Definitions
- the hose drive assembly may further comprise a detonator tube into which a detonator can be loaded for transport to the blast hole.
- the detonator tube can further include a platform that can be pivoted between a support position and a release position.
- the hose drive assembly may further comprise one or more string tubes through which a string attached to the detonator can be passed.
- two string tubes are provided, and the hose drive assembly further comprises a cutter for cutting the string between the string tubes.
- the charge delivery module may further comprise one or more hose carriers attached to the boom for restraining the hose.
- The, or each, carrier can include a pair of rollers between which the hose can be retained.
- the magazine can have capacity to hold twenty marking blocks.
- the present invention also relates to a method of charging a blast hole using a charge delivery module having a hose, a hose reel assembly attached to a vehicle and having a reel on which the hose can be wound, and a hose drive assembly attached to an outer end of a boom extending from the vehicle, the method including:
- Figure 2 is a top view of the charge delivery module and support vehicle of
- Figure 1 Figure 3: is an enlarged view of a hose carriers and snubber wheel of the charge delivery module of Figure 1 ;
- the snubber wheel 120 is mounted on a pivotable support arm 124 that forms part of the frame 1 19.
- a turnbuckle 125 restrains the support arm 124 and allows adjustment to a desired inclination.
- the final guide wheel 122 is supported on the frame 1 19.
- a roller 126 is also mounted on the support arm 124.
- the snubber wheel 120, roller 126 and support arm 124 define a throughway through which the hose 102 can pass, and together prevent the hose 102 from dislodging from the snubber wheel 120.
- a detonator platform 134 is provided within the detonator tube 128.
- the detonator platform 134 is illustrated in Figure 9.
- the platform 134 is arranged to pivot on a pin 136, between a support position P-i - in which the platform extends transversely across the tube 128 to block passage of the detonator down the tube - and a release position P 2 .
- the support position of the platform 134 is shown in light lines, and the release position is shown in dark lines. When the platform 134 is in the release position, the detonator can pass downwardly through the tube for delivery into the blast hole.
- a camera may be provided on the hose drive assembly 106 that, together with a display provided to the operator of the support vehicle 10, enables the operator to quickly and accurately align the hose drive assembly 106 over a blast hole.
- the boom 14 is extendible and retractable to increase the reach of the boom depending on the relative position of the blast holes to the vehicle 10.
- the length of the boom 14 is adjustable via any suitable actuator 173, such as hydraulic, or a gear meshing with teeth.
- the controller 171 can operate the first and/or second motors 1 14, 1 18 to payout or retrieve hose 102 from the reel 108 to allow for changes in length of the boom 14 and maintain the hose 102 in a linear arrangement along the length of the boom 14.
- a slewing telehandler is a particularly suitable support vehicle.
- the slewing telehandlers sold by the Merlo Company under the trade name Roto can be used.
- a slewing telehandler has a slewing turret on which the operator's cabin and the boom are mounted.
- the boom is telescopic, in some cases to a maximum length of approximately 16 metres.
- Figure 10 shows schematically in plan view a typical blast site B beside a sloped wall W within an open pit mine. As will be appreciated, risk of injury/damage decreases with distance from the base of the wall W. In Figure 10, the location of blast holes are indicated by dark circles.
- Figures 1 1 and 12 show a stemming module 200 of a system for charging a blast hole according to an embodiment of the present invention.
- the stemming module 200 is to be mounted on a support vehicle 10.
- the stemming module 200 can be mounted on the outer end of the boom 14 of the support vehicle 10.
- the stemming module 200 has mounts 210a, 210b that co-operate with like mounting points on the boom 14 of the support vehicle 10 to mount the stemming module 200 on the end of the boom 14.
- the marking module 300 has mounts that co-operate with like mounting points on the boom 14 of the support vehicle 10 to mount the marking module 300 on the end of the boom 14.
- the detonator Prior to pumping liquid explosive material into the blast hole, the detonator is to be located in blast hole. To this end, the detonator is placed on the platform 134 in detonator tube 128 by passing the detonator through the opening 132. When the detonator tube 128 is located over the blast hole, the platform 134 is pivoted to the release position, which releases the detonator for lowering into the blast hole.
- the string is passed through the string tubes 140a, 140b and eyelet 142, and passed through the slit 130. Once the detonator has been released, an operator lowers the detonator on the string into position. The hose 102 can then be positioned in the blast hole for delivery of the liquid explosive material into the blast hole.
- the leads of all blast holes can be tied in and the blast site readied for firing.
- the boom may be pivotally mounted about an axis lateral to the vertical so that the boom can be moved upward and downward relative to the vehicle.
