Opis:
Rehabilitation of post-industrial areas involves many areas. The area after hard coal mines, requires many specific actions and funds in order to eliminate any remnants of the former infrastructure that is located in this area. The area of Upper Silesia, which includes areas on both the Polish and Czech borders, belongs to the area where the process of underground hard coal mining is being extinguished. As a result of the completion of mining works, the mine areas and adjacent sites begin to undergo transformations. Thus, the landscape of this area changes, various types of land, residential buildings and roads are destroyed. The activities related to restoring the utility value to degraded areas should be carried out consistently, primarily from their inhabitants’ perspective. The rehabilitation of post-mining area and its proper management can bring great benefits to the city and its inhabitants in the future. The publication presents a proposal for land development solutions for the former hard coal mine in Bohumin, Vrbice district in the Czech Republic.

Opis:
The expense of restoring of excavators cutting bodies is increasing these days in the Most Basin area, primarily the replacement of tooth because of abrasion expense. The main reason is the complicated geological situation of overburden rocks, first of all the occurrence of sands and hard structures in the overburden cuts rocks in the deep horizons of open pit mines. Description of the first part of the strength analysis and applicability of 3D models of the tooth serial number 2673 and the tooth ESCO Super V39VYH with application of finite element method (FEM) is the main topic of this article. This research is the stage of the project based on optimisation of the shape and primarily the material used during manufacturing of the mining and ground machines cutting bodies in concrete mining conditions. The research is going on with application of new knowledge in the field of material engineering, metallurgy, cryogenic and nanotechnology. The main target is the increasing of mining process efficiency and the mining machines key node lifetime. Research of the excavator tooth parameters described in this article is very important part of the research.

Opis:
The Brown Coal Research Institute started the solving of the research project based on the optimisation of the shape and material of ground and mining machines in 2018. This research is necessary for increasing of efficiency of mining process in conditions of the Most Basin. The very important part of the research was the geological characteristic of the Most Basin main mining localities. Evaluation of the geological situation of the Bílina, Vršany and Libouš mines (mining of the overburden rocks in the ČSA mine finished) is the first stage of the solving of the project described in this article. The occurrence of sandy strata and the parameters of hard rocks are the most important parameters. The most important used laboratory analyses were the content of crystalline quartz, content of siderite, content of calcite and compressive strength. The location of the overburden cuts with similar mining conditions in different mining localities, very important for need of future research, is described in the end of this article.
