Embodiment 1

[0023] Embodiment 1 (the detonation pressure of setting detection is 1Mp)

[0024] 1. Use a high-pressure pipe, one end is connected to the high-pressure pipe connection port 5 on the rear end cover of the special detection device, and the other end is connected to the pressure gauge 7;

[0025] 2. Use another high-pressure pipe to connect the inflation nozzle 4 of the special detection device with the air compressor;

[0026] 3. Connect the sample to be inspected to the detonator and the detonator line 6, place it in the cavity 1 of the detection device, close the pressure valve 3 and seal the detection device;

[0027] 4. Use an air compressor for long-distance pressurization. When the pressure reaches 1Mp, keep it for 3 minutes before detonating;

[0028] 5. Check whether the sample is detonated completely.

Embodiment 2

[0029] Embodiment 2 (the detonation pressure of setting detection is 1.5Mp)

[0030] 1. Use a high-pressure pipe, one end is connected to the high-pressure pipe connection port 5 on the rear end cover of the special detection device, and the other end is connected to the pressure gauge 7;

[0031] 2. Use another high-pressure pipe to connect the inflation nozzle 4 of the special detection device with the air compressor;

[0032] 3. Connect the sample to be inspected with a detonator, connect it to the detonator line 6 and place it in the cavity 1 of the detection device, close the pressure valve 3 and seal the detection device;

[0033] 4. Use an air compressor for long-distance pressurization. When the pressure reaches 1.5Mp, keep it for 5 minutes before detonating;

[0034] 5. Check whether the sample is detonated completely.

Abstract

The invention relates to a method and device for detecting the sensitivity to primary explosion of an emulsion explosive and a seismic explosive column under a pressure-bearing state. The method comprises the steps of: respectively connecting a pressure meter with a special detection device and connecting a charging connector of the special detection device with an air compressor through high-pressure pipes; placing a sample to be detected in a special closed detection device; remotely pressurizing to reach the required pressure, keeping for 3-5min and then primarily exploding; and checking whether the sample is completely primarily exploded. The device is provided with a cavity, the inner front end of the cavity is provided with a pressure valve, and a charging connector used for being connected with the air compressor, a high-pressure pipe port used for being connected with the pressure meter and a detonator wire are respectively arranged on a rear end cover of the cavity. Through applying pressure remotely and monitoring remotely, when reaching the set pressure, the emulsion explosive and the seismic explosive column are primarily exploded, thus the device is used for safely, reliably, accurately and conveniently detecting the sensitivity to safe primary explosion and the critical pressure of the explosive under the pressure-bearing state. The special detection device has the advantages of simple structure, low cost and convenience for use.

Description

technical field [0001] The invention relates to civil explosive materials, in particular to a detection method and a special detection device for the detonation sensitivity of an emulsion explosive and a seismic source charge column under pressure. Background technique [0002] Existing detonation sensitivity detection of emulsion explosives and seismic source charges is carried out under normal pressure, but in actual use, especially when detonating in water, it is carried out under pressure, and there is currently no method for detonation The detonation sensitivity of emulsion explosives and seismic source charges under pressure is tested. Contents of the invention [0003] The technical problem to be solved by the present invention is to study the detonation sensitivity under pressure, and provide a safe, reliable, accurate and convenient method for detecting the detonation sensitivity and critical pressure of emulsion explosives and source charges under pressure. The ...
