Deep-hole drilling technology is a core support for geological exploration, mineral resource development and engineering construction. With the growth of energy demand and improvement of engineering standards, it is accelerating upgrading toward deeper, faster, smarter and more eco-friendly. Jiangsu Sinocoredrill Exploration, based on the industry frontier, integrates full-hydraulic, modular and intelligent design concepts to launch the CR-18A Full-Hydraulic Deep-Hole Core Drilling Rig, providing an integrated solution for kilometer-level deep-hole operations under complex geological conditions.
Reviewing the development history of deep-hole drilling, equipment has gradually moved from manual machinery to electric-hydraulic, and then to automation and intelligence. At present, high-precision positioning, intelligent control, high-efficiency energy saving, remote monitoring and green environmental protection have become mainstream trends. Equipment selection emphasizes five core factors: geological adaptation, depth matching, safety and reliability, cost control, convenient operation and maintenance. CR-18A precisely targets selection points with engineering thinking to fully meet efficient deep-hole drilling needs.
The rig is equipped with CUMMINS QSB 6.7-C240-30 diesel engine, 6.7L 6-cylinder power, rated power 178kW (240HP), with strong power and excellent fuel economy. Drilling capacity covers multi-caliber deep-hole operations, suitable for metal mines, geothermal, shale gas and deep geological surveys.
