| 中文摘要: |
| 瞬变电磁法在探测地下含水目的体时有非常敏感的反映，应用于井下超前探测时对煤矿掌子面在掘进前方的水体探测灵敏又准确。选择适当的井下瞬变电磁探测装置参数，可以准确又高效地查明对煤矿开采存在安全隐患的水体(如老窑采空积水区等)，从而达到预报巷道前方富水情况的目的。扇形成像能直观准确地反映巷道掘进工作面各个方向及围岩的富水情况，为煤矿井下生产防治水工作提供可靠依据。 |
| 英文摘要: |
| Transient electromagnetic method has a very sensitive reflection in detecting underground water-bearing bodies，and is sensitive and accurate in the detection of water in front of coal mine face when applied tounderground advance detection. Selecting the appropriate device parameters of the underground transientelectromagnetic detection device can accurately and efficiently identify the water bodies that have potential safetyhazards for coal mining(such as the goaf and stagnant water areas，etc.)，so as to achieve the purpose of predicting the water-rich situation in front of the roadway. The fan-shaped image can directly and accurately reflect the water-rich condition of the front of the roadway and the surrounding rock，and provide a reliable basis for water prevention and control in coal mine production. |
