DESIGN OF OPEN PIT PUSH-BACKS IN CHADORMALU IRON MINE

01/08/2010  In open pit mine planning, push back mining sequence is widely used for long-term production planning. These push backs are designed with haul road access and act as a guide during the yearly scheduling process. Therefore, pushback design plays a key role in defining annual cash flows to be generated from a mining operation.

MINE SAFETY TRAINING HANDBOOK - UA Western Mining

Mine safety training saves lives. In 1978, the year the Mine Safety and Health Admin-istration was established, 242 miners died in mining accidents. In 2012 the number of deaths had dropped to 36. Training the people who work in the mining industry – and retraining annually – helps reduce deaths, injuries and illnesses.

Appendix G Pit Stability - NTEPA

This will enable the optimal design and mining sequence to be developed before any activity takes place. 5 Underground Voids The NTEC claims that “Question marks remain over the stability of the proposed open cut in proximity to underground workings”. This is an incorrect statement. The behaviour of the pit slopes and floors around the underground mine have been modelled extensively. The ...

SLOPE STABILITY ANALYSIS FOR OPEN PITS 1

In open pit mining, it is accepted to trade off some failures for steeper bench face angles, without compromising safety, since it is more economical to deal with regular clean-ups . than to have higher stripping ratios. This is generally referred to as a “managed” approach to slope design. A design reliability of 80% is generally accepted in open pit design, which means allowing 20% of ...
