Market risk in the hard coal mining industry in Poland in the context of the mining production planning

摘要

The hard coal mining industry is of strategic importance in Poland, due to the dominant share of hard coal in the energy balance and a significant role in the industrialization of the country, particularly in Upper Silesia. In recent years, the industry has experienced a deep crisis threatening its further existence, therefore the main aim of this article is to analyze and assess the market risk associated with the mining production in Poland in 2011-2016. Statistical measurements of volatility and the Pearson correlation coefficient were used in the research. The research results indicate that the level of production is not adjusted to the changing market demand and the high level of risk characterized by high price volatility and sale volume.
