  • Advantages and disadvantages of open pit mining

    Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or delicate, so that underground mining is not possible Labor costs are lower, both in excavation and transportation, and allow the use of large machinery The open pit design and scheduling problem is a largescale optimization problem that has attracted considerable attention during the last 40 years The development of the "knowhow" to improve economics of open pit mining projects through the use of mathematical optimization techniques goes back to early 1960's[PDF] Pit OptimizationStrategies for Improving Economics of Mining Jan 11, 2022  The mining industry welcomed the lifting of the ban, taking the position that the practice can be made environmentally sustainable “The mining method is dependent on the location and configuration of the ore body Openpit mining is employed for shallow or nearsurface mineral deposits, where underground operations are impracticalMore environmental disasters than economic benefits from open pit mining
