An opencast or openpit mine is used to extract valuable deposits close to the earth's surface. Here the fragmentation, loading, materials handling and production control require heavy equipment. To maximise extraction volume and minimise the space for infrastructure, slopes within these mines can be steep.
Key words: Open pit mining, bench height, multicriteria decision making. INTRODUCTION As a definition in open pit mining, bench height is the vertical distance between crest and toe of the bench (Fourie and Dohm, 1992). Determination of optimum bench height is a major concern in most open pit mines.

02/03/2016 · An Overview of the Open Pit Mining Process. Openpit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling.
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 earth.
