This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western mining operations. All costs listed are in 2012 US.

Change in production and productivity of US coal mines The higher productivity for open pit mining equipment also lowers costs.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine – a pit, and the ...

Openpit 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 openpit mining. The removal of this material is known as stripping.
Underground mining is the oldest method of mining coal. From the late 1970s to early 1980s open pit operations increased, achieving high quantities of production and lower production costs. However, today, with environmental considerations and the greater depth of coal seam deposits, underground mining is proving to be the more viable alternative.
Consultant Measured Group updated the Isaac Plains reserve in August 2018 with current estimates supporting over 10 years of openpit mining at planned mining rates of Mt/y of product coal. Total openpit reserves as at August 2018 were Mt (run of mine).

Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter, this paper proposes a system dynamic model (SDM) for drilling and blasting operations as an interactive system.
Reduced Production Raises Cash Costs There is an inverse relation between the level of production and the per ounce cash cost. Higher production helps reduce the fixed cost components. Lower production can result from: • Safety related production stoppages • Technical problems • Lower grades
Sep 11, 2005· Openpit strip mining is the technique that coal operators prefer for removing the sparsely vegetated surface (overburden in mining terminology) of northeastern Wyoming that covers the coal seams. One of the largest of these mines, Peabody Energy''s North Antelope Rochelle Complex, is located at the center of this astronaut photograph.
