Coal Mine Hidden Disaster Detection Based on Opposing Coils Transient Electromagnetic Method
Hidden water disasters seriously affect the construction safety of coal mines and the life safety of technicians. In order to find out the spatial distribution of air-filled goaf and water-filled goaf in coal mines, opposing coils transient electromagnetic method (OCTEM) with high detection accuracy...

| description | Hidden water disasters seriously affect the construction safety of coal mines and the life safety of technicians. In order to find out the spatial distribution of air-filled goaf and water-filled goaf in coal mines, opposing coils transient electromagnetic method (OCTEM) with high detection accuracy, high resolution, high sensitivity to abnormal bodies, and fast detection speed is used to carry out research. Through field data acquisition and inversion processing, the inversion profile, slice map, and three-dimensional shape rendering map of each survey line are obtained, and then the geological data are analyzed and explained. Finally, two low-resistance anomaly areas are delineated. One is speculated to be the old kiln goaf, and the other is speculated to be the water-filled goaf in the planning area in the next 5 years. After drilling verification, the speculation results are in good agreement with the actual situation. OCTEM provides an innovative technical basis for the detection of hidden hazards in mines, which has broad application potential in the field of mine exploration. |
