摘要: 为了提升瞬变电磁方法在煤矿井下探测效果,根据电磁波空间场强叠加原理,提出采用多路同步发射方法,提高空间探测电磁波能量,并限制每一路发射机的输出能量以满足防爆要求,有效解决发射能量与防爆要求之间的矛盾。测试试验及现场应用表明:应用多路合成瞬变电磁发射机进行多线框组合发射的方法能够在本安条件下提高发射功率,增强磁场响应强度,提升数据质量,可为煤矿水害事故的预防预测提供技术保障。Abstract: According to the superposition principle of electromagnetic field strength in space, a multi-channel synchronous transmission method is proposed to improve the TEM detection effect in coal mines, which increases the energy density of spatial electromagnetic field and limits the output energy of each transmitter channel to meet the explosion-proof requirements. The contradiction between emitted energy and explosion protection requirements was resolved. Simulation tests and field applications showed that, using the multi-channel synthetic transient electromagnetic transmitter to implement multi wire-frame combining transmission method can increase the transmission power under the intrinsic safety restriction, enhance the magnetic field response strength, and improve the data quality. The synthetic high-power transient electromagnetic transmitter can provide a technical support for coal mine water hazard prediction and prevention.
