   Final report of coal exploration in the Kalshaneh coal deposit
  
  
   Abstract
   This report presents the result of exploration activity in the Kalshaneh coal deposit for reserve estimation. The area is 28 Km2 and is located 3 Km away from the NW of Kalshaneh village. The area is bounded between the Dahaneh-e Mambar and the Shotori Mountains.
   Considering the topography of the area, it is possible to excavate horizontal tunnels for coal extraction. This study focuses on the top 20m coal layer from the earth surface.
   The area has a asymmetric syncline structure trending N-S. The eastern limb dips 45-90 degrees whereas the western limb dips 60-90 degrees. Coal layers belong to the Lower Jurassic Hojedk formation. There are three coal layers in the area that their outcrops range between 800 and 2400m. 80% of reserve in the layer B and 40% of reserve in the layer A is recoverable.
   For completion of superficial data and preparation of 1:1000 and 1:20000 geology maps, more than 64 trenches and 15 low-depth boreholes were drilled. This assessment was based mainly on the samples taken from the boreholes.
   Reserve estimation was done for each block based on the various parameters such as thickness, coal layer structure, structural geology, and coal quality.
