The Application Research Of Detection Methods Of Mined-Out Area

The resources of Iron is important metal mineral in China.But,the underground mineral has been mined,leading to Mined-out area.The Mined-out area damages su rrounding rock easily,including deformation,crack,fragmentation,destruction of arable land and buildings facilities and the ecological environment,bringing potential securit y risks.With economic developing,land is used by people in mined-out area.Geoph ysical prospecting and drilling methods are effective and economic,evaluationg Mined-out area,putting the appropriate measures of mine training.In recent years,demestic and foreign geological workers use geophysical prospe cting methods,getting a lot of practical effect.This paper deals with the basic charact eristics of Mined-out.First of all,the basic principle of geophysical prospecting met hods,data should be acquired.Abnormal area is determined on experimental area.A bnormal area is may mined-out area.Second,drilling situation is the detection of ab normal area,verifying the existence of mined-out area,position,scope and depth.Fi nally,making examples that explain,induced polarization method and drilling,detect Mined-out,guiding Mined-out area tmanagement,land reclamation and utilization.This paper main research direction is as follows:1.explains the instance,includi ngWorking device,Wire layout,electromagnetic property of different formation,Min ed-out area of YangDa railway,result analysis.2.uses technical parameters and,reac hing the decision that analyses date and explains Mined-out area.3.Drilling is basic method,acquiring,identifing of.This paper improves the core drill sampling,observa tion,verifing Mined-out area of making accurate results.
