Environmental pollution caused by coal mining operation sharmful and toxic elements Sangrood series with the release of mineral processing and tailings deposit sit into the hydrological system (surface and underground) and soil is. Complications such as ulceration, skin damage and cancers of the nasal tract can be dangerous due to high levels of arsenic in drinking water, especially in these areas. The aim of the present study was to investigate the environmental effect of Arsenic on Sangrood loshan mine which is one of the active mines in province. Sampling was done on 60 soil types and 14 water samples in 4 stations in the mine zone. The results of the present study showed that the level of Arsenic element in the sampling stations is more than standard level and permissible limit. Sulfur content of the coal in this area have been moderate to high mainly pyrite. Arsenic concentration sin soils greater than rocks. Many compounds are readily soluble in water and can contaminate water.

Knowledge of the local stress field in a region is important in the structural and affecting factors on structural kinematics studies. Therefore, in this paper after describing the basic theoretical principles of stress inversion method from slickensides, it was used field measured heterogeneous fault –slips as raw data to determine the average state of the principal stress axes in order to analyze the regional geodynamic situation of this area. The results of the reduced stress tensor from fault-slip measured data, show 21/156، 64/012 and 14/251 states for σ1، σ2 and σ3 axes respectively. The results of analysis of these data show substantial agreement between the determined principal stress axes and recent tectonic research in this region.
