Opis:
The paper presents the plight of KGHM Polska Miedź SA due to by the fall in copper prices on global stock markets. It has been noted that these prices apply to smelting copper. Meanwhile, the copper is in increasing quantities supplied to China in the form of concentrates. This causes a drop in prices of smelting copper which becomes less popular. Statistics since 2012 have recorded a permanent surplus of consumption over production of this metal. Therefore, the price of smelting copper will probably be at low level over the next years. It poses a threat for the future existence of the company. The exploitation of new deposits is conducted at a depth of below 1200 m. The rock temperature is about 55°C, which creates technical and financial problems. Mining work is carried out along the dip of the deposit at increasingly greater depths. In this direction, 10 km away, there is the “Wilków” natural gas field. It is proposed to undertake diversification of mining activities. Gold mining seems to be the prospective activity. Its economic concentrations occur in the mines of the KGHM, in the Lower Silesia region and abroad. Likewise, the company can achieve positive effects in investments related to the mining of diamonds.

Opis:
The paper presents a brief history of the origin and development of the “Konrad” copper mine located in the Grodziec Basin near Boles³awiec. Analysis of the decision on its close down in 1987 is provided. A two-page document stated that the former mine had been “permanently unprofitable”, without relying on the documents and facts in this case. Studies justifying this decision arose only several years later in a completely different economic situation. The mine sinking process was described. It encountered unforeseen problems with the simultaneous close down of a prosperous source of drinking water for the nearby villages. Currently, many professional communities and local governments put foreward proposals for the re-running operation on the deposit. The direct cause of this type of applications is the former foreign failure of the mine’s owner, which previously was Kombinat Górniczo- Hutniczy Miedzi in Lubin and currently KGHM Polska Miedź SA. A justification for this kind of concept is that the copper content in domestic deposits is several times greater than in the deposits purchased in the US, Canada and Chile.

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.
