摘要
在黄土梁峁地貌进行采空区勘探,在目标煤层的埋藏深度已知的条件下,有效、快速地找出其位置,笔者选用瞬变电磁法,通过试验,选择1.5m×1.5m的重叠回线装置,在勘探区内区进行采空区探测。然后再结合区内的地质条件进行分析和解释工作。探测结果表明:瞬变电磁法探测采空区准确可靠,证明小线圈装置施工效率高、效果好。
In order to effectively and quickly find out the location of the gob area under the condition of known burial depth of the target coal seam in loess hilly topography, this au- thor used the transient electromagnetic method and chosed 1.5m X 1.5m overlapping loop device by testing to detect gob area in exploration area. Then combined with the geological conditions in the region, the work is analyzed and interpreted. The results showed that transient electromagnetic method is accurate and reliable for gob area detection. Small coil device is proved to be highly efficient and effective.
