CMD100 – Multifunctional Large-Diameter Drilling Rig

Engineered for Coalbed Methane, Geothermal & Emergency Mine Rescue

The CMD100 multifunctional large-diameter drilling rig is a fully hydraulic workhorse designed for coalbed methane (CBM) development, emergency mine rescue, and geothermal energy projects in complex geological settings. With 100-ton hoist capacity, tri-mode circulation, and setup in under 4 hours, it delivers precision, safety, and adaptability where versatility matters most.

Adaptable to Any Formation

As a true large-diameter drilling rig, the CMD100 handles diverse ground conditions without rig reconfiguration:

Air drilling: Efficient in hard rock and dry zones

Mud rotary: Stabilizes water-sensitive or unstable strata

Foam-assisted: Optimizes cuttings removal in low-pressure formations

Its 810 mm (32") max hole diameter and 105 mm spindle through-hole accommodate standard casing strings, while the dual-speed power head delivers 27,500 N·m torque—ensuring smooth transition from pilot holes to full-diameter production wells.

Safety-First for High-Risk Environments

Built for gas-prone and rescue-critical operations:

Cummins KTA19-P750 diesel engine (559 kW / 750 HP) for remote reliability

100-ton hoist + 20-ton downforce for heavy drill strings

Integrated BOP platform at 2.08 m height, compliant with API RP 53 well-control standards

Six hydraulic stabilizers with real-time pressure monitoring

All systems feature safety interlocks and smooth weight-on-bit regulation to prevent tool failure during extended runs.

Rapid Deployment, Global Provenance

The CMD100 disassembles into road-transportable modules (14.56 m × 2.95 m × 4.25 m, ~55 tons) and sets up in under 4 hours. It has been deployed across China’s Shanxi coal basin, Australian mines, and European geothermal sites—fitting confined urban yards, mountain pads, and emergency response zones.

Key Applications

Coalbed methane: Vertical, directional, and horizontal wells

Mine rescue: Communication boreholes, evacuation shafts, air supply lines

Geothermal: Large-diameter injection/production wells

Infrastructure: Deep water wells, slope stabilization, foundation piling

Certified to ISO 9001 and CE, the CMD100 is backed by global technical support and 48-hour spare parts dispatch.
