Abstract
Iran's coal-bearing sediments are within the Upper Triassic to Middle Jurassic Shemshak Group. These sediments are developed in the northern, central and eastern parts of Iran. The most extensive development of these sediments in Iran is called "Tabas- coal bearing basin". This extensive basin is divided into three coal- bearing regions known as Parvadeh, Nayband and Mazino. Coal- bearing sediments exposed in the Parvadeh region consist of Nayband, Ab Haji, Parvadeh and Baghamshah Formations respectively. Nayband formation in the Parvadeh region is divided into five members known as the Gelkan, Bidestan, Howz-e- Sheikh, Howz-e- Khan and Ghadir. Ghadir member with a thickness of more than 1000m consists of some coal- bearing zones. The principal coal zone of Parvadeh region including five workable coal seams is located in the middle part of this member.
    Geological structure of the Parvadeh region is influenced by some major east-west trending faults and is divided into several segments by minor faults. Quantitative and qualitative characteristics of the coal seams. in these areas, exhibit gradual variation with a distinctive trend. Thus, based on the above-mentioned points, Parvadeh region is divided into several mining areas, in which at this preliminary stage of mine- design, five mines with an annual production capacity of 3.5 million tonnes are proposed.
