- Safe distances from mining plant objects extracting hydrocarbons with boreholes
The article presents the rules and standards defining the rules for the location of mining plant facilities extracting hydrocarbons with boreholes in relation to objects not related to the mining plant operations and changes of these provisions over the years, as well as doubts that arise in their application. In the area of "safe distances" from facilities and equipment related to the extraction of crude oil and natural gas, such as wells, gasoline plants, equipment and installations for drying and desulphurisation of natural gas, crude oil and natural gas compressors, it was noted that these regulations allow certain type of buildings in the vicinity of the abovementioned objects, which in particular in the case of wells may affect their safe operation. In the area of gas pipeline controlled zones, the applicable regulations were cited and the rules applicable to gas pipelines built before December 12, 2001 were explained, indicating the need to clarify them. Regarding other mining plant pipelines (not covered by legal regulations), the provisions and norms used to determine safety zones (belts) are quoted.
- Financing the rehabilitation of brown coal post-mining areas in Saxony
The use of brown coal in Germany was particularly intense in the GDR, where huge effects on the environment. About 120,000 were destroyed here. ha, the water relations were changed significantly, and a lot of waste was deposited in post-mining excavations. After the reunification of Germany, brown coal mines were not able to meet the requirements of a market economy. Agreements based on the Unification Treaty also included tasks related to the reclamation of post-mining areas in the Lusatian brown coal basins and central Germany. Their scope included: reclamation of 224 post-mining excavations, securing approx. 1,200 km of slopes and demolition of 110 industrial plants, as well as restoring proper water relations and remediation of over 1230 contaminated sites. Initially, the Trust Office financed these tasks. Already in 1992, the federal government and the governments of Brandenburg, Saxony, Saxony-Anhalt and Thuringia concluded an agreement on joint financing of the reclamation of brown coal post-mining areas. Coordination of public and private sector institutions involved in this task required the creation of a three-level organizational structure. The first level covers management of the reclamation process by the Steering and Budget Committee for Brown Coal Mining Reclamation. The second level is ensured by Łużycka and Central German Mining Management Company (LMBV), which is the company responsible for remediation under mining law. The third level is the implementation of reclamation activities by private enterprises. As a result of these activities, a marked change in the landscape took place in central Germany and Lusatia. Almost all demolition works were carried out here. The displacement of soil masses and their compaction achieved a high degree of advancement. Only geotechnical demanding work remains to be done. Over 75% of the land reclamation activities have already been completed. Remediation of contaminated land and restoration of the water balance still has to be carried out.
- The use of mining waste for land reclamation on the example of LW "Bogdanka" - Joint Stock Company
The article presents the reclamation of a subsidence trough resulting from the exploitation of hard coal by the Lubelski Węgiel "Bogdanka" mine. Performing the obligations arising from environmental protection regulations, the entrepreneur performed reclamation works based on relevant decisions of environmental protection authorities. The reclamation was carried out in the recreation and tree planting direction. As part of it, a water reservoir (fish pond), pedestrian and bicycle paths, drainage ditches and "green" development through treatment and afforestation of the area covered by the reclamation were made. The reclamation was carried out using mining waste, which was then covered with a reclamation embankment with a thickness of min. 1.0 m from earth masses. The reclamation carried out shows how changed areas of mining activity can be given new natural and landscape values and make them attractive to the local community.
