应用瞬变电磁法对硐室爆破盲炮的检测与识别进行了可行性研究。试验时先确立电磁背景场，然后在硐室中预置良性导体并测得电磁场后消除背景场，在爆破后再次进行瞬变电磁测量。通过对比爆破前后预置良性导体涡流场的变化，实现硐室爆破盲炮检测与识别的目的。试验结果表明，当铝箱目标体埋深不超过30 m时，瞬变电磁检测法可以明确地确定铝箱的位置；当铝箱埋深超过30 m后，铝箱形成的二次涡流场层次不明，不能确定铝箱的埋深与位置。

Application of transient electromagnetic method, carries on the cavern blasting blind detection and recognition of feasibility study. Test to establish the electromagnetic background field, and then in the cavern preset benign conductor and measured after eliminating the background field, in the electromagnetic field transient to do the electromagnetic measurement again after blasting. Benign comparison before and after blasting preset the change of the conductive body eddy current field, realizes the cavern blasting blind shot detection and identification of purpose. The test results show that the target when the aluminum box buried depth of no more than 30 m, transient electromagnetic method can clearly identify the position of the aluminum box; When the aluminum box buried depth after more than 30 m, aluminum box formation of the secondary vortex field level, not sure the deep buried depth and position of the aluminum box.
