202063· Open-pit mining is a surface-mining operation, in which rocks or minerals are extracted from the Earth by creating an open hole, or pit, in the Earth’s surface. These pits are generally 1km deep beneath the Earth’s surface, and are used to exploit low-grade ore bodies. This type of mining is used only when the minerals to be extracted are near the land surface, …

In fixed IPCC systems, the crusher stations are away from the actual mining face, often placed on or near the pit rim, leaving the trucks complete flexibility inside the pit. Semi-mobile and fixed IPCC systems could be easily retro-fitted into existing open pit operations without major redesign or rescheduling of the pit.
