mining operation problems
restoration of the Polish school of prospecting for deposits - Opis:
- Since 1989, KGHM Polish Copper SA has become increasingly open to the world market for raw materials. In 1992, the Asacro Company from the US is trying to take over the KGHM PM SA. This is prevented by a strike of miners and steelworkers of this company,lasting 32 days. Since then, no attempts have been made to take over the company. Foreign investors are effectively deterred by one of the world’s highest production costs of copper – 1.82 USD/lb Cu. The cost of production of one ton of Cu had been 5227 USD by 2015. One of the reasons is an inefficient mode of mining. The start of mining from the uppermost part of the deposit means that some parts of the deposit cannot be, because it creates a threat to the sections operatingat lower levels. Similarly, mining works conducting from the wells to the boundaries of the deposit causesthe necessity to move to new areas of exploitation across already exploited parts of the deposit. It is proposed to eliminate these difficulties by directing the mining extraction process using an electronic control system that allows obtaining immediately the desired changes. The example of the Robert Friedman’s school of prospecting for new copper ore deposits, it is recommended to restoret he Polish school of prospecting for deposits, this time on a global scale for the needs of the KGHM Polish Copper SA and the Polish mining industry.
