Özet:

Methane occurrence in coal mines has always been caused to fatal occupational accidents like explosions, fires and suffocations throughout the history of mining. Gas content determination plays an important role in mine safety and mine planning. The purpose of gas content determination was to assess gas outburst potentials and to quantify the magnitude of gas emissions into underground working areas so as to make an appropriate ventilation design. However, determining the gas content of coalbeds are not essential only for mine safety, are also essential for the most important parameter of an alternative energy source and a greenhouse gas. At this point determining the gas content of coalbeds has been becoming more of an issue. Some results about determining the gas content of coalbeds by using direct method in TTK (Turkish Hardcoal Enterprise) Mines where problems have been seen constantly regarding excessive methane emissions are given in this paper
