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. Chadir member with a thickness of more than 100Gm consists of some coal- bearing zones.
The principle 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 foults. 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.
