首页 >> open pit coal production cost component
The production scale of the largest open-pit coal mine was 35 million tons/year, and over 20 large-scale open-pit coal mines' production was over 10 million tons/year. The total capacity of China's surface coal mines is about 950 million tons/year, accounting for about 25% of the total capacity of coal mines.

Phase Planning for Open Pit Coal Mines through Nested Pit Generation and Dynamic Programming This paper presents a phase planning method specially designed for coal deposits with nearly horizontal, bedded coal seams. The geology of this type of deposit is modeled into a column model, instead of a block model, to avoid coal-rock mixing in blocks.

The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and system-wide approach to minimize the total mining cost of bench …

the orebody "component" for which access has been provided can be identified; and, it is possible to accurately measure the costs associated with the stripping activity. Production phase stripping can yield two benefits. Firstly, it provides access to ore for extraction during the current period. Secondly, it provides access to future ore.

Open pit mining (also known as strip mining) is the process of extracting ore, minerals and/or fossil fuels that occurs on the surface of a particular mining site. When considering all the mining operations in the world, at least 40 percent of mining takes place at the surface reports Greenpeace International.

Coal production The Moatize mine's total coal production decreased to 5.87Mt (3.09Mt of metallurgical coal and 2.78Mt of thermal coal) in 2020, due to the impacts of the Covid-19 pandemic. The mine produced 4.03Mt of metallurgical coal and 4.73Mt of thermal coal in 2019, compared to 6.1Mt of metallurgical coal and 5.4Mt of thermal coal in 2018.

Increasing the coal price (or lowering the production costs) had reverse effects on the planning outcome, as expected. Setting the annual escalation rates of coal price and production costs to 2.0% and 1.5%, respectively, resulted in a 7% larger ultimate pit, the same number of phases, but larger phase-pits.

In an open-cast mining operation, the production cycle comprises drilling, blasting, loading, hauling and coal preparation subsystems. Significant cost savings can be achieved by minimizing the cost of these activities (Kozan and Liu 2017 ). However, optimizing a single subsystem does not mean that the whole system is optimized.
