摘要

Resolution Copper Mining is sinking a 6943 foot (2116 m) deep shaft to access and develop a new panel caving mine with approximately 1.6 billion known tons of porphyry copper resource. This mine will take several years to ramp up to its full production level of 132,300 tons per day (120,000 tonnes per day) and is scheduled to begin production in the early 2020s. Resolution's shaft sinking contractor Cementation USA is using state of the art sinking methods combined with a largely local labor force to complete this record breaking shaft. Resolution's No. 10 Shaft has finished diameter of 28 feet (8.5m) and as of October 2013 is at the 6625 foot (2020 m) level. Upon completion in early 2014, the No. 10 Shaft will be the deepest single lift shaft in the United States. The majority of the shaft was blasted with bulk emulsion delivered by a pressurized loading vessel and by non-electric initiation. In the late stages of the shaft sink, high temperature rock and water inflow conditions (up to 179℉, 82°C) were expected and encountered. These conditions required a managed approach to ensure safe blasting application of bulk emulsion, packaged trim product, and initiation systems. Blast design and excavation methods were modified to meet the challenging conditions presented.
