Hydraulic Core Drilling Machine

Product Description:
This hydraulic core drilling machine is built to address common challenges in field geological exploration and medium-to-deep hole drilling—such as difficult site transitions, slow core recovery, and poor adaptability to varying strata. The hydraulic core drilling rig integrates a top-drive rotary system, a wireline coring mechanism, and a self-propelled crawler undercarriage for flexible field deployment. Upon arrival at the site, the core drilling machine maneuvers into position on its own crawler tracks, with hydraulic outriggers providing automatic leveling. The mast, operated by hydraulic cylinders, can be raised, lowered, and extended, allowing for drilling at any angle—from vertical and inclined to horizontal. During operation, the power head’s rotational speed, feed pressure, and hoisting speed are all fully hydraulically adjustable, enabling real-time parameter optimization to maintain peak drilling performance even when encountering alternating soft and hard rock layers. Once the inner core barrel is full, it can be retrieved directly from the borehole using a wireline retrieval tool, eliminating the need to pull out the entire drill string; this hydraulic core drilling machine delivers longer individual drilling runs and significantly reduced auxiliary downtime for mineral exploration and geological coring jobs.

Product Features：
1. Rapid core-retrieval cycle with minimized auxiliary time: A high proportion of each operational cycle is dedicated to effective drilling and core recovery. Seamless transitions between rod addition, core retrieval, and system resetting ensure consistent daily footage, offering better project timeline predictability compared to traditional core-drilling methods.
2. High core integrity with preserved stratigraphic boundaries: The inner tube provides continuous protection for the core, while a core-catcher mechanism prevents slippage or loss. Geological interfaces and weak interlayers remain intact, ensuring that samples used for geological logging and grade assaying are highly representative.
3. Reduced operational burden with clear, real-time parameter monitoring: The control console is centrally organized, allowing for immediate visibility of key parameters such as rotational speed, weight on bit (WOB), lifting force, and hydraulic oil temperature. A single operator can manage both the drilling process and auxiliary tasks—such as rod handling or rig repositioning—significantly shortening the training period for operators.
4. Controllable maintenance costs and high spare-part interchangeability: The system utilizes standardized hydraulic components and wear parts, ensuring excellent field replaceability. Its modular design ensures that a single-point failure does not necessitate a full-machine teardown, resulting in less downtime and reduced pressure regarding spare-part inventory.

Application Scenarios：
1. Resource Exploration: Borehole placement for all stages—from preliminary reconnaissance and detailed investigation to full-scale exploration—of metallic mineral deposits (such as gold, copper, iron, lead-zinc, tungsten, and tin) and various non-metallic mineral deposits. This includes delineating ore body boundaries, grade-control drilling, and supplementary or deep-extension exploration for active mines.
2. Engineering Investigation: Site investigations for pumped-storage and conventional hydroelectric power stations (including dam sites, tunnels, and water diversion routes); foundation assessments for bridges and high-rise buildings; stability evaluations for tailings dams and waste rock dumps; and the detection of mined-out voids or karst-developed zones.
3. Geological and Specialized Surveys: Regional geological mapping and profile-control drilling; structural analysis of fault zones and landslide masses; identification of the overburden-bedrock interface; and investigations into groundwater resources and shallow geothermal energy.
