DIFFERENCE BETWEEN OPEN CAST MINE & QUARRY

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."

Complete answer:
The difference between open cast mining and quarrying are as follows:-

Overcast removal, dumping, and backfilling in excavated areas are all part of opencast mining operations. In recent years, a significant increase in the rate of waste dump accumulation has resulted in greater height of the dump for minimal ground cover area, as well as increased the risk of dump failures. In addition, steeper open-pit slopes are more likely to fail. These failures result in the loss of precious human life as well as damage to mining equipment. Continuous monitoring of dump and pit slopes is required, as well as the provision of early warning prior to the occurrence of slope failure. For slope monitoring, various technologies have been developed.
Quarrying is the process of extracting rock, sand, gravel, and other minerals from the earth in order to use them to make building materials or other products. As a result, a quarry is any excavation on the earth's surface where minerals are harvested. Quarries are also known by other names around the world: 'surface mine', ‘pit’, 'open pit' or 'opencast mine'.
