What is an underground tunneling jumbo?
A tunneling jumbo (drill jumbo) is the machine that mechanises the drill-and-blast cycle at an underground face: it trams to the face, positions its boom and feed beam against the rock, and drills the full blast-hole pattern accurately and quickly, replacing hand-held drilling with a controlled, repeatable pattern. Face size, drifter power and positioning accuracy decide development advance rates.
The FULONGZUAN CYLJY45 is a compact full-face tunneling jumbo built for drill-and-blast development in confined headings. Its defining choices are operator distance and adaptability: the jumbo is fully remote-controlled, its folding two-stage feed beam is designed for narrow, tight-bend roadways, and the buyer can specify full-diesel, diesel-electric hybrid or full-electric power against the mine's infrastructure.

Main Features
The CYLJY45's design answers the three constraints of small-section development. Space: the folding two-stage feed beam folds for tramming through tight bends yet opens to cover the full face. Control quality: a Danfoss industrial controller runs full electric proportional control, so boom movements are smooth and repeatable rather than on-off hydraulic. Safety: full remote control takes the operator away from the unsupported face during drilling — the same remove-the-person philosophy that runs across the FULONGZUAN mining range.

Frequently Asked Questions
What power option should a mine choose for a tunneling jumbo?
Match the mine's infrastructure: full diesel for headings without electrical supply, full electric where power and ventilation favour zero face emissions, hybrid where the jumbo must tram on diesel but drill on electric. The CYLJY45 is offered in all three.
Why does remote control matter on a drill jumbo?
The face is the highest-risk zone in development — fresh blasting ground, scaling and ventilation limits. Full remote control lets the operator drill the pattern from a safer position while keeping proportional boom control.
What size headings suit the CYLJY45?
It is a compact full-face jumbo positioned for confined and narrow headings, with a folding two-stage feed beam made for tight-bend roadways. Share your heading dimensions with the trade desk to confirm face coverage.
Conclusion
A tunneling jumbo turns hand drilling into a mechanised, remote, repeatable face cycle. For narrow-heading drill-and-blast work, the CYLJY45's three power options and folding feed beam are the specification to start from — request an RFQ via the Simiai Technology trade desk.
