Öğe Investigation into the influence of microwave pre-treatment on coal crushability using various strength tests(TMMOB Maden Muhendisleri Odasi, 2017) Toraman, O.Y.; Delibalta, M.S.In the present study, the effect of microwave energy on crushability of high ash low rank Turkish coal has been investigated. Coal samples were treated by microwave at a frequency of 2.45 GHz with 0.80 kW power level and different exposure times (15-240 s). In order to determine the crushing resistance of lignite coal samples treated by microwave oven, the various strength tests (ISI, CI, Is(50)) were applied for each treated and untreated sample and compared with each other. Experimental results have shown that significant increases in crushability were achieved when the coal samples were exposed to microwave radiation.Öğe Lobby activities against to coal and technological reality(Baski, 2019) Delibalta, M.S.; Toraman, Ö.Y.Coal is the world's richest reserve and the most reliable fossil fuel. At the same time, it has a competitive cost between energy sources. Clean coal technologies; increasing energy efficiency, reducing greenhouse gas emissions caused by coal, and thus coal is becoming a cleaner fuel. Because of the energy efficiency gains, European countries consume less energy more than 10 years a decade ago. Also; in European countries, fossil fuels are less needed because of energy savings and renewable energy development faster than expected. However, despite its declining contribution, fossil fuels still continue to be the most important energy source in Europe. Despite all these developments; there is an increasing opposition to open pit and underground coal mines worldwide. Protests are organized in different ways by anti-coal lobbies; human chains, barricades, walks and online campaigns are some of these. But; Turkey's dependence on foreign energy and increasing balance of payments deficit due to energy imports, and maintaining the high share of coal in electricity generation system, using domestic coal reserves for the country of our 2023 targets in line is planned to contribute to the national energy system. Turkey last 5 years, the current account deficit 219.8 billion, while that of the 213 billion dollars in energy bills confirms this fact. In this research; anti-coal lobby activities and technological reality are discussed and objective solutions are offered to sector stakeholders.

In this context; the mining sector, which is one of the leading industries in the societies with the economic, social and environmental impacts, is also affected by these changes. In fact, the mining industry has a long process of technological change. Especially in the last century, many basic changes have been experienced in the acquisition of mineral excavations, minerals and metals. But; It is also known that the mining sector due to the reduction of high-grade ores, the necessity to work under difficult conditions, changing market conditions, new trends, increasing social expectation and environmental pressure face various financial, technical and operational challenges. On the other hand, new technologies are emerging rapidly. It is only possible that the mining sector is able to continue its existence and maintain its activities by finding and implementing innovative solutions in its field. The fact that the mining sector is innovative is not a preference but a necessity. Innovation; to meet the changing requirements and increasing expectations, to reduce the uncertainties arising from the nature of mining, to increase productivity and to be present as an important tool by the mining enterprises. All stakeholders are responsible for developing and implementing innovative approaches in the mining sector. In this research; Turkey and the world in the process of development of the mining sector by taking new paradigms, solutions are offered.

In coal opencast production, with the rise of surface water and ground water level large or small ponds are composed. The most important environmental problems of these ponds are low pH (acidic characteristic) and high metal concentrations (Fe, Mn, Al, Cu, Pb, Zn etc.) of these ponds, besides the sulfide minerals containing (S04) and the waste materials. These ponds needed to be rehabilitated for is one the sustainability of natural resources. In this study, the average pH values 6.22-7.79, turbidity (NTU) 0.63-6.71, sulphate content 840-1720 mg/L, KOI 2.27-61.5mg/L and electrical conductivity 1.72 -2.71 mS/cm have been measured during the monitoring study of three different lignite opencast mine post-production lakes of the TKI -GELI and YLI. The results were evaluated within the framework of relevant laws and regulations. Analyses were performed in three-month periods.Öğe Technological and ecological developments in the modern thermal rower plants(Chamber of Mining Engineers of Turkey, 2013) Delibalta, M.S.; Toraman, Ö.Y.The rapid increase in worldwide energy demands and its environmental impacts directs countries for more strategic energy policies. In terms of environmental impact of energy and security of supply, there is no source which has zero risk. In 21 century, coal is regarded as the world's most important and reliable source of energy. Our country is facing a serious energy supply security. In this process, the most rational thing can be done is to use the limited resources efficiently, economic and ecologically. Today, in the level achieved technologically, the capacity of conventional thermal power plants must be definitely improved and required rehabilitation. Carbon capture and storage (CCS) techniques have been developed the concept of traditional availability of fossil resources. Furthermore, to adopt the terms of mitigation of carbon dioxide (CO2), the use of different areas of CO2 such as chemical, biological and biotechnological products, has been investigated. It can be seen in western European countries the best practice examples of this. In this study, in order to contribute our country's energy policies and strategies and acquire new technologies to the sector, technological and ecological developments in modern thermal power plants were examined.
