- Safety of blasting works in mining plants - part II
The article presents the issues related to the safety of blasting works and the use of explosives intended for civil use in mining plants. It was devoted to legal issues related to the production, transport and storage of explosives. Moreover, an analysis of dangerous events related to the use of explosives in open-pit mines was performed.
- Influence of air temperature and humidity in underground workings on the impedance of the human body
The specific climatic conditions occurring in deep mines make the human body highly susceptible to the effects of shock current in electric accidents. The well-being and the rate of fatigue as well as the abundance of human sweating depend on the mutual system of temperature, humidity and air velocity in the excavation. The pathological effects of electric shock occurring in accidents are conditioned by the value of the touch voltage and the impedance of the body at the moment of shock. The article presents changes in the value of human body impedance caused by the influence of temperature and air humidity in underground workings.
- Forest reclamation of the excavation area after sand exploitation on the example of slope 20/III in field II of the "Szczakowa" Sand Mine
The article on the example of the 20/III slope of field II of the Szczakowa Sand Mine and the description of sand mining systems (longwall and longwall sand mining systems) presents the effects of the reclamation. Works related to basic reclamation included, inter alia, forming slopes, building economic roads, retention reservoirs, a network of drainage ditches and culverts. On the other hand, detailed reclamation included, among others, mineral fertilization and sowing legume and legume plants, and in the final planting: acacia robinia, pine (common and black), gray alder, ash-leaved maple, birch and larch and such shrubs as: Siberian carrageenan, narrow-leaved olive, acacia bladder, bird cherry (common and American), and rowan. Educational paths were also marked out, showing the return to biological life in the reclaimed areas. After the rehabilitation of the slopes, forest habitats were created similar to the dry coniferous forest or even the poorer variant of the fresh coniferous forest. Its effects to date prove the effectiveness of the methods used, leading to the creation of forest habitats in some respects (e.g. resistance to pollution) exceeding natural habitats and contributing to the increase of the ecological value of landscape landscapes by introducing mixed forests and the formation of new biocenoses with a greater number of species plants and animals.
