Solutions package
Hard-Rock Drill and Blast Package
For civil contractors running hard-rock road tunnels and hydropower headrace and tailrace tunnels. The package equips the full drill-and-blast round: a DGZ multi-function rig for probe-ahead and forepoling, a ZJS intelligent grouting plant for water-stop and consolidation works, a hydraulic face jumbo with a drilling-and-splitting alternative for vibration-restricted faces, a mechanised charge-up rig, an intelligent tunnelling excavator for mucking and scaling, primary support with bolts, arches and shotcrete, and a horizontal rescue drilling rig. An HZS modular batching plant and slag crushing line support on-site aggregate production. A waterproofing, secondary-lining and invert-formwork train is included for sections that require a full CIP final lining.

Scope of supply
Probe-ahead and pre-support drilling
Probing ahead of the face on long hard-rock drives manages fault-zone, water-inflow and ground-class-transition risk. The DGZ multi-function rig handles advance drilling, MWD coring and forepoling from one chassis.
Pre-injection and consolidation grouting
Probe-ahead is followed by water-stop or consolidation grouting before advancing through fault zones or water-bearing ground. The ZJS plant integrates storage, mixing, pumping and data logging on one platform.
Face advance method
ZYS multi-boom hydraulic jumbo on a cable-tethered electric chassis is the civil-side default; ZP drilling-and-splitting substitutes where vibration limits rule out blasting. CYTJ45 single-boom and CYTJ45/2 twin-boom diesel-tramming jumbos cover mining-civil headings sharing the contract, with the CYTJ45/2(Z) variant adding scanner-driven face capture and automated drilling.
Tunnel Excavation & Support
Tunnel Drilling jumbo
ZYS multi-boom hydraulic face jumbo with integrated positioning and scanning for civil tunnels.
Tunnel Excavation & Support
Drilling and splitting jumbo
ZP non-blast substitute for vibration-restricted portals, urban approaches and stub headings.
Mining
CYTJ45/2 Twin-Boom Mining Drilling Jumbo
CYTJ45/2 twin-boom development jumbo for mining-civil headings; CYTJ45/2(Z) intelligent variant adds automated drill-pattern execution and scanner-driven face capture.
Mining
CYTJ45 Single-Boom Mining Drilling Jumbo
CYTJ45 single-boom hydraulic development jumbo for tighter decline and roadway face drilling.
Mechanised charge-up
Mechanised charging cuts powder-factor variance and pulls crews back from the face. The RHZ tunnel platform is the civil unit; the mining RHZ vehicle suits adjacent mining-civil drives with higher duty cycles.
Mucking, scaling and at-height work
The intelligent tunnelling excavator combines mucking, scaling, profile correction and dust suppression. The digital digging-and-loading machine handles smaller sections. The DZP131 platform takes crewed at-height tasks off the critical path. The WJ-6 LHD adds a load-tram-dump option for mining-civil drives running drawpoint-style mucking on the same contract.
Tunnel Excavation & Support
Intelligent Tunnelling Excavator
Combined mucking, scaling, profile correction and dust suppression on a single chassis.
Tunnel Excavation & Support
Digital digging and loading machine
Small-section mucking and breaking for shafts, culverts and stub headings.
Tunnel Excavation & Support
Tunnel Multi-Process Operation Platform Vehicle
DZP131 multi-process platform for at-height services, ventilation, charging support and survey setouts.
Mining
WJ-6 Underground Diesel LHD
WJ-6 underground diesel LHD for mining-civil drives running drawpoint muck handling on 4.5 m by 4.5 m sections.
Primary support: bolts and steel arches
The MT bolting jumbo runs civil systematic and lock-foot bolting. The CYTM41/2(A) mining bolt-drilling jumbo covers narrower mining-civil drives. SCD steel-arch trolleys and mining arch-frame trolleys handle arch erection. FRP bolts suit corrosive or non-conductive ground.
Tunnel Excavation & Support
Bolting Jumbo
MT civil bolting jumbo for systematic and lock-foot bolts with optional one-key drill-and-bolt.
Mining
CYTM41/2(A) Mining Bolt-Drilling Jumbo
CYTM41/2(A) mining bolt-drilling jumbo for one-pass drilling, mesh and bolt installation on narrower mining-civil drives.
Tunnel Excavation & Support
Steel arch frame trolley
SCD steel-arch trolley for arch erection in poor ground on civil headings.
Mining
Mining Arch-Frame Trolley
Mining arch-frame trolley for U-set installation in underground drives.
FRP & Composite Materials
Fiber Reinforced Composite Bolts
FRP rock bolts for corrosion-resistant, non-conductive and no-spark applications.
Shotcrete and on-site batching
Wet-mix shotcrete is the primary lining behind the face. The HPS shotcrete jumbo runs civil tunnels with intelligent spray-path planning. The UPS-20J(B) suits narrower mining-civil drives. The HZS modular batching plant supports remote alignments.
Tunnel Excavation & Support
Shotcrete Jumbo
HPS wet-mix shotcrete jumbo with intelligent spray-path planning and automatic spraying.
Mining
UPS-20J(B) Mining Shotcrete Machine
UPS-20J(B) mining-grade shotcrete machine for narrower mining-civil drives.
Concrete, Aggregates & Recycling
HZS Modular Concrete Batching Plant
HZS modular concrete batching plant for shotcrete and lining concrete on remote sites.
Spoil handling and slag-to-aggregate
The DG, DY and DL slag crushing lines turn excavated rock into graded crushed stone and manufactured sand for shotcrete, lining concrete and surface works. Conveyor variants cover adit, transfer, single-heading and shaft duties. The UK-40 underground mining truck is the alternative on mining-civil drives that haul muck on rubber rather than belt, sized for 5.5 m by 5.5 m lane sections.

Lining train: waterproofing, secondary lining and invert
Hard-rock road tunnels typically receive a full cast-in-place secondary lining with waterproof membrane. The FSG12, CQS, YHS12 and YDZQ gantries cover membrane laying, lining placement, controlled curing and parallel invert pours.

Inverted arch bridge formwork
YDZQ self-propelled invert trestle and formwork for parallel invert pours.
Lining quality acceptance
Road-tunnel acceptance includes radar-based verification of lining thickness, density and reinforcement before track-bed or pavement works. The CQJ10 carries a multi-channel radar array for synchronous full-section measurement.
Air quality and ventilation
Post-blast air quality drives cycle time on long single-heading tunnels. The plateau-type tunnel dust collector is a mobile extraction unit with self-cleaning cluster filters, sized for face air quality.
Emergency rescue
Horizontal rescue drilling rig opens an escape passage in collapse events on a hard-rock heading. The DJZ800-ND variant is configured for transport-infrastructure work; the ZYL-580/800S full-hydraulic variant suits coal mining.
Engineering and R&D
CRCHI Australia brings full OEM engineering and R&D capacity to every package. Most catalogue equipment is configurable to project requirements; project-specific scope is engineered to brief; and where a project calls for it, a complete solution is developed from the ground up. Typical tailoring on hard-rock D&B drives includes face-jumbo boom configuration, charging-rig hose runs, shotcrete reach, lining-gantry geometry and slag-line throughput matched to the drive.
