Abstract

The invention discloses a transient electromagnetic method for detecting land Japanese abandoned chemical weapons. The method comprises the steps that a known and precisely positioned point without any obstructions and signal interference in the surrounding is selected, and a base station and a moving station are erected at the point; the moving station and the base station are connected and synchronized; a standard point is selected for coordinate correction; after the coordinate correction is completed, setting-out is carried out; a detection coordinate system is established; the base station is fixed; relative coordinates are input; the coordinate axis value and the positive direction are determined according to a detection scheme; a transient electromagnetic instrument is used for detecting in a detection area; the position of a measuring line and the distance between measure points are determined according to the detection scheme; the measurement network of the whole area is drawn; the position of each measure point is marked, and successive measurement is carried out until the measurement of the whole detection area is completed; a multi-channel map is drawn based on the detection data of the whole area; and according to the measured data, a full map of the apparent resistivity of the detection area is drawn to determine an abnormal area.

Description

technical field [0001] The invention relates to a method for transient electromagnetic detection of Japanese abandoned chemical weapons on land. Background technique [0002] At present, 60 Japanese ACW burial sites have been discovered in China, covering 19 provinces (regions), and there are as many as 1,241 cases with exact use time, location and injury records. A lot of manpower, material and financial resources have been invested in the disposal of these Japanese abandoned chemical shells and poisons. [0003] At present, the exact number of bombs in the Dunhua area of ​​Jilin Province and the Meihekou area of ​​Jilin Province are still to be further verified; and the areas where the bombs may be buried after preliminary investigations include Harbin, Acheng, Qiqihar, Heilongjiang Province, Hunchun, and Changchun in Jilin Province , Qiuligou and Malugou in the Dunhua area. [0004] Nowadays, the methods for detecting Japanese ACW on land mainly include magnetic method ...
