摘要: 矿井2052工作面靠近五煤风氧化带,巷道掘进过程中出现不同程度的煤层冲刷变薄甚至消失,为了解工程地质情况,在胶带巷掘进迎头和侧帮采用井下三分量多测线联合观测,将现场采集的数据处理后,绘制出相应的地震剖面和三维数据体视图,据此推算出迎头前方约90~120m存在异常反射带,侧帮异常界面深度介于24~36m之间。经现场钻探验证分析,风氧化带边界位于胶带巷靠工作面一侧30m范围内,而迎头未能探测到煤层,建议在原探点掘进约50m后再进行探测。

Abstract: The design working face closed to the oxidation zone of No.5 coal seam. During the tunnel excavation, the coal seam was looked thinner even disappear in the end, so the three-components & multiple survey lines observation system was adopted. Three parallel survey lines were arranged on the heading face, and two were arranged on the right sidewall. After datum processing, the corresponding seismic sections and 3D datum views were drew, which showed that the abnormal reflection bands located between 90 to 120 meters ahead of the heading face, which located between 24 to 36 meters depth in the right sidewall. According to the four validation holes, the oxidation zone located within 30 meters depth in working face, and took detection at heading face after excavating 50 meters forward again.

Key words: seismic wave reflected technology, advance detection, oxidation zone
