to Iranian mining industry and the national economy. Alborz Sharghi is a major coal company in north-east Iran that produces coal from many mines in the region including Tazareh, Razmjah, Razi and Gheshlagh. The coal produced by these mines is washed in Alborz Sharghi coal washing plant in order to raise its quality and remove any impurity.

Coal washing factories may create serious environmental problems due to pyrite oxidation and acid mine drainage generation from coal waste piles on nearby land. Infiltration of pyrite oxidation products through the porous materials of the coal waste pile by rainwater cause changes in the conductivity of underground materials and groundwater downstream of the pile.

INTRODUCTION. Mining is particularly hazardous because of the nature of the work carried out. Averaging among all occupations in mines, underground coal mining activities are the most hazardous with very high risk Shahriar et al., 2006.Surface mining is heeded to be more favourable and dominant than underground mining, particularly in safety, meaning, occupational risk in underground is much ...
Abstract The Karmozd and Kiasar mines are two major coal producing areas in the central Alborz coal-bearing field, northern Iran. This study focused on the mineralogy and geochemistry, with respect to the mode of occurrence of elements in feed coals and element partitioning during coal preparation. The low sulfur content in the coal seams indicates a non-marine origin, i.e. deposition in ...

Dec 10, 2020 Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earths surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nations coal reserves and to produce about three times more coal in one hour than in 1978.

Jan 16, 2015 Abstract. The Sangrud underground mine is located in the west of the Alborz basin that has been mined since 1971. The concentrations and distribution patterns of rare earth elements REEs in coal samples from the Mazino mine were studied by inductively coupled plasma mass spectrometry ICP-MS. The concentrations of REEs in coal samples range from 2.1 to 117.22 ppm with average
Mar 09, 2017 The eastern Alborz coal mines are located in the Alborz Mountains. They include two major mining areas including Tazareh including Pashkalat, Kelariz, and Razmja mines and Olang. In order to classify the coal spontaneous combustion potential in the Eastern Alborz coal mines by means of the FDAHP approach, the Pashkalat, Kelariz, and Razmja coal fields of Tazareh were selected
