Opis:: The aim of this work was to investigate the influence of anti-pyrogenic materials with use of Combustion By-Products (CBP) on the tendency of coal mining waste to self-ignite in laboratory conditions. The tested material sample was a mixture of coal waste with an addition of anti-pyrogenic material based on coal combustion by-products. The laboratory installation to test the properties of anti-pyrogenic materials is presented. The temperature of the tested sample as well as the concentration of carbon monoxide in exhaust gas were chosen as the parameters which determine the properties of anti-pyrogenic materials to reduce the self-heating process of coal waste. Laboratory tests of material samples were performed in a temperature range from 40°C to 500°C, at time interval of 350 s.

Opis:: The paper contains reference literature analysis concerning mercury content in Polish bituminous coal and post-mining waste as well as the impact of mercury content on the environment. The aim of the paper was to determine the occurrence of the risk of contamination of the environment with mercury compounds found in demolition bituminous coal landfills. Mercury, due to its toxic properties has been classified among the most dangerous substances to human health. There are three groups of sources of mercury release into the environment: natural, anthropogenic and remission. Coal mining, its processing and use in the energy sector has the greatest relevance regarding the pollution of the environment with mercury compounds in Poland. A review of reference literature shows that the average content of mercury in Polish bituminous coal varies within a wide range of 41e399 ppb, which is conditional on the origin, age and type of coal. The production of coal has led to a number of facilities in the form of structurally and age-varied landfills, heaps and mining waste dumps. The content of mercury in postmining waste is in the range from approximately 55 to 380 ppb. The problem of environmental contamination with mercury has attracted considerable interest due to the effects that its concentration have in the biosphere. On the basis of the existing data it has been found that the content of mercury in soils in areas degraded by mining and processing of coal is even 10e16 times higher, compared to the geochemical background. It is necessary to conduct research in this area due to the limited results of research on mercury content in deposited waste from the preparation and flotation of Polish bituminous coals and the potential harmful effect of mercury on the environment. The paper is dedicated to the mercury content in waste from the extraction and processing of bituminous coal.
