specific energy consumption of opencast coal mines

specific energy consumption of opencast coal mines [] Overview scantech.au. approximately 21% and the specific energy is approximately 22 MJ/kg. The sulphur content is between 0.25% and 0.35%, which means that it is a very sought after coal. There has been wide and intensive underground mining of the Rotowaro coal seams. This now results in many problems with coal quality maintenance from

specific energy consumption of opencast coal mines

specific energy consumption of opencast coal mines water and energy assessment for dewatering in opencast mines pumps are used in mines for dewatering and consume about 18% of the total energy usage in an opencast coal mine. quantitative estimation of water removal rate in a mine is necessary for designing an effective dewatering system and to minimise energy consumption.

Coal mining - Wikipedia

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 is called a 'pit ...

Open-pit coal mining in the United Kingdom - Wikipedia

Open-pit coal mining in the United Kingdom is in decline. Output has fallen every year since 2010. In 2010, the United Kingdom was forecast to produce about ten million tonnes (9,800,000 long tons; 11,000,000 short tons) of coal a year from open-pit mines.Most came from Scotland, with the largest operator there being the Scottish Coal subsidiary of Scottish Resources Group.

12/12/2018  The methodology was applied in an open-cast coal mine. The evolutionary algorithm was used in the optimization of the fragmentation size and hole diameter. The results of the case study show that the total mining cost is reduced $26,641 for the bench which corresponds a 16.8% decrease for one mining bench. If the usage of this methodology is extended to the other blasting benches throughout ...

Specific Energy Consumption Calculation (SEC) -

Specific Energy Consumption (SEC) – The Iron Steel, Mining, Engineering, and Heavy Manufacturing Industries are the largest energy consuming sectors in the world, these businesses consume a lot of energy that results in an increase in inputs cost. The purpose of the study is to calculate overall monthly “Specific Energy Consumption or Total Energy Consumption” which can be done

Quantification of Opencast Potential Within the Waikato ...

Currently there are two opencast mines in operation, Township (nearing completion) and Awaroa 4 (under development), producing approximately 1.6 Mt of coal annually. The majority of Rotowaro coal goes by rail to the New Zealand Steel Glenbrook steel mill and to the Genesis Energy Huntly Power Station. The remainder supplies North Island industrial and domestic markets. At Rotowaro a coal ...

Energy Consumption in Mining Comminution

There is a dearth of information about energy consumption specific to individual mines. One study [6], which is a collaboration that compares seven mine mill/concentrator operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where the energy requirement is broken down into six components: crushing, grinding, processing, tailings ...

Blast-Casting Mechanism and Parameter Optimization of a ...

Specifically speaking, once the blast-casting technique is applied in opencast coal mines for overburden removal, 30–65% of the materials can be directly thrown into the mined-out area without any need for further handling (Figure 1); thus, it will reduce the stripping cost by more than 30% [1, 2]. As a matter of fact, blast-casting is the most economically effective method in opencast mining.
