Open Pit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow The word is used to distinguish this type of mining from extractive methods that need tunneling into the earthpractice in open pit mines The application of sound geotechnical engineering practice is considered to be an integral component of Part 2 of the Mines Safety and Inspection Act 1994 (MSIA) It is emphasised that this guideline is not totally inclusive of all factors concerning the application of geotechnical engineering in open pit miningGEOTECHNICAL CONSIDERATIONS IN OPEN PIT MINES

Overburden management in open pits: options and limits

Over 90% of the mining activities in developed countries adopt open pit methods In large open pits, the orebody is usually found relatively close to the surface (thus ensuring overburden–to–ore ratios suitable for profitable mining operations) in subhorizontal or slightly inclined depositsMining, especially surface mining, has a significant impact on the upper part of the soil cover, including fauna and flora The article deals with the use of geodetic methods to observe the mining process and its possible impact on the environment The created model can be used to design the recovery and reclamation of openpit mines after their closure and mining terminationUtilization of Geodetic Methods Results in Small OpenPit
