| 摘 要： | 邢台矿区属典型的华北岩溶型石炭一二叠系煤田，下组煤普遍受巨厚奥陶系灰岩强岩溶含水层的威胁。根据目前物探方法的特点，决定使用方向性好，对水敏感的瞬变电磁技术探测该矿区水患。针对井下巷道工作条件复杂．干扰因素多的特点，选用两个不同的工作频率25Hz、6．25Hz进行测量。并以显德汪矿1612工作面风巷瞬变电磁侧向探测为例，圈定出其低阻异常区。

| Abstract: | The Xingtai mining area is a typical North China Permo-Carboniferous karstic type coalfield, its lower coal group is generally under threat from the thick Ordovician limestone strong karstie aquifer. According to present geophysical prospecting method characteristics, decided to use the transient electro-magnetic technique with good directivity and water sensitive to explore water hazard in the mining area. In allusion to complicated underground roadway working condition and manifold interferential factors, carried out detecting with 25Hz and 6.5Hz two different assigned frequencies. To take the transient electro-magnetic lateral prospecting in No.1612 working face air entry of the Xiandewang coalmine as an example, worked out its low-resistivity anomalous zones. |
