The lead and zinc sample from Goosh-e-Fill mine with 2.4%Pb, 8.0%Zn and 10.0% Fe, was used in different flotation experiments to recover lead and zinc minerals. The valuable minerals in prepared sample were oxidized and the results showed that the lead minerals floated at pH= 9.5 and 11.5, probably it can be due to existence of two or more types of lead minerals. The best result was achieved fo...

Differential SAR Interferometry (D-InSAR) is an effective tool in monitoring land subsidence because of its greater coverage area and better resolution of height change. A series of Japanese Earth Resources Satallite-1 (JERS-1) images from 1992 to 1998 has been used in monitoring the mine subsidence in the test site of this study, one of the important coal mining areas in China. D-InSAR procedu...

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]...
