Coal exploration project in the Mazinu of Tabas
The study area is located in the 56 10' eastern longitude and 33 08' to 33 13' northern latitudes. Four coal bearing zones of the Tabas are among the largest coal reserves of Iran. By a small exploration in the Mazinu area, it is estimated that there is about 630 million tons thermal coal in a 30-Km2 wide area. Exploration has conducted in 12 Km2 of the region.
Kalmard is the main fault system in the area that controls the structural geology of Mazinu area. The main coal bearing zone is a horst-like structure between two faults (FN & FN faults). This structure is bounded between Badamu limestone and Tabas limestone to the west and east respectively. N-S trending folding of coal bearing layers caused the preservation of coal resource. 12 minor faults exist in the area that all of them are the next orders of Kalmard fault. The Mazinu deposit can be divided into lower, middle and upper portions. Maximum reserve (450 MT) is located in the lower portion. There are 18 exploitable coal layers in the area. It is possible to achieve 28 tons coal from each square meter. The estimated deepest coal layer is 600 m below earth surface. Lab tests donít show considerable difference in the quality of lower and upper portions. All coal layers are anthracite in type, that have less than 10% volatiles. The coal product is a high energy, high ash, easy to concentrate product. Thermometry, thermal gradient, physical properties of coal, and several other factors will be studied later. Required water can be supplied from the Kalmard fault zone.
