The main objective of the project ”Monitoring of mining induced surface deformation” (ALOS-RA-94) is to evaluate multi-temporal PALSAR data for land surface deformation monitoring, using interferometric techniques. Differential interferometry using PALSAR data over several mining sites in Germany, Poland and Czech Republic, as well as over alpine landslides in Switzerland and Italy was used to ...
The paper is concerned with the hydrogeological appraisal of the proposed mining operations in theThar lignite field in Sindh, Pakistan. The Thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. In the Thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and m...
