Product Description
Reverse circulation multifunctional drilling rig is a new efficient, environmentally friendly, and multifunctional tracked drilling rig.lt adopts the latest RC drilling and mining technology from abroad, and drilling dust can be effectively collected through dust collectors, avoiding environmental pollution. lt can also be collected and discharged through a cyclone separator, which can be used for sampling and analysis work in geological exploration departments.lt is the preferred equipment for geological exploration drilling and other deep holes.
This drilling rig can use compressed air reverse circulation down-hole drilling on various formations. The lifting of the drilling rig frame, compensation of the drilling frame/multi angle drilling unloading of the drill pipe rotation and feeding,support legs ,hoisting,walking and other movements are all achieved by the hydraulic system, greatly reducing labor intensity, improving construction efficiency and engineering quality.

Our Advantage
The RC Reverse Circulation Drill, with its unique gas reverse circulation process, has demonstrated significant advantages in mineral exploration, hydrological drilling, and basic engineering. Here are its core advantages:
1, High precision sampling and geological interpretation
1. Sample integrity guarantee:
Double walled drill pipe design (outer tube for air supply, inner tube for slag return), with rock debris rising at high speed through the central channel (flow velocity ≥ 25 m/s), avoiding secondary mixing with the borehole wall, * * sample contamination rate<5% * *, greatly improving the accuracy of ore body grade assessment.
2. Continuous undisturbed sampling:
Continuous columnar samples can be obtained without lifting the drill (such as RC300 drilling rig with a single sampling rate>95%), especially suitable for exploration of precious metals such as gold mines, reducing the risk of ore leakage.
2, Efficient drilling and cost optimization
1. Strong penetration through hard rock:
High pressure air compressor (≥ 24 bar) drives down the hole hammer, combined with reverse circulation slag removal, * * drilling efficiency can reach 2-3 times that of conventional positive circulation * *. For example, the RC600 drilling rig has an average daily footage of over 80 meters in granite formations.
2. Comprehensive cost savings:
-* * Time cost * *: Reduce the number of drilling operations (only one rod connection is required every 30 meters), with auxiliary time accounting for less than 15%;
-Consumable cost: drill bit life extended by 30% (no repeated grinding of rock debris);
-Water and electricity costs: Dry drilling does not require a mud circulation system, saving 100% water.
3, Adaptability to complex geological formations**
1. Dealing with fractured zones and leaking layers:
Gas medium (non liquid) drilling can avoid mud leakage and maintain stable borehole walls in karst landforms or fractured areas (such as a successful drilling of 300 meters in a fractured zone in a gold mine project in Xinjiang).
2. Advantages of working in arid areas:
No water source required, suitable for water scarce environments such as deserts and plateaus, expanding exploration scope.
4, Environmental protection and safety improvement
1. Dust controllability: The closed slag discharge system (equipped with a cyclone dust collector) ensures that the dust concentration at the work site is less than 5 mg/m ³, which is better than that of an open-pit down the hole drilling rig (>20 mg/m ³).
2. Low vibration and low noise:
The shock absorption design of the drill string attenuates surface vibrations by 40% and controls noise below 85 dB, reducing the impact on the surrounding environment.
5, Multi functional expansion capability
1. Process compatibility:
Through modular modification, it can be switched to * * positive air circulation, foam drilling or coring mode * * (such as the Sherm T4WD drill), covering a hole diameter of Φ 120 - 350 mm, with a depth of 600 meters.
2. Deep hole economy: In boreholes deeper than 500 meters, the comprehensive cost is about 35% lower than diamond rope coring, making it the preferred choice for large-scale porphyry copper exploration.
Application scenarios and cases
-Mineral Exploration: The Super Pit gold project in Australia uses RC drilling rigs, with an annual footage of over 500000 meters and a resource verification error of less than 3%;
-* * Disaster Management * *: Achieving rapid perforation in landslide anchoring engineering (only 1.5 hours for a Φ 150 mm × 40 m hole);
-Water well construction: The construction period of a 300 meter deep foundation rock well in arid areas has been shortened to 5 days.
The RC reverse circulation drilling rig has become the "gold standard" for modern resource exploration due to its core competitiveness in high fidelity sampling, efficient penetration of hard rocks, adaptability to complex formations, and low-carbon operations. With the increasing demand for deep mining and the popularity of intelligent control systems such as automatic pressure regulation, its technological and economic advantages will be further highlighted.
