摘要
在青杠林煤矿工作中,利用MSD-1脉冲瞬变电磁仪,选用100m×100m正方形重叠回线装置,观测时窗8～25920μs,采样道数40道进行数据采集。经数据处理,获得该区多测道剖面图及虚拟全区视由阻率剖面图,从中解释其含水岩溶管道3处,含水岩溶空洞2处,节理、裂隙5条。根据依照水患危险程度划分标准该区岩溶管道、空洞的位置及节理、裂隙的贯穿深度,将该区定为中等程度隐患预测区。
During the Qingganglin coalmine prospecting data acquisition, MSD-1 pulse transient electromagnetic apparatus, 100m×100m square superposition loops and 8 -25920μs observation time window and 40 sampling channels were used. The area＇s multichannel sections and virtual apparent resistivity sections have worked out through data processing and on this basis, 3 water-bearing karstic channels, 2 water-bearing karstic caves, 5 joints and fractures interpreted. According to flooding hazard level standard, defined positions of karstic channels, caves and penetration depths of joints and fractures, predicted the area is a medium flooding hazard area.
