Feasibility Study Of CSAMT Method In Liaoning CoPPer-Polymetallic Ore Exploration

This paper,taking a copper polymetallic kuandian county in liaoning province as the research object,through the investigation understands,ever conducted in local shallow mining, the mining area near-surface exists high industrial grade copper ore resources,the low degree of geological scientific research surrounding the mining pit considering the mining area is located in the mountainous area,the conventional dc method to suit the requirements of exploration depth and precision,so the CSAMT method exploration in the depth of the mining area,and the feasibility of this method to the research and evaluation.In this paper,on the basis of the reading of vast amount of literature,the development and research status of CSAMT method are discussed,an in-depth understanding the basic theory of CSAMT method and working principle of mastery of CSAMT method in the process of data processing and inversion method of specific work,a detailed analysis of CSAMT method of near field effect,transition zone effect correction method,the static effect and their data.Combined with the geological conditions of mining area,summed up a set of suitable for complicated geological conditions of the work of the CSAMT method system:first in IP scanning, concluded five geophysical anomaly zone,CSAMT survey line layout,secondly combining exploration depth to determine the suitable working parameters,and finally through the IP anomalies with joint inversion of resistivity profile results interpretation,analysis,suggesting that favourable ore-forming and ore-controlling factors.To determine the feasibility of this method,then use the validation in the depth of drilling engineering,and drilling results in conformity with the interpretation result of CSAMT method.Combined with the actual geological conditions,five abnormal is mine causing,basic acceptor structure and secondary structure control of ore bodies in the deep exploration in the mining area of CSAMT method is feasible,the plan layout is reasonable,the results have certain practical value,can be in kuandian region under similar geological conditions of attack of the metal mineral exploration deep blind to get a job offer beneficial reference value and significance.
