Acquisition and processing of energy and their impact on the human environment, with particular emphasis on atmospheric pollution

Abstract: One of the major problems of the modern world is environmental pollution. The progress of civilization increases the demand for energy, however, the process of its production has a great impact on the environment. Unfortunately, the production and usage of solar energy has its limitations, therefore, the combustion process currently has the largest share in energy production. As a result of burning fossil fuels, the concentration of CO2 in the atmosphere has increased significantly in recent years. However, in order to assess the speed and magnitude of this increase, it is necessary to take into account the carbon cycle in nature. This is especially important when discussing the prevailing belief that increasing CO2 concentration is the atmosphere is a major cause of global warming. In this article I present a critical analysis of the contribution of the increased CO2 concentration to global warming based on the energy balance of the Earth's atmosphere taking into account also other factors that have an impact on this process.

Key words: global warming, greenhouse effect, solar constant

Environmental impact of mine dumps. Example of mine dump „Marcel” in Radlin

Abstract: The article aims to present the impact of mine dumps on the natural environment, by discussing the legal provisions regarding the operation of these objects, as well as analyzing the case of the exploited mine dump. The first part concerns the provisions of the Act of 10 July 2008 on extractive waste and the Act of 14 December 2012 on waste. It presents in detail what legal actions should be taken at the next stages of the mine heap operation as an object neutralizing mining waste, i.e. waste from exploration, recognition, extraction, processing and storage of minerals from deposits. Legal solutions that deserve special approval were indicated, as well as those whose change should be rethought. Waste processing was also discussed as a possible method of dealing with mining waste. The second part analyzes the functioning solution, which is a heap of mining waste at the existing KWK ROW Ruch "Marcel" PGG S.A. in Radlin. The object's impact on the environment and its elements were identified, especially people in their place of residence and landscape.

Key words: mine dump, mining waste, waste processing

Selection of main fans for the target of the X mine based on analysis and calculation of the ventilation network

Abstract: The article analyzes and calculates the current and future ventilation network of the X mine in order to select the parameters of the main fans that should be used in the target model of the X mine after the liquidation of the necessary mining excavations infrastructure and adaptation of the mine to the role of a central underground water pumping station which is a protection for neighboring mines and mining plants. The article presents the results of measurements of the parameters of the current ventilation network of the Mine X and the target model network using the AERO-2014D program of the company POK "Zachód" Spółka z o.o. Simulations of network parameters in the target model included the liquidation of two shafts and unnecessary mining excavations. The tests were carried out for various types of main fans. The obtained results enabled the selection of an optimal main fan meeting the assumed ventilation requirements in the future target model of the X mine.

Target dewatering model liquidated coal mines, in the Upper Silesian Coal Basin

Abstract: The process of liquidation of mines and the restructuring of coal mining in the area of Upper Silesian Coal Basin – due to protecting active mines – not eliminated the problem of dewatering abandoned coal mines. Implemented in the years 90. dewatering model, was based on the existence of hydraulic connections between active and liquidated coal mines. The current situation of mining in the area of Upper Silesian Coal Basin and the experience of SRK S.A. – COAL MINES RESTRUCTURING COMPANY & CZOK Department (Central Plant of Dewatering Mines) SRK CZOK in the field of mine drainage, prove that this model requires verification and improvement. On the basis of the current mining and hydrogeological situation, SRK S.A. proposes to Target Dewatering Model all mines of Upper Silesian Coal Basin, based on separating 9 drainage areas, with one district pumping station for each of them. The success of its implementation, requires the involvement and participation of all mining companies and need to take the proposed measures before the liquidation of the mine. Target Dewatering Model, will optimize and reduce the cost of protecting neighboring active coal mines against the threat of flooding.

Key words: liquidation of mines, dewatering systems, water hazard, Target Dewatering Model

Implementation of innovative technology of goaf inertisation using inert gas mixture obtained through gas engine exhaust gases purification


Abstract:
The paper presents implementation of the project of innovative and efficient technology for inertisation of active or sealed-off longwalls in underground mines, using an inert gas mixture obtained through gas engine exhaust gases purification, which prevents endogenous fires. The project consists of a single stage of industrial research and two stages of development, which include construction and demonstration of the prototype exhaust gas purification plant. The main feature of the technology is using exhaust gases produced by methane engines, which allows high efficiency of producing inert gases. In addition, integrating carbon dioxide and nitrogen in the correct ratio allows fully exploiting the advantages of each of the gases. As a result, by allowing generation of much larger amount of inert gases in a unit of time compared to the available technologies and by combining the physicochemical properties of both nitrogen and carbon dioxide in a single mixture, the innovative technology considerably increases the efficiency of fire prevention, lowering the probability of an endogenous fire occuring. In the context of ecology, innovative inertisation technology of processing and reusing exhaust gases produced by methane engine will decrease pollutant emission in mining. Thanks to low energy consumption it will also decrease the inertisation costs.

Key words: endogenous fire, fire hazard prevention, efficient inertisation, catalytic purification of gas engine exhaust gases

Abstract:
The article presents, in an approachable way, selected issues related to the method of the ordinary kriging, which is widely used for the estimation of mining resources. In particular, such properties of the ordinary kriging were described, which are usually less known but determine its usefulness and accuracy. Particular attention was paid to the role of kriging variance, which is a measure of the accuracy of results obtained using the ordinary kriging. The possibility of using the kriging variance for planning measurement networks was also discussed.

Autoinvent – a modern system supporting the work of mining surveyors, increasing work safety and efficiency


Abstract: 
The article presents a prototype of a modern system called AutoInvent, that allows for the automation of the mineral resources inventory process by measuring the volume of stacks using an unmanned aerial vehicle. In order to increase the accuracy of the data, a fusion of innovative measurement technologies was used: 3D laser scanning and lowaltitude photogrammetry, as well as the integration of two methods of precise positioning: GNSS satellite measurements supported by RTK network corrections and precise laser total station measurements. Automation of the measurement process increases the safety of mining surveyors and shortens the time needed for field work by reducing the need for people to be personally present on the stack. The project co-financed by European Union from European Regional Development Fund within the Smart Growth operational Programme 2014-2020. The project carried out within National Centre for Research and Development call: INNOSBZ.

Key words: photogrammetry, laser scanning, unmanned aerial vehicle, proces automatization
