摘要
为解除地质构造复杂矿井中导水构造通道对工作面安全开采的重大隐患,根据现场条件,采用槽波地震透射法和瞬变电磁法对赵庄煤业3307工作面地质构造及含/导水性进行探测,运用时频分析和层析成像等方法对槽波地震数据进行了处理和解释,采用三维切片技术对瞬变电磁法探测数据进行分析。探测结果表明,槽波地震和瞬变电磁综合物探法可有效探测工作面内部的导水构造,为工作面的水害防治提供了可靠依据。
In order to eliminate the major hidden trouble of water conductive structures for the safe-mining of working face in the complex geological structure of coal mine, according to the field condition, we use the transmission method of channel wave seismic and the transient electromagnetic method to explore the water conductive channels of geological structure in 3307 working face. After that, dealing with the channel wave data and explaining the results through time-frequency method and tomography method, we use 3 D slice technique to deal with the data of TEM. Detection results indicate the comprehensive geophysical exploration technique of channel wave seismic method and transient electromagnetic method could explore the water conductive channels of geological structure effectively, which can supply reliable evidences for the water hazard control and prevention of working face.
