Definitions

  • This invention relates to a system and a method for improving security in the handling and use of blasting intermediates, commonly referred to as pumpable explosives.
  • Explosives are inherently dangerous products and security in the storage and handling of explosives has been a concern, especially as their use in mining and industry has increased since the invention of dynamite.
  • a series of new situations has arisen which place ever increasing demands on users of explosives to ensure that they are securely stored, handled and accounted for.
  • South Africa for example, large quantities of explosives are used in deep level mining environments as well as in open cast mining and in civil engineering projects.
  • the rise of a number of relatively new unlawful uses of explosives has produced a demand for tighter control on their use.
  • pirate mining of existing mines has become an increasing problem, both in South Africa and elsewhere.
  • the two liquids must, however, be separately transported from an explosives gel manufacturing facility and then loaded into separate tanks in the pumping unit for mixing and placement by the user into a blast hole. Since the separate components are harmless on their own, transport and security requirements for the separate gel components have been relaxed and the security focus has moved to the pumping unit in which the two gel components are present in close proximity for the first time in the blasting cycle. This has resulted in several different methods to prevent unauthorized use and operation of the pumping unit.
  • One solution has been to fit a conventional keyed lock to the pumping unit, which an authorized user can use to lock the pumping unit to prevent unauthorized use and operation of the pump.
  • the contents of the container may be accessible only through the access port of the container, the container being otherwise sealed, and the closable access port of the container may be enabled to open only if engaged with a charging or discharging means having a security device matching that of the container.
  • the container may have a unique identifier associated therewith.
  • the unique identifier may be a visible mark on the container or may be invisible to the naked eye.
  • Operation of the charging and/or discharging means may be enabled only if engaged with a container having a security device matching that of the charging or discharging means and may be otherwise disenabled.
  • the security devices of the container and the charging and/or discharging means may include complementary coupling devices on the container and the charging and/or discharging means, a first of which is located on the container at the port thereof and a second of which is located on the charging and/or discharging means, the devices, when coupled, being operable to permit the flow of contents to between the container and the charging and/or discharging means.
  • the complementary coupling devices may comprise a spigot on the container or the charging and/or discharging means and a socket on the other of the container or the charging and/or discharging means.
  • the coupling means may include pressure equalizing means for equalizing the pressure in the container with ambient pressure as the container is emptied or filled.
  • the pressure equalizing means may comprise an aperture controlled by a valve to permit the flow of air but restrict the flow of liquid contents of the container.
  • the container may be collapsible or may contain a collapsible bladder.
  • the security devices of the container and the charging and/or discharging means may include electronic signal communications means on the container and the charging and/or discharging means, the communications means of the container and the charging and/or discharging means being operable for signal communication therebetween.
  • the container and the charging and/or discharging means may include complementary signal interfaces.
  • the signal communication between the electronic signal communications means on the container and the charging and/or discharging means may be by means of a digital signal.
  • the signal may be communicated wirelessly.
  • the signal may be a Radio Frequency (RF) signal.
  • RF Radio Frequency
  • the security device of the container may include a unique identifier in the form of a digital code that is communicated by the signal communications means whenever the container is engaged with the charging means.
  • the discharging device may also include a unique identifier in the form of a digital code that is communicated by the signal communications means whenever the container is engaged with the discharging means.
  • the container may include a data storage means and the container may be operable to save at least the following information relating to each event in which a container is engaged with the discharging means:
  • the discharging means may also include a data storage means and the discharging means may be operable to save at least the following information relating to each event in which the container is engaged with the discharging means:
  • the charging means may include a data storage means and the charging means may be operable to save at least the following information relating to each event in which the container is engaged with the charging device:
  • the charging means may be operable to save the following additional information relating to each event in which the container is engaged with the charging device:
  • the charging means may be operable to download and save at least the following additional information:
  • the charging means may be operable to delete data from the data storage means of the container once that data has been downloaded to the data storage means of the charging means.
  • the discharging means may have a data storage means and the discharging means may be enabled only if the unique identifier of the container matches an identifier saved in the data storage means of the discharging means.
  • the charging means may be enabled only if the unique identifier of the container matches an identifier saved in the data storage means of the charging means.
  • the charging means may be operably connected to a computer data processing system, the data storage means of the charging means being accessible thereby.
  • the information communicated by the electronic signal communications means may be encrypted upon transmission and decrypted upon receipt.
  • Only a single container may have a security device that matches the security device of the charging and/or discharging means.
  • the security system comprises a system for distributing a two-part pumpable explosives gel for charging blast holes in a mine or other industry;
  • the container comprises a container for at least one of the components of the explosives gel;
  • the charging means comprises a filling station for filling containers with the at least one explosives gel component;
  • the discharging means comprises an explosives gel pump for charging blast holes with the explosives gel.
  • the at least one component many be activator component of the explosives gel.
  • the filling station may be operable to test the integrity of the container and its closure when the container is engaged with the pump and to suspend filling of the container if the integrity of the container is compromised and/or to record that the integrity of the container has been compromised.
  • the test may comprise a pressure test.
  • the one gel is called the activator or sensitizer, and the other the base emulsion/water-gel.
  • the activator or sensitizer Several different types of liquid explosives are available some of which require a delayed chemical reaction to activate after being mixed, while others are activated immediately after being brought together.
  • a conventional keyed lock (8) is fitted to the pumping unit (1) and an authorized user can use the key to lock the pumping unit (1) to prevent unauthorized use and operation of the pumping unit.
  • Figures 2 to 4 show different components comprising a security system for providing conditional access to contents of a container to prevent unauthorized use and operation of the pumping unit as well as access to the contents of the container.
  • the system uses what may be described as a "liquid key", in the form of a removable container (12), for one of the gels components.
  • this component is preferably the activator/ sensitizer.
  • the removable container (12) may contain either one or both of the two gel components or two separate removable containers could be used, one for each of the respective gel components.
  • the container (12) has a connector (13) for connecting the container (12) to a pumping unit (15) when the container (12) is engaged with the pumping unit (15).
  • the container (12) also has an electronic signal interface (14), which engages with a complementary interface (11) on the pumping unit (15).
  • the pumping unit (15) is designed so that when the container (12) is removed from the pumping unit (15) the pumping unit (15) is disabled and cannot produce a material that will perform as an explosive. In effect, the container (12) may be said to perform the function of a key.
  • the container (12) may be a rigid device having an internal collapsible bladder for its contents or the container (12) itself may be collapsible.
  • the container may include an pressure equalization device (not shown) for equalizing the pressure in the container (12) with ambient pressure as the container (12) is emptied or filled.
  • the pressure equalizing device may comprise an aperture controlled by a valve to permit the flow of air but restrict the flow of liquid contents of the container (12) or may be of any suitable design.
  • the pressure equalization device may comprise a part of the connector (13) of the container (12).
  • the connector (13) on the container (12) is a plug or spigot-like connector and is received into a complementary socket (19) on the pumping unit (15).
  • the spigot and socket (13,19) are of a special configuration and are designed in such a manner that it is difficult to connect a container (12) other than that containing the special spigot (13) to the pumping unit (15).
  • the spigot (13) incorporates a closure (not shown), which is only operable to open and then to close if the container (12) is engaged with a complementary socket (19).
  • the container is sealed and tampering with the container in an attempt to access to the contents of the container will be evident or will render the container transparent.
  • the design of the spigot (13) and socket (19) are not shown in detail and the design of such components will be within the ability of competent design engineers.
  • the container (12) and pumping unit (15) have engageable data interfaces (14,11) for the transmission and reception of data signals.
  • the signals are short range RF signals and are transmitted wirelessly. It will be appreciated that a wide variety of signal transmissions may also be used.
  • the container (12) has a signal generator incorporated in the interface (14), which transmits an encoded signal containing a unique identifier for the container (12). Such signal generators are relatively simple and inexpensive and are used in applications such as remote control devices for household equipment.
  • the pumping unit (15) has a receiver and decryption device incorporated in the interface (11).
  • the decryption device On receipt of an encoded signal from a container (12) interfaced with the pumping unit (15), the decryption device decrypts the encoded signal and obtains the unique identifier of the container (12).
  • the pumping unit (12) has a data storage device (20) and only if the unique identifier matches an identifier held in a memory (20) of the pumping unit (15) will it enable discharging of the contents of the container (12) and operation of the pumping unit (15) to produce an explosive.
  • the identification of the container (12) by the pumping unit in this manner is optional and in simplified systems, the pumping unit (15) may not have a memory device, but merely its own unique identifier, as described below.
  • the pumping unit may be operable to save the similar information as set out below in respect of the container, in relation to each event in which the container (12) is engaged with the pumping unit (15), ie the date of the event and time of the event, which may be provided by a system clock of the processor of the container (12) or a clock on the pumping unit (15) and the unique identifier of the container (12).
  • the number of operating cycles of the pumping unit (15) performed while engaged with the container (12) and the date and time of performance of those cycles during any event are recorded and stored.
  • modern pumping units (15) that are used for the pumping of explosives gels are capable of pumping the two components of the explosives gel to good levels of accuracy, both in terms of the relative masses or volumes of the two components with respect to one another and in terms of the total amounts of the combined components pumped in any one pumping cycle.
  • individual pumps are set to pump a predetermined mass or volume of explosive into a blast hole with each pumping cycle. For this reason, a knowledge of the identity of the pump (15) used and the number of times it has been activated will give a good idea of the actual amount of explosives gels consumed and used for blasting purposes.
  • Typical power supplies currently used are air pressure (compressed air), water pressure, or electrical devices and these sources of power may be interrupted.
  • any other functional aspect of the pumping unit (15) that would effectively prevent the pumping unit from creating limited amounts of a potentially explosive material may be disabled when the liquid container (12) is removed.
  • the liquid container (12) is designed to discourage unauthorized access to the liquid/gel contents of the container (12), or at least to make it technically difficult to gain unauthorized access to the contents of the container (12). This is achieved by manufacturing the container (12) as a sealed unit in respect of which tampering will be evident and ensuring that it is difficult to remove the contents of the container without the container (12) being connected to the pumping unit (15).
  • each of the removable liquid containers (12) has a unique identification number indelibly imprinted thereon and which is visible to the naked eye.
  • Other non-visible identifications may be used, such as indicia that are visible only under ultra-violet light. This number may or may not be the same as the unique identifier (RFID) embedded in the removable container (12).
  • RFID unique identifier
  • the container (12) has a data storage device (22) embedded therein and operably connected to the data interface (14) and to a processor (not shown).
  • the data storage device (22) is operable to store data relating to each event in which a container (12) is engaged with the pumping unit (15), such data including: the date of the event and time of the event, which may be provided by a system clock of the processor of the container (12) or a clock on the pumping unit (15) and the unique identifier of the pumping unit (15).
  • the number of operating cycles of the pumping unit (15) performed while engaged with the container during any event and the date and time of performance of those cycles during any event are recorded and stored.
  • This information is readily accessible and may be in the form of the number of times that the pumping unit (15) is activated and/or the number of pumping strokes performed by the pumping unit (15). This information will give a reliable indication of the amount of explosives actually pumped by that pumping unit (15) while coupled to the particular container (12).
  • An additional aspect the system using the liquid container key (12) comprises means to refill the container (12), comprising a refilling machine (21). Refilling may be performed manually or automatically. However, automated refilling has certain security advantages.
  • a refilling machine (21) is shown in Figure 4 and is operable to fill a container (12) with a preselected amount of liquid. In order to accurately audit the actual amount of liquid used, the refilling machine (21) is operable to measure the amount of liquid present in the container (12) before refilling it to achieve the preselected total amount. Alternatively, the container (12) may be filled to the predetermined total capacity required and the amount of the content needed to achieve this capacity recorded. This will allow the amount of liquid in the container (12) discharged since its last refilling to be calculated.
  • the net amount of liquid used from the container (12) can then be reconciled against the actual amount used in explosions on the mine.
  • the reconciliation process may be made even more robust by arranging for the refilling machine (21) to automatically detect the tank identification number by means of the RF-based identification system.
  • the refilling machine (21) is provided with its own communications interface (26), which is operably connected to a data storage device (27) of the refilling machine (21). Under the control of a processor (not shown) the refilling machine (21) is operable to download the unique identification number of the container (12).
  • the refilling machine (21) may be disenabled from operation if the unique identification number of the container (12) does not match an identification number stored on in the memory (27) of the refilling machine (21).
  • the closure of the container (12) will also not operate unless the spigot (13) of the container (12) engages with a socket (19) of the refilling machine (21).
  • the refilling machine is programmed to interrogate the memory (22) of the container (12) and to download information, which may include, in respect of each event on which the container (12) is engaged with the refilling machine (21), the date of the event and time of the event, which may be provide by a system clock (not shown) of the container (12) or the refilling machine (21), the unique identifier of the container, and the amount of contents remaining in the container (12) or the amount of contents required to fill the container (12) to capacity.
  • the refilling machine (21) may download information saved on the data storage means (22) of the container (12) relating to previous events in which it was engaged with the pumping unit (15).
  • the refilling unit may delete data from the data storage device (22) of the container (12) once that data has been downloaded to the data storage device (27) of the refilling machine (21).
  • the processor and data storage device (27) of the refilling machine (21) may be accessed by a data management system (not shown), as indicated at (28), which may accumulate and process all of the data saved to the data storage device (27) of the refilling machine (21).
  • the refilling machine (21) may be operable to check the integrity of each and every liquid container (12) before it is refilled. This may be achieved by means of an automated pressure test. If implemented, a responsible person may be notified whenever the security of the liquid inside the liquid container (12) has been compromised. Typically the security of the liquid inside the container could be compromised by a hole in the container (12) or any other damage to the components of the container (12). In addition, the refilling machine (21) is inactivated if the integrity of the container (12) is compromised and it will not charge the container (12) with content.
  • the refilling machine (21) is designed for automated filling of containers (12) without any human intervention or human contact with the liquid that is being loaded into the liquid container key (12).
  • a refilling machine (21) will significantly improve security and the chances of the liquid activator landing in the wrong hands.
  • the refilling machine (21) should be centrally located in a secure and well-controlled and audited environment, indicated at (24).
