【摘要】 介绍了瞬变电磁法探测采空区的基本原理,结合抚顺东露天矿边坡下存在原井工旧巷,以致严重影响露天矿安全生产的现实问题,采用瞬变电磁法对露天矿北帮边坡旧采区进行了系统探测。根据探测结果进行反演,确定了危险异常区域,为进一步的钻探工作提供了理论支持,避免了由于盲目钻探所带来造价过高的经济损失,为露天矿的安全开采设计与安全控制提供了科学依据。更多还原

【Abstract】 The basic principle of the transient electromagnetic methods(TEM) in goaf exploration was introduced.Combined with realistic problems in Fusun east open-pit mine which goaf cause the serious influence on safety production,old mining area of the north slope in open-pit mine was explored by TEM.According to the detection results,the dangerous abnormal area was determined.It avoids losses from the blind drilling,and it provides scientific basis for safety mining design and safety control of the open pit.更多还原
