What is the difference between open cast mining and quarrying Login Study Materials NCERT Solutions NCERT Solutions For Class 12 Open cast mining The process of extracting minerals from the surface layer is open cast mining Quarrying Quarrying is the extraction of stones from rock surfaces
·Open pit mining is usually done for those minerals which are lying close to the earth s Quarries are mines that are used to mine a deposit that lies at the earth s surface less difficulty or like limestone gypsum are extracted like Underground mines are used when minerals are deep beneath the earth s surface a vertical opening in an
·Difference between Mine & Quarry This question was asked in Indian Bureau Of Mines Assistant Controller of Mines Exam Interview A quarry is the same thing as an open pit mine from which minerals are extracted The only significant distinction between the two is that quarries are open pit mines that generate building materials and dimension stone "
Open Pit MineAn open pit mine refers to a large excavation made in the ground for the purpose of extracting valuable minerals or other geological materials Here are the key characteristics of open pit mines Excavation Open pit mines involve the excavation of the earth s surface to access the desired minerals or materials This excavation is done using heavy machinery such
·Open pit mining plans include implementing operations throughout the entire life of the mine In addition to geometric and geotechnical constraints it is important to ensure an uninterrupted ore feed by optimizing production plan In order to achieve this and at the same time maximize the net present value the most well known method is Parametric Analysis Method
Hint A quarry is the same thing as an open pit mine from which minerals are extracted The only significant distinction between the two is that quarries are open pit mines that generate building materials and dimension stone " Complete answer The difference between open cast mining and quarrying are as follows
·These include strip mining open pit mining mountaintop removal dredging and highwall mining How deep do surface mines go Surface mining means the extraction of mineral deposits or coal reserves or stones of different kinds that are outcropping the earth s surface or located at shallow depth from it
·What is the difference between an open pit mine and an underground mine Open pit mining is a technique used to extract copper ore near the earth s surface Underground mining is used when the copper ore is not near the earth s surface Miners dig a shaft into the ore deposit vertically or a horizontal tunnel or adit in order to do this
·Open cut mining is a process of resource extraction where it is dug up from the surface Also known as open pit mining or open cast mining it is the most common form of extraction for minerals or coal in Australia The technique of open cut mining is used when the deposits are close enough to the surface to be readily extracted
·Open pit open cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow A Q u a r r y a place where sand stone etc is dug out of the ground

·1 The ore body is too deep to mine profitably by open pit 2 The grades or quality of the orebody are high enough to cover costs 3 Underground mining has a lower ground footprint than open pit mining The underground mining methods we use include room and pillar narrow vein stoping and large scale mechanised mining
Mining operations have many guises Surface mining involves uncovering resources by removing overburden This is done in several ways but for metal deposits open pit mining is most common The Bingham Canyon Mine Figure above near Salt Lake City is the world s deepest open pit It is km by km in area and is km deep
·Open pit mining can also be identified as open cast or open cut mining The practice operates above ground always at the surface extracting minerals and rocks from the surface Open pit mining presents fewer dangers in comparison to underground mining these surface mines do not need to tackle issues such as air loss and cave ins nor do
·Strip mining and subsurface mining Strip mining or surface mining is performed when surface soil and rock are stripped off to reach the mineral of concern When such operations are done surface water bodies lakes streams etc gets acidity Acid mine drainage occurs when water molecules infiltrates the spoil banks The water reacts with sulfide minerals to produce
Open Pit MineAn open pit mine is a large excavation where minerals are extracted from the surface of the earth The process involves the removal of overlying rock and soil to access the mineral deposit Large amounts of overburden need to be removed to reach the mineral depositEquipment such as excavators and haul trucks are used to extract the mineralsIt is cost
·2 Decline Shaft Systems 3 Open Cast Salient Features 1 Conventional mining can be done any reef dip 2 Mechanised mining typically never gets done when the reef dips more than 10° 3 Conventional mining can be done at mining widths upto 2 0 metres whereas Mechanised can be done above metres 4 Shaft systems the sequence is 1st
·Open pit mining is a technique used to extract copper ore near the earth s surface Open pit mining is the most widely used technique of mining copper today Miners dig a shaft into the ore deposit vertically or a horizontal tunnel or adit in order to do this Mining then follows the vein of ore and the underground mine develops
·The typical large open pit mining operation that has been in production for 10 years and more is operating under conditions that could not possibly have been foreseen by the orig inal planners of
·Shaft mining can be considerably more dangerous for workers Cave ins gas leaks and other health hazards create anxiety on the job Many workers prefer the safety of the surface to conduct their excavations In addition an open pit mine generally integrates large scale hydrology solutions to prevent acid mine drainage
A mine is a place where minerals and other valuable substances are extracted from the earth through underground tunnels or open pits On the other hand a quarry is a type of open pit mine from which rock sand or minerals are extracted
·Large stripping machines with excavating wheels used in surface coal mining are employed in other types of open pit mines Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century After that steam driven pumps could be used to remove water from the deep mines of the day
·What is the difference between open pit mining and strip mining What is the difference between open cast mining and shaft mining Class 8 Minerals can be extracted by mining drilling or quarrying Fig Minerals that lie at shallow depths are taken out by removing the surface layer; this is known as open cast mining
·The Southern African Institute of Mining and Metallurgy Platinum 2012 101 Rupprecht MINE DEVELOPMENT ACCESS TO DEPOSIT Rupprecht University of Johannesburg Abstract A deposit to be mined by underground methods can be accessed by a number of methods • Adit • Decline or ramp • Inclined shaft • Vertical shaft
