摘要
系统介绍了矿井瞬变电磁法多匝重叠式装置超前探测的基本原理和数据处理技术要点,并以文明煤矿回风巷下山口前243 m处掘进头超前探测为例,运用矿井瞬变电磁法探测并圈定的低视电阻率异常区与矿方最后掘进结果相吻合,验证了利用该物探方法超前探测煤矿含水体的准确性和可靠性。与其他方法相比,该方法不仅探测效果好,而且仪器操作轻便快捷、探测方向具有任意性、不受井下探测狭小空间的影响。
In this paper,the authors gave a systematic description of the basic principle and the main points of data processing technology by using the mine transient electromagnetic method and multi-turn overlapping device for advance detection of underground water-bearing body.They took the advance detection data obtained at the heading face 243m away from the dip entry of the return-air way in Wenming Mine as an example and defined that the runoff groundwater existed in the low apparent-resistivity abnormal area which was firstly delineated and finally verified by the mine through drivage,this indicted that the advance detection of underground water-bearing body by using this geophysical prospecting method was accurate and reliable.Compared with other methods,the mine transient electromagnetic method has better detection effect,and the instrument is easy to operate,has the random detection direction and is not affected by narrow space in the mine.
