**BCZ400 Truck-mounted Drilling Rig: Technical Parameters & Applications**

The BCZ400 is a high-performance, truck-mounted rotary drilling rig designed for efficiency, depth capacity, and versatility across demanding drilling operations.

**Key Technical Parameters:**

*   **Drilling Capacity:**

    *   **Maximum Drill Depth:** Up to 400 meters (≈1,312 ft) with N-size drill pipe (specific geology dependent).

    *   **Hole Diameter Range:** Typically 90mm to 250mm (≈3.5" to 10"), adaptable based on method and tools.

*   **Power & Drive System:**

    *   **Prime Mover:** Powered by a high-torque diesel engine.

    *   **Drive System:** Fully hydraulic system for precise control of all functions (rotation, feed, hoisting).

*   **Main Components:**

    *   **Mast:** High-strength, telescopic or foldable mast with a safe working load suitable for 400m drilling.

    *   **Rotary Head:** High-torque hydraulic rotary head, offering variable rotational speeds.

    *   **Feed System:** Long-stroke hydraulic feed system for efficient drilling and rod handling.

    *   **Hydraulic System:** Advanced closed-loop or open-circuit system for responsive and reliable operation.

*   **Optional/Auxiliary Equipment:** Can be configured with a mud pump, air compressor (for DTH hammer drilling), or water injection system.

*   **Carrier Vehicle:** Heavy-duty, all-terrain truck chassis providing excellent mobility and site stability.

**Primary Application Fields:**

The BCZ400 is engineered for a wide range of medium-to-deep drilling projects, including:

1.  **Geological Core Exploration:** For mineral prospecting and resource evaluation.

2.  **Hydrogeological Drilling:** For constructing water wells, groundwater monitoring, and dewatering wells.

3.  **Geotechnical Investigation:** For soil sampling, standard penetration testing (SPT), and foundation engineering surveys.

4.  **Environmental Drilling:** For soil/groundwater sampling and monitoring well installation.

5.  **Shallow Oil & Gas Exploration:** For seismic shot-hole drilling and stratigraphic exploration.

6.  **Geothermal Drilling:** For installing shallow geothermal loop systems (borehole heat exchangers).

7.  **Foundation Engineering:** Drilling for micropiles, anchor holes, and grouting holes.

**Summary:**

The BCZ400 rig combines robust drilling power (400m depth capacity), flexible configuration options, and superior mobility, making it a highly productive and cost-effective solution for the construction, mining, energy, and environmental sectors.
