Abstract

Disclosed is a system for detonating a buried explosive device by discharging an electric discharge with at least five joules of energy to detonate the buried explosive device.

Claims

1. A method of detonating an explosive device that includes a blasting cap, the blasting cap including a metallic casing and a lead wire, the method comprising the steps of:

in a device, generating a high voltage electrical potential of at least thirty thousand volts having at least five joules of energy; and

discharging the high voltage electrical potential as an electric discharge into the earth, wherein the current path to ground of the electric discharge includes at least one item selected from the group consisting of;

the lead wire and the metallic casing to generate a discharge spark inside of the blasting cap between the metallic casing and the lead wire, whereby the blasting cap detonates the explosive device.

2. The method of claim 1, further comprising moving an electrode over the earth and discharging the high voltage electrical potential through the electrode.

3. The method of claim 1, further comprising pulsing the electric discharge.

4. The method of claim 3, wherein the pulsed electric discharge has a pulse duration between thirty and one hundred microseconds.

5. The method of claim 4, further comprising moving an electrode over the earth and discharging the high voltage electrical potential through the electrode.

6. The method of claim 1, wherein the device includes a Marx generator and wherein the method further comprises charging the Marx generator;

and

discharging the Marx generator to generate the high voltage electrical potential.

7. The method of claim 6, further comprising charging the Marx generator from an electrical potential stored in a battery.

8. The method of claim 6, further comprising initiating the discharge from the Marx generator with a solid state switch.

9. The method of claim 1, further comprising discharging the high voltage electrical potential from the device through an emitter having a substantially constant discharge point.

10. A method of locating and detonating a hidden explosive device, the method comprising:

in a device, generating a high voltage electrical potential of at least thirty thousand volts having at least five joules of energy;

moving an electrode over the earth; and

discharging the high voltage electrical potential into the earth through the electrode as an electric discharge, wherein the electric discharge occurs proximate to a conductor conductively connected to one item selected from the group consisting of;

a blasting cap lead wire and a metallic casing of the explosive device, wherein the electric discharge generates an electric arc inside of the explosive device that detonates the explosive device.

11. The method of claim 10, further comprising charging a Marx generator;

and

discharging the Marx generator to generate the high voltage electrical potential.

12. The method of claim 11, further comprising charging the Marx generator from an electrical potential stored in a battery.

13. The method of claim 10, further comprising pulsing the electric discharge.

14. The method of claim 13, wherein the pulsed electric discharge has a pulse duration between thirty and one hundred microseconds.

15. A method of locating and detonating a hidden explosive device that includes a lead wire conductively coupled to a blasting cap, the method comprising the steps of:

in a device, generating a high voltage electrical potential of at least thirty thousand volts having at least five joules of energy; and

discharging the high voltage electrical potential into the earth as a pulsed electric discharge with a pulse duration between thirty and one hundred microseconds, wherein the electric discharge occurs proximate to the lead wire, wherein the electric discharge generates an electric arc inside of the explosive device.

16. The method of claim 15, further comprising moving an electrode over the earth and discharging the high voltage electrical potential through the electrode.

17. The method of claim 15, further comprising charging a Marx generator;

and

discharging the Marx generator to generate the high voltage electrical potential.

18. The method of claim 15, wherein the electric arc detonates the explosive device.

19. The method of claim 15, further comprising discharging the high voltage electrical potential from the device through an emitter having a substantially constant discharge point.
