Rope Drilling Tool
___________________________________________________________________ Rope core drilling tool is a drilling tool that retrieves rock cores from the drill rig without lifting the drill. The complete set of drilling tools includes: drilling assembly, salvager, drill rod, winch, hoist, gripper, and free lance components.
It has the advantages of high drilling efficiency, high core recovery rate, long drill bit life, and low labor intensity. As the drilling depth increases, its advantages become more apparent.
Double Tube Core Barrels
---TT Series Core Barrel Ultra-thin walled double tube core barrels, available diameters 46 and 56 mm. Very thin cutting face allows very rapid rate of penetration through hard formations.
They are suitable for underground mining applications.
---T2 Series Double Tube Core Barrels The T2 Series are thin wall double tube core barrel, used for surface exploration, especially mining applications.
Due to their thin kerf, these core barrels provide rapid penetration. Available in diameters 46, 56, 66, 76, 86, 101mm.
---T6 Series Double Tube Core Barrels These are a continuation of the T2 series, but of a sturdier design and available in larger diameters, 76, 86, 101, 116. 131 and 146mm.
They are applied in surface mining and geotechnical drilling.
---LTK 48 & LTK 60 Double Tube Core Barrels The LTK series core barrels system is a thinner wall core barrel than T2 series. They offer a cost effective, high production, which is designed for optimum production and core recovery in medium to extra hard rock formations.
Available sizes 48 and 60mm.
---WF Series Double Tube Core Barrels They are geotechnical core barrels primarily designed for coring relatively soft formations in using face-discharge bits. Simple construction and more resilient to damage than thin-wall barrels,but with slower enetration rate.
---WG Series Double Tube Core Barrels There are Double tube core barrels for WG series. Available in DCDMA sizes E, A, B, N, and H.
---TBW and TNW Core Barrels
These are thin-walled double tube core barrels, as T2 series but with DCDMA hole sizes B and N. Used for surface exploration, specially mining applications.
The thin kerf area allows rapid penetration.
---Wireline Double Tube Core Barrels Wireline double core barrels are primarily used in deep coring. With an overshot device, they eliminate the need to couple and uncouple the rod string each time the core is retrieved. Available in DCDMA sizes A, B, N, H ,and P.
---Chinese Standard Double Tube Core Barrels
---Chinese Standard Wireline Double Tube Core Barrels
---Jet-type Reverse Circulation Double Tube Core Barrels
Hunan Yuanyu Exploration Technology Development Co., Ltd
Our company was formerly known as Hunan Zhuangyuan Geological Equipment Co., Ltd., which was affiliated with Hunan Provincial Institute of Geophysics and Geochemistry. The company was developed from the original 409 team mechanical repair workshop. In 1989, 409 Repair Factory was established. In 1992, Diamond Products Research Institute was founded. In 2003, Zhuangyuan (Group) Company was established, which includes Hunan Zhuangyuan Diamond Products Co., Ltd. and Hunan Zhuangyuan Geological Equipment Co., Ltd. In 2016, Hunan Yuanyu Exploration Technology Development Co., Ltd. was jointly established with Hunan Hongyu Water Resources and Hydropower (Group) Co., Ltd. It is a national high-tech enterprise specializing in the design, production, scientific research and development, and operation services of geological equipment such as drilling rigs, drilling tools, diamond drill bits, and centralized slurry injection equipment. In terms of emergency equipment, the company's developed "centralized slurry grouting system" has been shortlisted for the first batch of recommended emergency equipment procurement list in Hunan Province.
In recent years, the company has also received various awards: the "Zhuangyuan" brand has been awarded the "Famous Trademark of Hunan Province" multiple times, and has been awarded the "Hunan Province Contract abiding and Creditworthy Unit" and "Hunan Province Integrity Construction Demonstration Unit" multiple times. And awarded the title of "National High tech Enterprise" in 2021.
The company attaches great importance to technological innovation, and currently has more than 10 patents. It has maintained close ties with China University of Geosciences (Wuhan) and Central South University for a long time, and is now the industry university research base of China University of Geosciences (Wuhan). At the same time, the marine shallow sampling drilling rig jointly developed with the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences has received high praise from users.
