A coal mine collapse turns every minute into a rescue-window race. The rig that arrives first must punch a life channel, a ventilation rescue hole or a drainage bore through collapsed rubble on its own tracks, operators standing by remote control outside the danger zone. Below, each mission is matched to real crawler rigs and their spec parameters.
Rescue duty is not production drilling: the hole must reach miners fast, the rig must stand off from danger and arrive without a paved road.
A rescue rig is judged on the hole it delivers: a 300 mm life channel, a smaller ventilation hole, or a drainage bore. The DD-05DL reaches 200 m at 300 mm; the ST-R800 drilling rig extends rescue to 650 m at 300 mm and cores to 800 m.
Gassy seams need guarded drive, spark-resistant breakout and stand-off control. The DD-05DL drilling rig runs on wireless remote plus a local console with overload protection and an emergency stop. The DH190 drilling rig adds impact pipe-pulling and offers explosion-proof electric drive.
After a collapse there is no time for crane erection. A crawler unit drives itself over rubble, then levels and raises the mast hydraulically. The ST-C600 drilling rig is a light 2600 kg tracker; the ST-400 supplies relief water and grouting wells near base.

A dedicated full-hydraulic crawler rescue unit for mine collapse relief, with wireless remote operation away from the danger zone.
Beyond the 200 m first-arrival class: deeper rescue, broken-ground relief and base support:

| Rescue mission | Hole profile | Rig capability needed | Recommended model |
|---|---|---|---|
| Large life channel through rubble | 300 mm, up to 200 m | 12000 N-m head, remote control | DD-05DL |
| Medium-depth rescue plus standby coring | 300 mm rescue, 75-110 mm core | 650 m rescue, auto leveling | ST-R800 |
| Tunnel and slope broken-ground relief | 110-320 mm, 30-190 m | Impact pipe pulling, multi-angle mast | DH190 |
| Relief water and grouting wells at base | 110-150 mm, up to 400 m | Compact skid, low maintenance | ST-400 |
Rescue fleets are configured around hole diameter, feed force and control options, so buyers open with a mission brief.
Search a rescue drilling rig for sale, compare a rescue drilling rig price, or ask a rescue drilling rig supplier and rescue drilling rig manufacturer about explosion-proof drive. As a rescue drilling rig exporter shipping from Jingzhou, HuBei SJ packs tooling, spares and export paperwork with each unit; the coal mine drilling rig price gap between a 200 m life-channel and an 800 m dual-purpose class is driven by head torque and hoist, so most teams first request a rescue drilling rig quotation.
First-arrival: request a DD-05DL drilling rig quotation for rubble access, compare the DD-05DL drilling rig price, source a DD-05DL drilling rig for sale with remote-control stand-off; each DD-05DL drilling rig supplier bundles that kit. Broken ground: the DH190 drilling rig for sale adds impact pipe pulling, the DH190 drilling rig price reflects its multi-angle mast, and the DH190 drilling rig supplier confirms explosion-proof drive. Support duty: an ST-400 drilling rig for sale covers relief wells, the ST-400 drilling rig price stays compact, and an ST-400 drilling rig quotation ships without crawler drive. A drilling rig for coal mine rescue that also samples ahead uses the ST-R800 drilling rig; a lighter drilling rig for coal mine survey uses the ST-C600 drilling rig.
Life-channel holes run to 200 m at 300 mm on the DD-05DL; the ST-R800 reaches 650 m rescue at 300 mm.
Gassy seams need guarded, spark-resistant drive and stand-off control. The DH190 offers explosion-proof electric drive; the DD-05DL runs wireless remote outside the collapse zone.
Crawler units drive themselves over rubble, then raise the mast hydraulically. The DD-05DL climbs 30 degrees and travels to 3.5 km/h, dropping crane delays.
The ST-400 drills 400 m relief water and grouting wells at 110-150 mm, skid-mounted for base-camp supply rather than life-channel duty.
