Artykuł porusza zagadnienia bezpieczeństwa robót strzałowych i stosowania materiałów wybuchowych przeznaczonych do użytku cywilnego. Zawarto w nim podstawowe informacje dotyczące metod inicjacji detonacji, zużycia środków strzałowych w zakładach górniczych oraz opisano wybrane wypadki i niebezpieczne zdarzenia związane ze środkami strzałowymi, w tym z nieuprawnionym stosowaniem materiałów wybuchowych.

The development of explosives' technology allows their use for civilians, including the mining industry. In 2019, 46.71 million kg of explosives were used in the Polish mining industry, of which more than half (25.5 million kg) were used in opencast mines. From 1990 to the end of 2019, the consumption of emulsion explosives and the use of non-electric initiation systems were continuously increasing. The development of these technologies and the experience of people associated with blasting works allow for their more effective and safer use. However, the accidents related to blasting works still occur. During the analyzed period, there were 92 such accidents, in which there were 22 (out of 170) death victims. Most of the situations resulted from the so-called „human factor", mainly due to the time pressure and the failure to fulfill some basic obligations. Over 90% of the injured people were employed in underground mining plants, which indicates an increased risk in this type of mines. Despite the best security and controls, the risk of theft, loss or destruction of explosives also cannot be fully eliminated. The article describes three such events in Polish mines.

Artykuł przybliża zagadnienia związane z bezpieczeństwem robót strzałowych oraz stosowaniem materiałów wybuchowych (MW) przeznaczonych do użytku cywilnego w zakładach górniczych. Poświęcono go kwestiom prawnym związanym z produkcją, transportem i przechowywaniem materiałów wybuchowych. Ponadto dokonano analizy niebezpiecznych zdarzeń związanych ze stosowaniem materiałów wybuchowych w odkrywkowych zakładach górniczych.

Along with the technical progress in the area of explosive use in the civil operations, the regulations concerning to work safety also had to evolve. They regulate issue related to the transport, storage and use of explosives intended for civil use. Particularly responsible tasks related to this have been entrusted to the President of the State Mining Authority, whose main task is to approve the products for use in mining plants (also about blasting equipment) and keeping a register of explosives intended for civil use. The State Mining Authority is also a market surveillance authority for explosives used in mining. In the 2004-2020 over 1,000 explosives were registered. Equally important tasks were entrusted to the directors of district mining offices. They are related to the issuing of permits for the acquisition, storage or use of explosives. Despite technical proces the expansion of regulations that clearly define the obligations related to the conduct of blasting, there are st accidents resulting from improperly performed blasting. The dispersion of rock fragments beyond the established safety zone should be considered among the most common undesirable effects of the use of explosives in opencast mines. The reason is the incompatibility of the amount of explosives to the mining and geological conditions, as well as the lack of control of the excavation before blasting works. This proves the lack of experience as well as the disregard of the dangers by the persons performing and supervising blasting works. Consequently, it leads to an increase in the exploitation costs of the deposits.
