Modeling of ECBM recovery from Amasra coalbed in Zonguldak Basin, Turkey

2009-01-07
Zonguldak coal basin is the only productive hard coal basin of Turkey. The eastern part of the basin is called as Bartin-Amasra District, which has deeper coal seams. The depth and difficulty of mining these coal seams make this district an important candidate for coalbed methane (CBM) recovery. However, there is not enough reservoir data for modeling purposes. In this study, the lithologic information collected for coal mining industry was used to determine the correlations and the continuity of the coal seams. The lithologic information was examined and the depths of the coal seams and the locations of the exploration boreholes were used to perform a reliable correlation using a new method. As a result of the correlation study, 63 continuous coal layers were found. A statistical reserve estimation of each coal layer for methane was made by using Monte Carlo simulation method. The initial methane in place found in the coal layers both in free and adsorbed states were estimated using probabilistic simulations resulted in possible reserve (P10) of 2.07 billion m(3), probable reserve (P50) of 1.35 billion m(3) and proven reserves (P90) of 0.86 billion m(3).

Development of a GIS-based monitoring and management system for underground coal mining safety
Şalap, Seda; KARSLIOĞLU, MAHMUT ONUR; Demirel, Nuray (Elsevier BV, 2009-11-01)
Coal mine safety is of paramount concern to mining industry. Mine accidents have various causes and consequences including catastrophic failure of mine, substantial economic losses and most notably loss of lives. Therefore, any initiative in mine monitoring is of vital importance for progressing safety surveillance and maintenance.
Analysis of roof fall hazards and risk assessment for Zonguldak coal basin underground mines
Düzgün, Hafize Şebnem (Elsevier BV, 2005-10-17)
The roof fall hazards are frequent problems of underground coal mines, which are generally unpredictable due to the associated uncertainties. These uncertainties, which arise from geological and stress conditions and mine environment, make the control of roof fall hazards difficult in underground coal mines. The most efficient method for coping with uncertainties in roof fall hazards is the use of risk assessment techniques. In this study, a risk assessment and management methodology is proposed for roof fa...
Assessment of shrinkage-swelling influences in coal seams using rank-dependent physical coal properties
Balan, Huseyin Onur; Gumrah, Fevzi (Elsevier BV, 2009-01-07)
Characterization of coal reservoirs and determination of in-situ physical coal properties related to transport mechanism are complicated due to having lack of standard procedures in the literature. By considering these difficulties, a new approach has been developed proposing the usage of relationships between coal rank and physical coal properties. In this study, effects of shrinkage and swelling (SS) on total methane recovery at CO2 breakthrough (TMRB), which includes ten-year primary methane recovery and...
Modeling of mogan and eymir lakes aquifer system
Yağbasan, Özlem; Yazıcıgil, Hasan; Department of Geological Engineering (2007)
Mogan and Eymir Lakes, located 20 km south of Ankara, are important aesthetic, recreational, and ecological resources. Dikilitaş and İkizce reservoirs, constructed on upstream surface waters, are two man-made structures in the basin encompassing an area of 985 km2. The purpose of this study is (1) to quantify groundwater components in lakes’ budgets, (2) to assess the potential impacts of upstream reservoirs on lake levels, and (3) to determine effects of potential climatic change on lakes and groundwater l...
Modelling of ECBM recovery from Amasra Coalbed in Zonguldak Basin, Turkey
Sınayuç, Çağlar (2018-01-01)
Bartin-Amasra coal field was found convenient for enhanced coalbed methane (ECBM) recovery among the other fields in Zonguldak Coal Basin, Turkey. The lithologic information were examined and the depths of the coal seams and the locations of the wells were visualized to perform a reliable correlation between 63 coal layers existed in the area. The initial methane in place found in the coal layers both in free and adsorbed states were estimated using probabilistic simulations resulted in possible reserve (P1...
