Overview

The JTRC-200 redefines medium-depth hard rock drilling with a reverse circulation (RC) design built for sample purity and operational efficiency. Unlike traditional pneumatic rigs, it centers on uncontaminated core recovery and targeted water well construction—making it the go-to choice for mineral exploration teams, geotechnical engineers, and water resource specialists who demand precision over brute force. Powered by a Yuchai 4-cylinder diesel engine, this crawler-mounted rig balances compact transportability with field-ready durability for global 200-meter drilling projects.

Core Differentiators: Reverse Circulation at Its Best

1. Sample Integrity First

Reverse circulation technology is the JTRC-200’s defining strength: cuttings and core samples travel up the inner drill pipe, eliminating cross-contamination from surrounding formations. For mineral exploration, this means pristine geological data; for water well drilling, it ensures accurate aquifer identification—critical for reliable long-term water supply. Paired with a penetration rate of 10–35m/h, it delivers speed without sacrificing sample quality, even in hard rock (F=6~20).

2. Hydraulic Precision for Hard Rock

A 77.3kW Yuchai engine drives a high-torque rotary system (5300–7600N·m) and 15T power head lifting force, engineered to bite into granite, basalt, and compacted strata. The 3.6m one-time advance length cuts down on rod changes, while hydraulic crawler traction maintains steady power delivery across uneven ground—no jolts, no lost progress, just consistent drilling.

3. Built for Remote, Rugged Sites

The heavy-duty steel crawler chassis and 4 hydraulic high legs create a stable platform for drilling on slopes up to 30°. With a 2150mm track contact length, it exerts low ground pressure, protecting fragile soils and accessing sites wheeled rigs can’t reach. At 6T and 6000×1750×2350mm, it transports easily between remote exploration camps and rural well sites, minimizing setup time.

4. Flexible Configuration for Every Project

Drill pipe options (Φ89/Φ102mm diameters, 1.5/2/3m lengths) and a 95–165mm hole diameter range let teams tailor the rig to their goals: narrow core holes for mineral sampling, wider bores for water wells, or precision boreholes for geotechnical testing. It’s a single platform that adapts to the full spectrum of 200-meter drilling needs.

Where It Shines

···Mineral Exploration: Uncontaminated core sampling for resource assessment and mining feasibility studies.

···Hard Rock Water Wells: 200m well construction in rocky terrain for rural communities and agricultural operations.

···Geotechnical Testing: Precision boreholes for soil/rock mechanics analysis and foundation design.

···Environmental Monitoring: Clean sampling for groundwater quality and aquifer mapping projects.
