Reverse Circulation Drill (RC Drill) is a drilling equipment that uses compressed air to circulate and discharge slag. Its core principle is to use a double-wall drill pipe structure to quickly discharge rock cuttings through the inner tube to avoid the risk of hole plugging in traditional positive circulation drills. Taking the YG RC-800 drill as an example, it is particularly good at hard rock formations such as granite and basalt (compressive strength ≤300MPa). Click to get a customized exploration plan!

RC drilling machine application range
Reverse circulation drilling rigs are widely used in the following applications due to their high sampling accuracy and strong formation adaptability:
- Mineral exploration: Rapidly obtain continuous rock cuttings samples of metal ores (gold, copper, lithium), with a grade analysis error rate of <3%;
- Water well construction: Drilling deep wells in arid areas, with a single hole daily footage of up to 50 meters;
- Pile foundation engineering: Providing large-diameter rock-embedded pile holes for cross-sea bridges and wind power bases (such as the Jakarta-Bandung high-speed rail project in Indonesia);
- Environmental monitoring: Accurately collect samples of contaminated soil layers to support ecological restoration;
- Scientific research drilling: Research on polar ice layers and active volcanoes.
Case: A gold mine in Australia used a YG RC drill rig to complete 200 exploration holes within 3 months, and the accuracy of vein positioning increased by 40%.
Advantages of reverse circulation drill rig
- Efficient slag removal: The double-wall drill rod design enables a chip removal speed of 40m/s, and the drilling efficiency is increased by 60%;
- Pure samples: The cuttings do not contact the hole wall, and the metal mineral recovery rate is as high as 98%;
- Controllable costs: Consumable wear is reduced by 30%, and the comprehensive operation and maintenance cost is reduced by 25%;
- Environmental protection and safety: The closed circulation system reduces dust spillage, and the noise is less than 85 decibels;
- Flexible adaptation: The modular design supports multiple deployment methods such as trucks, crawlers, and ships.
