瞬变电磁法用于检测与识别硐室爆破盲炮的可行性探讨
Feasibility study of the transient electromagnetic method for chamber blasting misfire detection and recognition
摘要
Abstract
In this paper,transient electromagnetic method was used to carry out the feasibili-ty study on the detection and recognition of chamber blasting misfire. First,an electromagnetic background field was established in the test;second,a benign conductor was preset in the chamber,and then the background field was eliminated after the electromagnetic field was mea-sured;finally,the transient electromagnetic field was measured again after blasting;at last, the chamber blasting misfire was detected and recognized by comparing the change of vortex field of the preset benign conductor before and after blasting. The test results showed that:When the buried depth of aluminum box target was no more than 30 m,transient electromag-netic method can clearly identify the position of the aluminum box;when the buried depth of aluminum box was more than 30 m,the buried depth and position of the aluminum box was not sure due to the unknown level of secondary vortex field generated by aluminum box.关键词
