| 摘 要： | 在井巷工程中探明前方或周边涌水是十分必要的。以云南彝良毛坪矿区为例,利用等值反磁通瞬变电磁法(OCTEM)和音频大地电磁法(AMT),探测了帷幕注浆工程轴线以下700 m范围内的含水断裂带的发育情况,意图为帷幕注浆治水工程提供指导意见。通过物探综合分析,探明具有富水性的异常7个。本项研究结果表明,OCTEM法能够识别出较小的含水节理或裂隙,AMT法对大深度含水破碎带较为敏感,两者结合对不良含水地质体探测效果明显。由此可见,综合物探在帷幕注浆治水中应用效果较好,有效查明了含水通道的深部延伸,为帷幕注浆治水提供了目标靶区。

| Abstract: | Taking the Maoping mining area of Yilang in Yunnan Province as an example,the authors used the opposing coils transient electromagnetic method(OCTEM)and the audio-frequency magnetotelluric(AMT)method to detect the development of water-bearing fault zone within 700 m below the axis of curtain grouting project,with the intention to provide guidance for curtain grouting water control project.Through the comprehensive analysis of geophysical exploration,7 anomalies with water-rich were delineated.The results show that OCTEM method can identify small water-bearing joints or cracks,AMT method is more sensitive to large-depth water-bearing fracture zone,and the combination of the two has obvious effect on the detection of bad water-bearing geological bodies.It can be seen that the application effect of integrated geophysical exploration in curtain grouting water control is good,the deep extension of water-bearing channel is effectively identified,and the target area is provided for curtain grouting water control. |
