22、向扇形探测掘进头巷道上下探测控制距离为60100米。三、工作方法与技术要求根据近年来我所矿井物探理论研究及工程实践表明：探测含水异常体采用矿井瞬变电磁法是最佳选择。故本方案亦采用本质安全型瞬变电磁仪。瞬变电磁法（TEM：Transient Electromagnetic Method）是一种脉冲感应类电法，属于时间域电磁法。它通过不接地回线向勘探目标发送一次磁场，测量一次场激励电源关断后一段时间内的二次磁场变化，通过二次磁场衰减变化的信号特征来解释和反演掘进面前方的介质结构的性状。瞬变电磁法的激励场源主要有两种，一种是回线形式（或载流线圈）的磁源，另一种是接地电极形式的电流源。下面以均匀大地的

23、瞬变电磁响应为例，来讨论回线形式磁偶源激发的瞬变电磁场，从而阐述瞬变电磁法测深的基本理论。在导电率为、导磁率为的均匀各向同性大地表面敷设面积为S的矩形发射回线在回线中供以阶跃脉冲电流 （1）在电流断开之前（时），发射电流在回线周围的大地和空间中建立起一个稳定的磁场，如图3所示。图3 矩形框磁力线在t=0时刻，将电流突然断开，由该电流产生的磁场也立即消失。一次磁场的这一剧烈变化通过空气和地下导电介质传至回线周围的大地中，并在大地中激发出感应电流以维持发射电流断开之前存在的磁场、使空间的磁场不会即刻消失。由于介质的欧姆损耗，这一感应电流将迅速衰减，由它产生的磁场也随之迅速衰减，这种迅速衰减的磁场又

24、在其周围的地下介质中感应出新的强度更弱的涡流。这一过程继续下去，直至大地的欧姆损耗将磁场能量消耗完毕为止。这便是大地中的瞬变电磁过程，伴随这一过程存在的电磁场便是大地的瞬变电磁场。选用了煤炭科研研究总院重庆研究院自行研制的本质安全型YCS-40瞬变电磁仪，该套系统完全能够满足本项目的要求，其瞬变电磁仪主要技术指标如下：工作频率：225Hz、75Hz、25Hz、8.3Hz、2.5Hz、0.83Hz、0.25Hz；发射电流：1A20A，发射供电电压12V48V；记录（时窗）时间：0.008ms864ms；叠加次数：322048；测道数：40道；存储容量：2048个测点；传输接口：RS-232C串口、USB口；传输格式：自定；传送速度：28.8K/s。测量装置可根据具体情况作出相应的调整，一般情况下采用重叠回线装置，偶极装置；发射线框和接受线框采用多匝小回线圈，必要的情况下接受线框根据工作需要也采用相应的磁探头。掘进头探测形式扇形探测方式，分水平和垂直两个方向扫描
