Abstract
In contemporary mining industry is very difficult to achieve production targets and profit without investing effort in detailed excavation planning. It is especially true for deposits with complex geological structure and production technology, as is the case for many coal mines in Serbia. The majority of coal production is used for generation of electricity in power plant. This fact is the main reason why production objectives of coal mine and power plant are strongly connected. Due to the fluctuation of the coal quality, operational mine planning (as a part of coal homogenization process), is of critical importance for managing successful coal quality control and meeting criteria of power plant. This paper investigates advantage of proper operational planning on coal quality control process and overall production performance. For better understanding case study is conducted on open pit Tamnava West field. Successful operational mine planning is almost impossible without use of modern software packages. For that reason in presented case study operational mine planning is done with Minex software.
Highlights
Modern mining is characterized by continuous worsening of production conditions
Tamnava West is a part of Kolubara coal basin, and it operates under governance of Electric Power Industry of Serbia (EPS)
The coal quality control management is of vital importance for successful production since coal mine and power plant objectives are strongly connected
Summary
Modern mining is characterized by continuous worsening of production conditions This is evident when considering the fact that the deposits on which exploitation is carried out are often, small in size, with poor quality and with complex structure and geometry, often in locations that have unfavorable infrastructure, or in regions with significant political instability. In Serbia, coal is the most important fuel in the generation of electricity, accounting for 65% of the power production 2. This fact is the main reason why production objectives of coal mine and power plant are strongly connected. For the management of the coal homogenization process at the mining block level is especially important to have enough of in situ data, and to conduct quality operational planning. Due to the complex nature of coal operational planning, usage of specialized commercial software is necessity
