Large Diameter Drilling Rigs – Powering Coalbed Methane, Geothermal & National Mine Rescue

Engineered for the world’s most demanding subsurface challenges, our large diameter drilling rigs deliver unmatched performance in coalbed methane (CBM) development, deep geothermal energy, and emergency mine rescue operations. With models ranging from compact multifunctional units to ultra-heavy national-response platforms, every rig is built for hole diameters up to 1,219 mm (48 inches) and depths exceeding 5,000 meters—combining industrial strength with rapid deployment.

Whether you’re drilling horizontal CBM wells in mountainous terrain, installing urban geothermal arrays, or executing life-saving rescue boreholes, we offer a purpose-built large diameter drilling rig that reduces mobilization time, ensures operational safety, and lowers total cost of ownership.

Our Large Diameter Drilling Rig Series

Each CMD model addresses specific mission profiles. Explore the lineup below:

· CMD100 – A multifunctional large diameter drilling rig ideal for coalbed methane drilling and emergency mine rescue. Features tri-mode circulation (air/mud/foam), 810mm max hole, and setup in under 4 hours.

· CMD130L – A tracked large diameter drilling rig designed for steep-slope CBM and alpine geothermal projects. Operates safely on gradients up to 30° with low-ground-pressure crawlers.

· CMD130DL – An electric large diameter drilling rig offering zero-emission, low-noise operation—perfect for urban geothermal and eco-sensitive coalbed methane drilling near residential zones.

· CMD130 Truck – The only highway-legal truck-mounted drilling rig in the series. Enables rapid response for multi-well CBM campaigns or emergency mine rescue with no crane required.

· CMD150 – A modular large diameter drilling rig transportable by helicopter or container. Built for ultra-deep geothermal wells (>3,000m) in remote frontiers like Arctic tundra or volcanic highlands.

· CMD180 – A heavy-duty drilling rig certified for national mine rescue commands. Drills 48-inch rescue boreholes to 5,000m with dual 760HP engines and fail-safe redundancy.

Frequently Asked Questions

What’s the best large diameter drilling rig for coalbed methane horizontal wells?
The CMD100 and CMD130L are both widely used for CBM, including directional and horizontal sections. The CMD100 offers faster setup for single-well pads, while the CMD130L excels on steep, roadless terrain.

Can I use an electric drilling rig for deep geothermal projects?
Yes. The CMD130DL supports depths up to 2,500m and is ideal for urban or environmentally regulated geothermal zones. For deeper wells (>3,000m), the diesel-powered CMD150 or CMD180 are recommended.

Is the CMD130 Truck suitable for national mine rescue?
While the CMD130 Truck provides rapid deployment for regional emergencies, national-level mine rescue missions typically require the higher capacity and redundancy of the CMD180, which is certified to government emergency standards.

How quickly can these rigs be transported to remote sites?

· CMD100/CMD130L: Road-transportable in standard modules

· CMD150: Disassembles into helicopter-liftable sections (<5 tons each)

· CMD130 Truck: Self-propelled, highway legal—ready to drill within hours

Ready to Select Your Large Diameter Drilling Rig?

Choosing the right rig depends on:

· Target depth and hole diameter (up to 48")

· Terrain accessibility (urban, mountainous, off-grid)

· Environmental regulations (emissions, noise)

· Mission criticality (routine CBM vs. life-saving rescue)
