Stripping Method Of Mining

Strip mining is the least efficient method of mining AND you wear out your tools on mostly cobblestone AND you are left with an enormous hole in the ground that just looks ugly If you are looking for diamonds you should branch mine at y=11 Then you can use a water bucket to turn the lava level into floors for your branch mine when you encounter them 1 Share Report Save level 2 · 3y

A strip mining technique wherein an active mining area is continuously moved across a mining ground Overburden is removed from a leading end of the active mining area and conveyed by a conveyor system located on a high wall of the mining area to a following end of that mining area The conveyed overburden is dumped adjacent the active mining area following end to form a spoil bank which is

Strip mining removal of soil and rock overburden above a layer or seam particularly coal followed by the removal of the exposed mineral The common strip mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type

The present invention relates to a combination of open cast strip mining and auger mining of thin seams of hydrocarbonaceous deposits In this mining method a first working pit is stripped to expose the deposit the hydrocarbonaceous material extracted and the exposed deposit seam face of at least one highwall is auger mined A second and successive working pits are opened parallel to but

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

The maximum allowable Stripping Ratio SR max defines break even stripping ratio BESR This represents the highest possible units of waste that can be handled If the SR exceeds the BESR then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in mining

Strip mining is done layers where the mining operations go slighter deeper with each pass Strip mining is a type of surface mining which involves the removal of a thin layer of material known as an overburden to access buried deposits of useful minerals This type of mining is only effective in areas where mineral deposits are very close to the surface making it feasible to quickly and

Strip mining This process involves the method of extracting the mineral by removing soil and rock which are deposited on the and Lignite are the two principle minerals that are extracted through this method This kind of mining can be done when the mineral to be extracted almost near to the process is divided into area stripping and contour stripping This method of

Conventional mining The first fully mechanized underground mining method involving the insertion of explosives in a coal seam Stripping ratio The unit amount of overburden that must be removed to gain access to a similar unit amount of coal or mineral material Stump Any small pillar Subbituminous Coal of a rank intermediate between lignite and bituminous Subsidence

2021 12 04· 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

Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips The pits are parallel and adjacent to each other Strip mining is fundamentally different from contour or area mining on how the overburden is

2021 08 26· A stripping activity asset is depreciated or amortised on a systematic basis over the expected useful life of the identified component of the ore body that becomes more accessible as a result of the stripping activity The units of production method is used unless another method is more appropriate Application and transition

1 Mining Methods Traditional mining methods fall into two broad categories based on locale surface or underground 1 Surface mining includes i Mechanical excavation methods; such as Open pit and Strip mining ii Aqueous methods; such as placer and solution mining 2 Underground mining is usually classified in three categories of methods

Strip mining is the mining of a relatively flat deposit very close to the surface commonly used in coal or phosphate industries ANATOMY OF AN OIL SANDS DEPOSIT Oil sands deposit are normally located less than 50 meters below the surface A layer of topsoil containing trees shrubs vegetation and swampland normally covers the deposit An oil sands deposit consists of 4 distinct layers
