Study of Remote Sensing Monitoring Concerning Geological Environment of Major Metallogenic Belt and Mining Concentrations in the Northern Qinghai Province

A study was implemented for the sake of geological environment status and development trend concerning metallogenic belt and mining concentrations by interpreting materials via means of DEM,IKONOS,QUICKBIRD,WORLDVIEW-2 and SPOT-5.The result of this has shown that salt lake exploitation holds the largest proportion,followed by coal mining,and areas shared by both coal mining and salt lake see a rapid growth.Geological disasters caused during mining exploitation are mainly located in coal mining area,they are shown as collapsed pits,splits,cracks(potential),debris flow(potential),ground collapse(potential),and so on.Forms of environment pollution are water pollution,dust pollution and tailings pollution in particular.
