressed in volume (m3)]
In coal mining: Choosing a mining method calculated with the aid of stripping ratios, which represent the amount of waste material that must be removed to extract a given amount of coal. Stripping ratio s can also consider the selling price of coal, and a certain minimum profit can be added to the total cost of producing and

In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore. For example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock 1.6K views View 3 Upvoters
Stripping Ratio determines relative amounts of each to be moved If coal generates a $5/ton earning and overburden costs 45 cents per cubic yard to move what is the maximum economic stripping ratio $5.00/ 0.45 = just over 11 cubic yards per ton Called a Break Even Stripping Ratio
