XH‑2200 Core Drill Rig: 1,740 m On‑the‑Ground Record in Ghana — A Deep‑Hole Workhorse That Delivers

When we say the XH-2200 core drill rig is engineered for tough deep-hole conditions, we’re not just repeating brochure claims — we’re backing it up with real, on-site drilling data. On a mineral exploration project in Ghana, one XH-2200 drilled through complex, abrasive formations to reach a total depth of 1,740 meters, delivering consistent, high-quality core samples throughout the entire operation. It’s this proven depth record under real working conditions that sets the rig apart for drilling contractors and exploration firms who rely on stable, high-performance equipment.

Below, we break down why the XH-2200 has become the spindle-type core drill of choice for deep mineral exploration, what applications it’s built for, and how to work with Xinhao Drilling for project-scale procurement. Please note: we supply direct from the factory and work with distribution partners only — this is not a retail product.

Key Advantages of the XH-2200 for Reliable Deep-Hole Drilling

1. Rated Depth Backed by Verified Field Performance

Its rated drilling depth ranges from 1,200 to 2,400 meters, depending on drill rod size (NQ/HQ/PQ) — and the 1,740-meter record in Ghana confirms this capability in real-world use.

Powered by a 75 kW electric motor or 84 kW diesel engine, the rig maintains steady torque and penetration rates even as depth increases and operating loads rise.

This is not a theoretical maximum. The Ghana record was achieved under standard project conditions with standard wireline coring tools — not in a controlled lab test.

2. Hydraulic Feed + Spindle Drive for Better Core Quality and Smoother Operation

The XH-2200 pairs a fully mechanical spindle structure with a hydraulic feed system — a combination refined over decades of field use for proven, reliable performance:

Maximum torque of 7,800 N·m delivers ample rotational power for impregnated diamond bits, even in hard rock formations.
Its 720 mm spindle stroke is long enough to maintain consistent bit pressure without frequent chuck changes.
The smooth, responsive feed helps operators hold optimal penetration rates while preserving core integrity — a critical factor for project owners who demand high recovery rates and accurate geological data.

3. Wide RPM Range for Varied and Complex Ground Conditions

Spindle speed can be adjusted to match everything from soft oxidized zones to solid granite. This wide RPM range also means you aren’t locked into a single drilling method. Contractors most often use the XH-2200 for diamond coring, but it works equally well with TC bits or roller bits when conditions require. This versatility reduces the need to mobilize a second rig on site.

4. Safety-Focused Hoisting System with Low-Position Controls

The main hoist delivers 85 kN of single-line pull, with more than enough power for smooth tripping in deep holes.
Fitted with a water brake, it lowers heavy drill strings in a controlled, jolt-free manner — protecting the drill string and, most importantly, reducing safety risks for the crew.
Controls are positioned at a low working height, so the driller can monitor the hole and hoist in real time without climbing or operating levers blind. It’s a small design detail that makes a big difference for crews working long shifts.

Applications of the XH-2200 Core Drill Rig

This is a truly versatile core drill, used across a wide range of applications:

Metallic and non-metallic solid mineral exploration (gold, copper, iron, lithium and more)
Geological mapping and geotechnical investigation
Coal exploration and hydrogeological drilling, including deep water well construction
Shallow oil & gas appraisal wells, mine ventilation holes and dewatering holes
Large-diameter foundation drilling where rotary coring is specified

The mast handles holes from vertical down to 75° angles, with full 360° rotation. It handles angled exploration holes in mountainous terrain and drilling on confined job sites with ease.

What the 1,740-Meter Ghana Record Means for Your Project

Conditions on the Ghana site were no easy test. The drilling crew had to work through weathered overburden, fractured rock zones and solid hard rock — exactly the kind of mixed, alternating formations that expose weaknesses in a rig. Throughout, the XH-2200 maintained mechanical stability, ran efficient wireline coring cycles, and delivered the core recovery rates the geology team required.

For drilling contractors, this translates to:

Fewer days on site: deep-hole operation with no major downtime
Better project margins: high core recovery reduces disputes and the risk of re-drilling
Longer rig life: its robust, straightforward mechanical design delivers lower total cost of ownership and easier field maintenance compared to rigs with complex electronic controls

If your next tender calls for drilling depths above 1,500 meters, the XH-2200 belongs on your shortlist — and you now have real field data to back up that choice.
