The Method of Prospecting Unidentified Goaf in Xishimen Iron Ore Mine
In recent years,electrical prospecting method prospecting mined-out area had very big development.Highdensity electrical method,which is focus on the electric profiling method and electrical sounding method,applicable in detecting the plains and shallow in depth 300 meters.The transient electro-magnetic method(TEM) is applicable to 800 meters of detecting depth,but easily distracted.According to the different environments in north area and south area of Xishimen iron ore mine,in north area and south area respectively detected by high-density electrical method TEM,detection results in delineating goaf and combine the approximate scope of traditional drilling projects,and the unidentified comprehensive detection mined-out area.This detection of unidentified goaf is more targeted and production costs reduced greatly.
