Improving Double Bench Face Performance At The Ekati

Double benching has been utilized as an excavation technique in open pit mines for many years. This process involves drilling, blasting, and excavating the material for the design bench height. A second bench is then excavated without the creation of a catch bench, i.e. only minimal offset from the first bench face is allowed when.

Mitchell pit in the KSM project will have an extremely high engineered pit wall and as such, controlled drilling and blasting must be needed to allow safe operation of the pit. 2. Drilling Production drilling will be done with electric drills with a 15m bench height. Similar sites and a study done by Orica refer to Appendix .

Openpit Mining Methods

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.

Economic Assessment And Mine Production

development will be addressed, including, but not limited to the open-pit design, production rate, tailing facility construction, haul road construction, blasting design, and material handling equipment selection. The present study is intended to develop the economic assessment and mine production.
