文章以山西省临汾矿区为例,针对2号煤层及9+10号煤层存在采空积水区的情况,采用可控源音频大地电磁法和瞬变电磁法进行综合电法探测。首先利用可控源音频大地电磁法对构造反映相对明显的优势进行探测,然后结合瞬变电磁法对含水体敏感的特征进行探测,最后两种结果相互补充,进行综合分析解释,准确圈定勘查区内主采煤层采空积水区域及断层等构造的含/富水性,为采空区治理提供科学依据,保证煤矿的安全、高效生产。
Taking Linfen mining area in Shanxi Province as an example, aiming at the situation that there is a hollow area in No.2 coal seam and No.9 +10 coal seam, the article adopts the controllable source audio frequency electromagnetic method and transient electromagnetic method to carry on the comprehensive electrical detection. First of all, we use the controllable source audio-frequency MT method to detect the relative obvious advantages of tectonic reflection and then detect the characteristics sensitive to aquifer by TEM. The last two results complement each other, and make a comprehensive analysis and interpretation to accurately define the exploration area The main mining seam emptying water area and fault structure such as water-rich, providing scientific basis for goafs governance, to ensure the safe and efficient production of coal mines.
