Transition from open-pit to underground in the case of

Geological and economic modeling of an ore body and also optimization of the depth at which transition is made from open-pit to underground mining is an important part of the mining design process in large and massive deposits. In this paper, a geological block model of Chah-Gaz iron ore deposit located in Iran was first created based on iron ore cut-off grade.

Paper: Case study: open pit three-dimensional slope

Abstract: The challenges of representing geotechnical failure mechanisms in software is being gradually addressed as search algorithms and computing power advance, especially to deal with complex anisotropic rock masses in which failure mechanisms are commonly three-dimensional (3D). This paper presents a case study of an iron ore mine with highly anisotropic rock mass strength that has been

Opencast to underground iron ore mining method

2018-7-28  At the end of the open-pit mining process in large metal mines, the mining model must change from open-pit mining to underground mining, but the mutual interference between the two mining models leads to poor production safety conditions and difficulties in production convergence during the transition period. To solve these technical problems of poor production safety conditions and
