Volatile commodity prices and industry market valuations are forcing mine operators to cut costs, limit capital expenditures, and boost productivity. The size and speed of profitability improvements are hard to predict and vary significantly by commodity, region, and specific mine. MineLens analyzes labor, cost, and equipmentproductivity data; benchmarks that data against a global set of ...
competitive cost basis. Australian metallurgical coal holds a very strong position in the seaborne market. This is driven by several factors, including the higher quality of Australian metallurgical coal (particularly from the Bowen Basin, which is generally considered the best metallurgical coal in the world), proximity to key Asian markets, enduser mine equity agreements, and stability in ...

mining equipment, mine planning, mine surveying, mineral processing and information technology. While advances in computing and mining software have increased the accuracy of calculations the multidiscipline variables remain difficult to quantify and are frequently not understood. Typically many assumptions are poorly documented. This paper presents observations of past and present estimation ...
ground mines recover only30 to 50 percent of the minable resource, although, averaged over all underground mines in the United States, the recovery ratio is63 percent.

• Mining equipment in Australia runs at lower annual outputs than most of its global peers. Australia is not best in class for output from any egory of equipment and is below the annual output of North America across all classes of equipment. • There is an inherent conflict between a productivity plan based on increased volumes and one based on cost reduction. Those mines with well ...
