摘要
为了防止生产过程中钻孔突水事故发生,保证采煤工作安全,应用瞬变电磁法,在新驿煤矿已掘进巷道内沿煤层和煤层底板向可疑位置发射电磁波,探测分析工作面钻孔确切位置及富水情况。通过探测发现工作面钻孔内含水情况,瞬变电磁法能够准确探测工作区域水文地质情况,为煤矿防治水提供可靠依据。
In order to prevent water inrush incidents during the production process and to ensure the safety of coal mining, the transient electromagnetic method was applied, which was to emit, along the coal seam and seam floor, electromagnetic waves in suspicious location in the roadway. The purpose was to detect the exact location of the borehole and water bearing condition. After detection, we found that there are some boreholes containing a small amount of water. The Transient Electromagnetic Method was helpful in detecting accurately the Hydro-geological situation of the working field, and was able to provide reliable basis for water prevention and control in coal mine.
