The invention claimed is: 1. A method of logging use of a non-electric detonator, which comprises recording identity data associated with the detonator at the time the detonator is being loaded in a blasthole, recording consumption of the detonator, and relating the identity data associated with the detonator to an inventory of non-electric detonators thereby allowing the inventory to be updated, wherein the identity data associated with the non-electric detonator are recorded using an electronic device, wherein the identity data associated with the non-electric detonator are recorded immediately before the detonator is loaded in the blasthole. 2. A method according to claim 1, wherein the non-electric detonator is a shock tube detonator. 3. A method according to claim 1 or 2, wherein the identity data takes the form of a bar code provided on an external surface of the detonator, or on a tag attached to or associated with the detonator, and the electronic device used for recording the identity data is a hand held bar code reader. 4. A method according to claim 1 or 2, wherein identity data for the non-electric detonator are stored in a radio frequency identification (RFID) tag associated with the detonator, and the electronic device for recording the identity data is a radio frequency reader for the tag. 5. A method according to claim 1, wherein a number of non-electric detonators are employed, each detonator having associated identity data that are unique to each detonator, and wherein the electronic device maintains a record of each detonator as an individual and unique record entry. 6. A method according to claim 1, wherein a number of non-electric detonators are employed, the identity data being the same for each detonator, and wherein the electronic device used for reading the identity data functions as an electronic counter for each detonator. 7. A method according to claim 1, wherein loading of the blasthole is completed as soon as possible after the identity data of the detonator have been recorded and the detonator loaded in the blasthole. 8. A method according to claim 1, wherein consumption of the non-electric detonator is recorded electronically by recording detonation of another detonator loaded in the same blasthole. 9. A method according to claim 8, wherein detonation of the another detonator is used to initiate detonation of the non-electric detonator. 10. A method according to claim 8 or 9, wherein the another detonator is a programmable electronic detonator that itself has identity data associated with it and that is able to report electronically to a blast controller a ready-to-fire signal immediately prior to detonation. 11. A method according to claim 8 or 9, wherein the another detonator is an electric detonator and actual detonation of the electric detonator is recorded based on measurements of firing circuit resistance. 12. A method according to claim 1, wherein consumption of the non-electric detonator is recorded electronically based on operation of a remote firing system for the non-electric detonator. 13. A method according to claim 1, wherein the inventory is updated subsequent to loading of the non-electric detonator in a blasthole during blast preparation. 14. A method according to claim 1, wherein the inventory is updated subsequent to detonator consumption. 15. A method according to claim 1, wherein the electronic device used to record the identity data associated with the non-electric detonator is configured to interface as necessary with system components that are used for data management. 16. A method according to claim 1, wherein data recorded by the electronic device are automatically transmitted to a remote data management system, where the data can be reconciled against an inventory of non-electric detonators. 17. A method according to claim 16, wherein data relating to consumption of the non-electric detonator are also recorded and these data are also transmitted automatically to the data management system.
