综合电法在巨厚松散层覆盖区找煤中的应用效果
|
摘要
巨厚松散层对地震波的吸收衰减作用强烈,采用传统地震勘探找煤效果不好,以可控源音频大地电磁法(Controlled Source Audio Magnetotelluric Method,简称CSAMT)为主的综合电法勘探方法可作为地震勘探的弥补手段。在宁夏香山煤田某巨厚松散层覆盖区找煤工作中,投入了以CSAMT为主、直流电测深法(Vertical Electric Sounding,简称VES)为辅的综合电法的勘探方法,勘查成果经过钻探验证。文章以此为例,通过对勘查成果的分析,说明以CSAMT为主的综合电法勘探工作在此类地区进行找煤工作的有效性。
The huge thick unconsolidated layers have a strong effect on the absorption and attenuation of seismic waves,and the results of coal exploration by using traditional seismic exploration method are not good.The integrated electrical prospecting method based on the controlled source audio magnetotelluric method(CSAMT)can be used as seismic exploration remedies.In the coal exploration work of a thick unconsolidated layers covered area in the Xiangshan coalfield of Ningxia,an integrated electricity exploration method based on CSAMT and supplemented by the technique of vertical electric sounding(VES)was introduced.The exploration results were verified by drilling.The paper uses this as an example to illustrate the effectiveness of the CSAMT-based integrated electrical prospecting work for coal exploration in these areas through the analysis of survey results.
