The Study Of Method Applied In Exploration For Continued Resources Of The Crisis Mines

The Zhashui YinDongzi Ag-polymetallic mine of Shanxi,which locates in Zha(Shui)Shan(Yang) the second-level sedimentary basin of the Devonian period of north passive epicontinental edge of the NanQinling orogenic belt,is a serious crisis mine,to seek continued resources becomes urgent.It is the model of the seabed hot water jet sedimentary mineral deposit,which is located at the carbonate sedimentary formation to the clastic rock sedimentary formation transition spot hot water deposit lithic facies.The mine includes Ag primarily,and also Cu,Pb,Zn.Ag reserves large-scale,Cu-Pb-Zn reserves medium-scale.All ore bodies locate at the upside of the second section of the DaXigou group,which are controlled by lithic facies obviously and present layered and stable.This article reserchse the geology and geochemistry basing on the main methods to analyze the ore deposit's controlled factors.Then it compares the main geophysics technology and choices the Ground high-precision magnetic survey and CSAMT according to the geological feature and type.By these two methods,identifying the special distribution ofΔT andρfrom 41 to 105.Using exploration works to check the deep abnormal and control the 13,4,7,8 Orebodies,gating certain resources.It shows these two methods are effective.Using Surpac to establishe 3D model ofρand the orebodies.The two models are well fitted in the same coordinate system,which furtherly shows that it's effect to use CSAMT.This paper can be guidance and learn.for the prospecting and sustainable development of the resources crisis mine.
