矿用瞬变电磁法作为一种非接触式探测技术，在矿山地质灾害源预报中发挥了重要作用。受不同条件的限制，矿用瞬变电磁法数据采集仪器均为非矿用本安型，对瞬变电磁技术的应用存在一定的隐患和不便。在大量实验研究的基础上，课题组在采集装置、野外作业方法、数据处理关键技术等方面进行了研究，研制出了我国第一台矿用本安型瞬变电磁系统。通过与国内外相关瞬变电磁仪的检测对比实验，确定了井下瞬变电磁法数据采集装置、野外工作方法和数据处理的关键技术。对YCS40(A)型S瞬变电磁系统的性能可靠性进行了验证，并利用小线圈、小功率、中测深形成了一套矿井瞬变电磁探测技术，解决了巷道掘进和回采工作面水害探测的一些技术难题。多项技术参数对比和矿场检测试验结果表明，YCS40(A)型矿用瞬变电磁系统具有方便、快捷、灵巧等优点，适用于各种水害防治，效果明显。
As a kind of non-contact detecting technique,the mine transient electromagnetic methods have play an important role in forecasting geological disaster sources in mines.Limited by different conditions,the instruments of transient electromagnetic methods for data collection in mines are all non-mine intrinsic safe type.It has some hidden troubles and inconvenience for TEM technology application.On the base of many experiments and studies,the study team has carried on research about the collecting device,and the method of field work,and the key technology of data processing,and developed the first mine intrinsic safe type transient electromagnetic system of China.Through detection and contrast experiments with home and abroad relevant TEM instruments,YCS40(A) s reliability of performance is validated.And a suit of mine transient electromagnetic detection technology is formed by using small coils,small power and medium sounding.It can solve some technology problems of water disaster exploration during laneway tunneling and workface mining.The many results of the technical parameter contrast and detecting experiment in mines show that the YCS40(A) type mine transient electromagnetic system has some merits such as handiness,shortcut and smart,and the technology is fit for all kinds of water disaster prevention and controlling.Its effect is obvious.
