Core Drilling Machine For Mining

Product Description:
The power unit of the YGQY-800, a reliable core drilling machine for mining exploration, consists of a diesel engine and a hydraulic pump assembly; the engine brand can be selected according to customer requirements. This hydraulic core drilling machine adopts a well-structured hydraulic system organized into distinct circuits for rotation, feed, lifting, and clamping, with independent pressure regulation for each circuit to ensure that the various actuators operate without mutual interference. The hydraulic oil tank is equipped with a dedicated cooling circuit, which keeps the oil temperature under control during prolonged, continuous operation—preventing performance degradation caused by high heat and the premature aging of seals. The electrical and instrumentation systems are centralized on the control console, allowing for real-time monitoring of operational parameters such as pressure, oil temperature, and rotational speed. Furthermore, the core drilling rig includes pre-configured mounting interfaces for night-time lighting, a climate-controlled (heated/cooled) operator cabin, and an onboard drill rod rack, facilitating all-weather, round-the-clock drilling operations for mineral survey and mining resource evaluation in the field.

Product Features:
This Core Drilling Machine features a fixed operator station at the control console, with hydraulic systems handling the clamping, making up, and breaking out of drill rods at the borehole collar. This eliminates the need for manual handling of pipe wrenches, significantly reducing the time personnel must spend exposed at the borehole. Furthermore, the hydraulic circuit incorporates pressure-limiting protection—ensuring that in the event of a stuck drill string, pressure is relieved before any intervention—thereby lowering risks to both the equipment and the operating personnel. The power head advances linearly along the mast guide rails, keeping the drill string constrained throughout the entire operation. The long-stroke design also reduces the frequency of rod-handling cycles, making it easier to control borehole deviation and minimizing the need for corrective rework or the abandonment of misaligned holes. The system is operated via hydraulic pilot-controlled joysticks, which require fewer manual inputs and provide direct, intuitive feedback. Operators accustomed to traditional spindle-type drill rigs can achieve proficiency after only brief training, allowing the crew to reach full operational productivity shortly after arriving on-site.

Application Scenarios：
This machine is designed for advanced geological forecasting in tunnel and underground engineering. By drilling core samples ahead of the tunnel face, it enables the assessment of surrounding rock classification and the identification of structural fracture zones, providing a basis for adjusting support parameters. It is also suitable for site investigations related to slope stabilization and geological hazard mitigation; by extracting continuous core samples from landslide masses, collapse zones, or unstable slopes, it helps determine the depth of sliding surfaces, the degree of rock weathering, and the distribution of weak interlayers—data essential for designing anchoring and drainage systems. Furthermore, in overseas engineering contracts and foreign aid projects—such as those involving highways, railways, ports, or water conservancy infrastructure—the equipment can be used for supplementary geological verification drilling. As it can be easily relocated along the project route, it provides primary core data to support design modifications and the verification of construction quantities.
