Abstract: The computed tomography (CT) is a non-destructive technique that can provide information of internal structure of coal in 2D, this technology is now widely used in geoscientific research. This technique is used for the measuring cleat dimension and pore width of the coal. The slicing study of Thar coal shows that the length of cleats in various seams ranges from 0.5mm to 5mm and the aperture of these cleats vary between 0.1mm to0.5mm. The porosity also plays an important role in storage and production of coalbed methane, the size or width of pores in coal under investigation ranges between 0.1mm to 0.7mm. The present investigation shows that seam III and V of the Thar coalfield can be considered as viable as hold a potential for CBM resources, however, the coal samples from these seams need to be analyzed for the presence of methane
