sarcheshmeh copper mine, with the final reserves of 828 million tons of sulfur ore and average grade of 0.74%, is known to be the largest open pit of iran and most probably the second largest copper mine in the world. this mine is located in the seismotectonic zone of central-iran, and 23 km away from the 150 km long rafsanjan active fault.in this study the vulnerability of the west wall of the...

Annually, hundreds of thousands tons slags are involved in the reverberator and flash smelting as well converting operations Cu-Fe sulfide concentrates to produce matte Sar Cheshmeh copper smelter plant, Iran, disposed landfill cooled air. Due their relatively high average content (about 1.5 wt%), a mineral processing plant based on flotation process has recently been established Cu-sulfide con...

Abstract Synthetic aperture radar (SAR) technology has been widely used in landslide deformation monitoring the past decade. It advantages of high accuracy, a wide range, and flexibility allowing all-weather continuous monitoring. The self-developed S-SAR synthetic (slope radar) is first completely domestic-made slope equipment China, its performance technical parameters are equal to or better ...

Modern Synthetic Aperture Radar (SAR) missions provide an unprecedented massive interferometric SAR (InSAR) time series. The processing of the Big InSAR Data is challenging for long-term monitoring. Indeed, as most deformation phenomena develop slowly, a strategy scheme can be worked on reduced volume data sets. This paper introduces novel ComSAR algorithm based compression technique reducing c...

Natural disasters and human activities are now causing an increase in land subsidence, or surface displacement. The effects of subsidence cause landslides construction cracking. PSInSAR (Persistent Scatter Interferometry) was identified to estimate displacement from a time series Synthetic Aperture Radar (SAR) images. This technique is subset the DInSAR (Differential Interferometric Radar) meth...

The Boundary Element Method has been applied to calculate stress distribution and stability of underground mines for disposal of chemical waste. A case similar to the Stripa mine in Sweden has been considered. The rock mass was granite, with major fracture zones represented by three families of planes mutually orthogonal and 100 meters distant from each other. The pre and post processor GiD [3]...

erosion is one of the important social-economic problems in iraniancatchments that have been posed by surface water vastness and runoff production. so, thestudy of water resources, soil erosion and effective factors is of high importance. gullyerosion also extends in many parts of iran and its study particularly in viewpoint ofsediment yield is therefore very important and should be taken into ...
