摘要
对于水文地质条件复杂的矿井,巷道掘进过程中要求"有掘必探",通过跟踪覆盖方式进行连续超前探测与预报,为巷道安全生产提供技术保障。矿井瞬变电磁法为非接触式探测,其多匝小线框发收系统有利于井下掘进工作面连续跟踪超前探测施工与应用。其数据采集时保持每一次探测使用的仪器设备、现场工作技术方法、数据处理与解释方法等过程基本一致,确保探测预报条件的相对稳定,进一步提高对含水异常体预测的可对比性和准确性。淮南及新集矿区煤岩巷道探测结果表明,采用瞬变电磁法连续超前探水,对巷道前方含水异常体的预报效果良好,所判断的含水异常区段为超前钻探及防治水技术措施制定提供依据。
During tunnel driving the principle＇ where is tunneling, there is detection＇ is required for mines with complicated hydrogeological condition, a technology can be provided for safeguarding the tunneling through the continuous advanced detection method in ‘follow and cover＇ way. As a non-contact detection the mine transient electromagnetic method has unique superiority during detecting construction and application ahead of tunnel through the transmitting and receiving system of multi-circle small wireframe. During data collecting some key links need to keep fixed and identical, such as surveying instrument and equipment, field working technology and method, data processing and interpretation method, and so on. It can keep relative steady of detection and forecasting condition, and diminish u system error~＇ and improve the detecting contradistinctive and veracity for the water containing body. The detecting practice and its results in the coal and rock laneway of Huainan and Xinji mine fields show that the advanced detection by transient electromagnetic method through continuous following way and has good judgment and effect for the abnormal water containing body ahead of the tunnel. It can provide help for advanced drilling and technical measure draft of water control according to forecasting abnormal water containing zone.
