Mining Chargeup Jumbo
UDK-40 Long-Hole Chargeup Jumbo
Mechanised long-hole explosives chargeup jumbo for underground non-coal production blasting. The UDK-40 mixes emulsion explosive on board from non-detonator-sensitive substrate and pumps it into pre-drilled long holes through a powered hose reel at up to 70 kg/min, with the charging operator working the boom by wireless remote control from a separate position on the heading. A 2000 kg on-board tank, 70 kg/min charging rate and 40 m maximum hole depth size the machine for sublevel-stoping rings and other production-cycle long-hole patterns drilled by a separate production-drill rig. The articulated four-wheel-drive chassis runs on a Yuchai 81 kW diesel; the boom carries a powered hole-pairing mechanism that aligns the charging tube to the borehole collar without manual hole-stabbing, with an optional pipe-shaking motor for misaligned or blind holes. Standard equipment includes a FOPS/ROPS certified canopy cab with reversing camera and 300 mm cab lift travel, and on-board informatisation for charge-record generation and remote monitoring. An optional screw-compressor air supply for borehole cleaning is available. Only two operators are needed on the face: one running the wireless remote, one assisting. Operating section range is 3 x 3 m up to 5 x 6 m, sized for production drives rather than development face advance. The UDK-40 is a production-cycle machine: it charges the long-hole rings drilled for sublevel stoping. Civil drill-and-blast tunnelling has no long-hole production counterpart, so RHZ is not a like-for-like equivalent. Pair the UDK-40 with the UC-0.4B for development-side face charging; the Chargeup Rig family covers the same face-charging task on civil tunnels.
Features
Long-hole bulk-emulsion charging at production rates. The plunger-pump charging system mixes substrate and pumps the finished emulsion at up to 70 kg/min into holes up to 40 m deep, with over-pressure, over-temperature and material-breakage alarms that trigger automatic shutdown. The 2000 kg on-board tank carries enough product for multiple sublevel-stoping rings without trip-out, and the site-mixed emulsion is non-detonator-sensitive, so charging plant and finished explosive only meet at the borehole.
Mechanised hole-pairing function. A powered hole-pairing mechanism on the boom head drives the charging tube longitudinally and rotationally under wireless remote control, aligning the charging tube to the borehole collar without manual hole-stabbing. This is the step that otherwise slows down long-hole production charging, particularly on up-holes and blind ring holes where the collar is above the operator's line of sight.
Optional pipe-shaking function for misaligned or blind holes. When fitted, an optional pipe-shaking motor oscillates the charging tube through a misaligned, irregular or partly-collapsed long hole, working it through the obstruction without forcing the tube or breaking out a manual rod-and-push step. Long ring holes shift over the days between drilling and charging, so this matters on production-cycle work.
Powered explosive feeding pipe reel for long holes. The reel drives the charging tube into the hole and retracts it after the charge is placed, providing tractive force for 40 m holes and reducing tube wear from manual hauling. An optional on-board screw compressor (12.5 kW, 1.8 m3/min at 8 bar) clears blocked holes with compressed air at the same setup when fitted, so a separate face compressor is not required.
Two-operator face crew with wireless remote control. One operator runs the charging cycle from the wireless remote, the second assists at the machine. Keeping the operator out of the immediate charge zone is one of the main safety hand-offs from a hand-charging cycle.
Articulated four-wheel-drive chassis with FOPS/ROPS canopy cab and on-board informatisation. Articulated chassis on 12.00R20 tyres with hydrodynamic transmission, wet axle, parking and service brakes; FOPS/ROPS-certified canopy cab with reversing camera and 300 mm cab lift travel. Automatic logging of charge weight, hole depth and equipment data with table-format charge-record generation and on-board fault alarming; optional construction-data download by USB or wireless and optional remote real-time monitoring.

Overview
Applications
Mechanised bulk-emulsion charging in underground non-coal production blasting, sized for sublevel-stoping rings and other long-hole production patterns drilled by a separate production-drill rig. Hole depth up to 40 m and a 2000 kg on-board tank support multiple-ring charging without trip-out; operating section range 3 x 3 m up to 5 x 6 m suits production drives rather than wider development drifts. Suited to operators converting a hand-charging long-hole cycle to a mechanised one on the production side of the mine, where 70 kg/min loading rate, a two-person face crew and powered hole-pairing replace the manual loading and hole-stabbing tasks. Pairs with the UC-0.4B on the development side, which covers face-advance charging with a basket platform; on the production side the UDK-40 covers ring-hole charging from the boom.
Performance
12 t empty and 14 t full on an 8800 x 1970 x 2300 mm transport envelope. 2000 kg on-board emulsion tank, charging rate 70 kg/min, substrate feeding speed 5 to 25 m/min, charging tube inner / outer diameter 25 / 32 mm. Maximum hole depth 40 m. Maximum working height 6 m, operating section range 3 x 3 m up to 5 x 6 m. Yuchai 81 kW diesel with a 120 L tank. Maximum travelling speed 17 km/h, maximum gradeability 25 %, minimum turning radius 3 m inner / 5.6 m outer. Approach / departure angle 14 / 14 degrees. Adaptation to altitude at or below 2000 m (high-altitude module optional). Local plus wireless remote control. Minimum gallery cross-section 2000 mm wide x 2500 mm high with the machine folded for transport; 5500 x 6700 mm work envelope with the boom extended; turning radii R3000 / R5600 with a 40 degree articulated steering angle.
Functions
Plunger-pump charging system with 2000 kg substrate tank, 70 kg/min charging rate, 5 to 25 m/min substrate feed and over-pressure / over-temperature / material-breakage alarms. Powered explosive-feeding pipe reel for long-hole feed and retract on hole depths to 40 m. Mechanised hole-pairing mechanism on the boom head with minus 90 to plus 90 degree slew and 0 to 105 degree adjustment angle; an optional pipe-shaking motor handles misaligned and blind holes when fitted. Optional on-board screw-compressor air supply for borehole cleaning. FOPS/ROPS-certified canopy cab with reversing camera and 300 mm cab lift travel. Articulated four-wheel-drive chassis on 12.00R20 tyres with wet axle, parking and service brakes. Electrical system at 380 V / 50 Hz standard with 1000 V / 50 Hz optional; engine provides working and travelling power so no shore-power supply is required. Informatisation covering construction-log analysis and table-format charge-record generation, USB or wireless construction-data download, fault alarming and optional remote real-time monitoring.
Benefits
Replaces a hand-charging long-hole crew with a two-person mechanised cycle running at 70 kg/min, 2.8 times the UC-0.4B development-cycle rate, on a 2000 kg tank that holds five times the substrate. Mechanised hole-pairing removes the manual hole-stabbing step that otherwise slows down long ring-hole charging, and the optional pipe-shaking motor, when fitted, works the tube through misaligned or blind holes without forcing it. Site-mixed non-detonator-sensitive emulsion keeps charging plant and finished explosive separate until the borehole, with on-board fault alarms shutting the cycle down on over-pressure, over-temperature or material breakage. An optional on-board screw compressor handles borehole cleaning at the same setup when fitted, and the wireless remote keeps the operator out of the immediate charge zone. Charge-record generation and optional remote monitoring give the shift a per-ring audit trail. CRCHI Australia handles commissioning, spares and aftermarket nationally.
