    Opis:
    Mining activities such as underground exploitation of hard coal deposits and open cast mining are strong factors on groundwater depending on mine life cycle phases. The impact of coal mining activities on groundwater have been reported from many countries. In this case, a vulnerability assessment was conducted base on standard DRASTIC method and its modification DRASTIC MINE (DRASTICM) method. In order to take into account, the impact of mining activities, a new parameter was added which defined the impact of coal seams on the rock mass above, including the degree of its drainage and the range of its impact. In the standard DRASTIC method, the results indicate that groundwater vulnerability with high (38.6%) and very high occurrence classes (16.9% of the area), mostly covers the central part of the cast mine. In contrast, the reclaimed area of the excavation is a low-class area. The DRASTICM method increased the vulnerability index from 3 to 24 on 95% of the area, so a new vulnerability class of extremely high was delineated, which occurred in 1.6% of the area. This indicates areas that should be treated as a priority in order to avoid pollution, and in the final stage to plan activities in the field of the reclamation of mining areas. The results showed that groundwater vulnerability assessment in coal mining areas can be significantly improved.

    Opis:
    Mining activities can have serious negative effects on the environment, these effects occur from the exploration stage to the closure stage of a mine's operation. Nigeria has different minerals and exploration/exploitation of these minerals can affect the environment. The objective of this paper is to consider how the exploration and exploitation of Tin in Plateau and Coal in Enugu has affected the environment. The Jos field (Plateau State) is used as a case study for areas with existing mines and the coal mines at Enugu represent areas with closed mines. The methodology used for this research includes a field survey; direct mapping of mining activities; assessment of the impacts of exploration and exploitation; documentary analysis; and observations. The results include analysis of the mining impacts of Tin and Coal on the environment. It is hoped that the conclusion of this study will enable Nigeria to put in place and enforce certain minimum environmental standards for solid mineral exploration and exploitation. In addition, best management practices for reclaiming surface mines could also be put in place.

    Opis:
    The paper presents an author’s method of eco-efficiency assessment of mining production processes in hard coal mines, which enables integrating results of evaluating both environmental and economic aspects. The proposed method uses life cycle approach to assess environmental efficiency and the result of operating activities to assess economic efficiency. The comprehensive method of assessing miningproduction processes was proposed as the Key Performance Indicator (KPI) in hard coal mines in Poland to be used to support decision making in mining companies.
    W artykule przedstawiono autorska metodę oceny ekoefektywności procesów produkcji górniczej w kopalniach węgla kamiennego, która umożliwia zintegrowanie wyników oceny aspektów środowiskowych i ekonomicznych. Proponowana metoda oceny wykorzystuje podejście cyklu życia do oceny efektywności środowiskowej oraz wynik z działalności operacyjnej do oceny efektywności ekonomicznej. Opracowaną kompleksową metodę ceny procesów produkcji górniczej zaproponowano jako kluczowy wskaźnik efektywności KPI (Key Performance Indicator) kopalń węgla kamiennego w Polsce stosowany do wspomagania procesów decyzyjnych w przedsiębiorstwach górniczych.

    Opis:
    The extraction of minerals, including fossil fuels, is a licensed activity. In the case of strategic fossil fuels owned by the state, such as hard coal, lignite, crude oil, natural gas, a license is issued by the minister responsible for the environment. The minister also signs a mining lease agreement, that is the right to use a mining area, with the entity to which they grant the licence. In the case of resources that are not covered by mining lease, but are subject to land property ownership, such as rock or peat, the licensing authority is the staroste or voivodship governor (depending on the area of the deposit or the volume of the mineral to be extracted). The licensing procedure requires the preparation and completion of extensive documentation presenting the interested entity and the activity it is going to undertake. In the case of licences granted by the minister or governor, the submitted documentation is required to contain a de-posit development plan. The licensing procedure consists in examining the license application along with the attached documentation by the competent authority, as well as conducting arrangements with the interested institutions and supervisory authorities. Commencement of the licensing procedure for the extraction of coal or peat is not limited in time, whereas the granting of licences for the exploration, identification and extraction of hydrocarbon deposits begins only in the form of a time-limited tender. After the licence has been granted, the area covered by its provisions is entered in the register of mining areas. Licences are granted for a specified period of time. An important element to be included in their contents is indication of the requirements for conducting a business in a way that minimizes the negative impact on the environment.
