Abstract

In recent decades, the subject of gas emission in underground coal mines in many countries is an important subject. Many factors affect in gas emissions in coal seams.Geological and physical structures of coal are affecting on gas emissions'.Also, composition and mineralization of coal, affect in coal PERMEABILITY for different gases. In this study, the relationship between MACERAL composition and coal PERMEABILITY in Tazareh and Parvadeh mines has been studied. Accordingly, a laboratory studies to investigate the relationship between coal composition and coal PERMEABILITY was done. In coal samples, with MFORR equipment the PERMEABILITY test was done. With microscopic analysis, the MACERAL contents of coal such as INERTINITE and VITRINITE have been measured. Accordingly, many coal samples of Parvadeh and TAZAREH COAL MINEs have the pyrite as the dominant mineral matter. Parvadeh coal samples has the average percentage of VITRINITE equal 81.34% and 10.52% INERTINITE. Also, in the Tazareh coal samples in Eastern Alborz coal mines, the average percentage of VITRINITE is 69.31% and INERTINITE is 22.47%.The average percentage of Pyrite content in Parvadeh coal samples in Tabas coal mines is 2.38% and in the Tazareh coal samples in Eastern Alborz coal mines is 2.62%. The PERMEABILITY test results have been shown, which, with increase of INERTINITE contents, the PERMEABILITY of coal is increasing. Also, test results have been shown, there was a reduction in the coal PERMEABILITY with increasing of mineral contents and carbonate contents of the coal. So, the coal PERMEABILITY in Tabas coal samples is more than Eastern Alborz coal samples.
