Abstract

A mining shovel with compositional sensors comprises a bucket having various inward looking sensors positioned throughout the bucket. The bucket can also have disposed thereon a control enclosure that houses processing equipment that receives and analyzes the data collected by the inward looking sensors. The mining shovel with compositional sensors can be used as part of a system to manage a mining field, including generating and transmitting instructions directing where to deposit material located in the bucket based on the data collected from the inward looking sensors positioned in the bucket.

Claims

1. A mining shovel bucket comprising:

a first side wall;

a second side wall opposite the first side wall;

an upper wall portion;

a first in-cheek sensor positioned on the first side wall and facing towards the second side wall and configured to collect data related to the chemical composition of material contained within the bucket;

at least one down-looking sensor positioned on the upper wall portion and facing an interior of the mining shovel bucket and configured to collect data related to the chemical composition of material contained within the bucket;

a control enclosure mounted relative to the mining shovel bucket; and

a signal processing system housed within the control enclosure and configured to receive the data related to the chemical composition of material contained within the bucket collected by the first in-cheek sensor and the at least one down-looking sensor and at least partially process the data such that the chemical composition of the material is determined locally by the signal processing system.

2. The mining shovel bucket of claim 1, wherein the bucket comprises a first down-looking sensor positioned in a forward portion of the upper wall portion and a second down-looking sensor positioned in an aft portion of the upper wall portion.

3. The mining shovel bucket of claim 1, wherein the control enclosure further houses a power supply for the first in-cheek sensor, the at least one down-looking sensor, and the signal processing system.

4. The mining shovel bucket of claim 1, wherein the control enclosure further houses a communications system configured to transmit information generated by the signal processing system to a location remote from the mining shovel bucket.

5. The mining shovel bucket of claim 1, wherein the at least one down-looking sensor is a different type of sensor from the first in-cheek sensor.

9. The mining shovel bucket of claim 4, wherein the communications system is configured to transmit chemical composition information to a fleet management system located remote from the mining shovel bucket.

10. The mining shovel bucket of claim 4, wherein the communications system is configured to transmit chemical composition information to a display located in a chassis of a mining shovel to which the mining shovel bucket is attached.

11. The mining shovel bucket of claim 1, further comprising a second in-cheek sensor positioned on the second side wall and facing towards the first side wall.

12. The mining shovel bucket of claim 1, wherein at least one of the first in-cheek sensor and the at least one down-looking sensor have formed thereon a ruggedized, nonmetallic layer.

13. The mining shovel bucket of claim 1, wherein the first in-cheek sensor is selected from one of a radiometric sensor, a photometric sensor, and an electromagnetic sensor.

14. The mining shovel bucket of claim 1, wherein the at least one down-looking sensor is selected from one of a radiometric sensor, a photometric sensor, and an electromagnetic sensor.

6. A method of classifying and sorting mining material comprising:

collecting data related to the chemical composition of material contained within a mining shovel bucket by sensing mining material loaded in the mining shovel bucket using at least one in-cheek sensor mounted on a side wall of the mining shovel bucket and at least one down-looking sensor mounted on a top wall portion of the mining shovel bucket;

processing the data related to the chemical composition of material contained within the mining shovel bucket using a signal processing system housed within a control housing mounted relative to the mining shovel bucket to thereby identify the composition of the mining material locally at the signal processing system; and

providing an output signal to indicate depositing the mining material in a specific location based on the composition of the mining material.

7. The method of claim 6, wherein processing the data related to the chemical composition of material contained within the mining shovel comprises:

transmitting the data to an analogue to digital signal converter to convert the data to a digital signal;

performing Fourier Analysis on the digital signal to generate arbitrary power spectra data;

comparing the arbitrary power spectra data to known power spectra to identify pattern matching between the arbitrary power spectra and known power spectra; and

identifying the composition of the mineral material when a sufficient pattern match is identified between the arbitrary power spectra and a known power spectra associated with a known material.

8. The method of claim 7, wherein the arbitrary power spectra is of amplitude/frequency or amplitude/wavelength.

15. The method of claim 6, further comprising:

transmitting the composition of the mining material to a display located in a chassis of a mining shovel to which the mining shovel bucket is attached.

16. The method of claim 15, wherein depositing the mining material in a specific location based on the composition of the mining material comprises an operator operating the mining shovel bucket to thereby deposit the mining material in a specific location based on the composition of the mining material displayed on the display.

17. The method of claim 6, further comprising:

transmitting the composition of the mining material to a fleet management system located remote from the mining shovel bucket.

18. The method of claim 17, wherein depositing the mining material in a specific location based on the composition of the mining material comprises an operator of the mining shovel bucket receiving from the fleet management system the specific location where the mining material is to be deposited.

19. The method of claim 6, wherein the at least one down-looking sensor is a different type of sensor from the first in-cheek sensor.

20. The method of claim 6, wherein depositing the mining material in a specific location based on the composition of the mining material takes into account the real time value of the composition of the mining material.
