【摘要】：本文以遼寧省寬甸縣某銅多金屬礦作為研究對(duì)象,通過調(diào)研了解到,該礦區(qū)曾在局部進(jìn)行過淺部開采,近地表存在工業(yè)品位較高的銅礦資源,但采坑周邊的地質(zhì)科學(xué)研究程度偏低,考慮到礦區(qū)地處山區(qū),常規(guī)的直流電法無(wú)法達(dá)到勘探深度及精度的要求,因此采用CSAMT法對(duì)該礦區(qū)進(jìn)行深部勘探,并對(duì)該方法的可行性進(jìn)行研究和評(píng)價(jià)。本文在閱讀大量文獻(xiàn)的基礎(chǔ)上,首先對(duì)CSAMT法的發(fā)展過程和研究現(xiàn)狀進(jìn)行了探討,深入了解CSAMT法的理論基礎(chǔ)和工作原理,掌握CSAMT法在數(shù)據(jù)的處理及反演過程中的具體工作方法,詳細(xì)分析了CSAMT法的近場(chǎng)效應(yīng)、過渡帶效應(yīng)、靜態(tài)效應(yīng)以及它們的數(shù)據(jù)校正方法。結(jié)合礦區(qū)的地質(zhì)條件,總結(jié)出一套適用于復(fù)雜地質(zhì)條件下的CSAMT的工作方法體系：首先在激電中梯掃面得出的5個(gè)地球物理異常區(qū)域,進(jìn)行CSAMT測(cè)線的布設(shè),其次結(jié)合勘探深度要求確定合適的工作參數(shù),最后通過激電異常與反演電阻率剖面圖進(jìn)行聯(lián)合成果解譯,分析并推測(cè)成礦的有利地段及控礦的主要因素。為了對(duì)該方法的可行性進(jìn)行判斷,隨后采用了鉆探工程進(jìn)行深部驗(yàn)證,鉆探結(jié)果與CSAMT法的解譯結(jié)果相吻合。結(jié)合實(shí)際地質(zhì)情況,說明5個(gè)異常都為礦(化)體引起,礦體基本受主構(gòu)造及其次生構(gòu)造控制,在該礦區(qū)進(jìn)行CSAMT法中深部勘探是切實(shí)可行的,其方案布設(shè)是合理的,其成果具有一定的實(shí)用價(jià)值,可對(duì)寬甸地區(qū)類似地質(zhì)條件下金屬礦產(chǎn)勘探的攻深找盲工作提供有利的參考價(jià)值和借鑒意義。
[Abstract]:In this paper, a copper polymetallic mine in Kuandian County, Liaoning Province is taken as the research object. Through investigation and investigation, it is found that the mining area has been excavated in shallow part, and there are copper resources with high industrial grade near the surface of the earth. However, the degree of geological research around the mining pit is low. Considering the mining area is located in the mountainous area, the conventional direct current method can not meet the requirements of exploration depth and precision. Therefore, the CSAMT method is used to carry out deep exploration in the mine area. The feasibility of this method is studied and evaluated. On the basis of reading a large number of documents, this paper first discusses the development and research status of CSAMT method, deeply understand the theoretical basis and working principle of CSAMT method, and master the specific working methods of CSAMT method in the process of data processing and inversion. The near field effect, transition zone effect, static effect and their data correction methods of CSAMT method are analyzed in detail. In combination with the geological conditions of the mining area, a set of working method system of CSAMT suitable for complex geological conditions is summarized. Firstly, five geophysical anomaly areas obtained from the ladder sweep surface in the IP are arranged by the CSAMT survey line. Secondly, according to the requirements of exploration depth, the suitable working parameters are determined. Finally, through the interpretation of the joint results of the induced electric anomaly and the inversion resistivity profile, the favorable areas of mineralization and the main factors of ore-controlling are analyzed and speculated. In order to judge the feasibility of the method, the drilling engineering was used to verify the feasibility of the method, and the drilling results were in agreement with the interpretation results of the CSAMT method. Combined with the actual geological conditions, it shows that the five anomalies are caused by ore bodies, the ore bodies are basically controlled by main structures and their secondary structures, it is feasible to carry out deep exploration in the CSAMT method in this mine area, and its scheme is reasonable. The results are of certain practical value and can provide a favorable reference value and reference significance for the blind exploration of metal mineral exploration under similar geological conditions in Kuandian area.
