Apr 27, 2015 · Choosing between openpit mining and underground mining is a decision that every mining company makes, but it is not based on the miner's whim and predilection. Selection always depends on the geometry properties of the deposit, its position, loion, and type. Generally, startup explorers and miners begin with openpit mining because it is ...

Underground mining is an economically viable option for exploiting ore reserves deemed uneconomic after open pit mining. However, underground development can have adverse effects on the above existing open pit slope walls. As a goal of this paper, identifiion and assessment of potential slope instabilities prior to underground development is crucial for safe and sustainable mining.

Ground water constitutes a significant operational problem and potential hazard in openpit and underground mining. The pressure of ground water in geologic discontinuities adversely affects the safety of height and slope angles of openpit mines, justifying measures to reduce groundwater pressures in their vicinity. The principal hazard in underground mining and tunneling arises from .

1 day ago · Currently been working as an open pit mine geotechnical engineer for the past three years straight out of uni. Very keen to move into the underground mining environment as a geotechnical engineer. However, worried about the long term consequences if I make the switch now. Was wondering if anyone else in the industry had worked in both sides and ...
