Description
In the core fields of resource exploration and geological research, the core sample drilling rig undertakes the crucial mission of extracting original archives from deep within the Earth. This type of equipment provides irreplaceable first-hand evidence for mineral assessment, engineering geology and scientific research by obtaining complete cylindrical samples (cores) of the strata. Its value lies not only in the drilling depth, but also in the ability to maintain the original structure of the formation and the state of mineral occurrence - this is a precision revolution that ordinary drilling cannot reach.
Modern lightweight core extraction systems such as Yanlin YDF-700X perfectly integrate laboratory-level accuracy with field adaptability.
It is equipped with a 92kW Yuchai six-cylinder engine, combined with an intelligent hydraulic distribution system (20MPa/220L/min), achieving a delicate balance between power and energy consumption. The core power head has a stepless torque adjustment capability ranging from 450 to 1300N·m. Within a wide speed range of 0 to 1300rpm, it can automatically match the optimal cutting parameters for different rock types such as gneiss and quartz veins. The revolutionary design lies in the modular core-sampling solution - the standardized BW120 mud pump works in coordination with the hydraulic gripper to ensure that the φ75mm core sampling rate remains above 90% under different hole depths ranging from 350 to 800 meters. What is even more commendable is its mobility: with a self-weight of 5 tons and a rubber track chassis, it has the ability to climb a 40° steep slope and a traveling speed of 3.5km/h, enabling it to cross suspension Bridges and mountain roads to reach secret places that traditional drilling RIGS cannot access. The 4.2-meter ultra-short fuselage (in transportation condition) can even be transported by pickup trucks, significantly reducing the logistical pressure on the exploration team.
This type of stratum sampling platform is driving breakthroughs in multiple fields: In the geothermal exploration of hot dry rock, the complete core it acquires helps scientists accurately calculate the heat flow value; In the study of paleoenvironment, the non-destructive extraction of lake core sediments has recreated climate change over ten thousand years. In the exploration of rare metals, the mineral crystal forms within the primary fractures of the core have become the key evidence for mineralization prediction. Its irreplaceability stems from three major characteristics: The standardization of core diameter meets the analysis requirements of global laboratories; Thin-walled diamond drill bits minimize thermal disturbance. Real-time core orientation technology provides spatial data for geological structure analysis. Today, with the rapid development of digital exploration technology, the high-fidelity core sample drilling rig remains the ultimate arbiter of geological truth.
