1. Features a maximum drilling depth of 800 meters and utilizes the Down-The-Hole (DTH) percussion drilling method. It supports hole diameters ranging from Φ100 mm to Φ298 mm and accommodates deep-hole casing operations, effectively handling fractured or broken formations and reducing the risk of borehole collapse. 2. Equipped with a high-load-capacity crawler undercarriage featuring shock-absorbing components and four independently adjustable hydraulic outriggers; this setup ensures flexible leveling and enhances overall machine stability during deep-hole operations. 3. Combines a heavy-duty lifting winch with a long-stroke feed rail and a high-power hydraulic rotary head. It delivers high lifting capacity to meet the demands of tripping drill strings at depths of 800 meters and includes an auxiliary drill rod locking mechanism. 4. Employs high-pressure, explosion-proof fittings for all pneumatic and hydraulic lines, along with multiple pressure-sensing monitoring systems. These provide real-time monitoring of air pressure and hydraulic loads, enabling operators to stay informed of downhole conditions.

Product Description ： The YGQZ-800 is a high-performance, deep-hole pneumatic DTH (Down-The-Hole) drilling rig designed specifically for developing medium-to-deep bedrock water wells. It offers a maximum drilling depth of 800 meters and supports borehole diameters ranging from 120 mm to 298 mm. Featuring a self-propelled crawler design, the rig utilizes high-pressure air supplied by an external compressor to drive the DTH hammer for rock fragmentation, while using airflow to clear cuttings from the borehole. Its structure is optimized for drilling through alternating soft and hard rock strata and fractured rock formations, making it suitable for a variety of applications, including deep wells for potable water, industrial water supply wells, mine dewatering holes, and hydrogeological test holes.
Product Features： 1. Powerful deep-hole drilling capabilities: The main hoist easily handles the weight of a full 800-meter drill string, with controllable hoisting and lowering speeds that minimize impact damage to the drill rods. 2. Shock-absorbing structural design: Effectively dampens vibrations caused by rock formation impacts, reducing fatigue and wear on the frame and mast, thereby extending the machine's service life. 3. Independent four-point hydraulic leveling: Enables precise leveling on uneven or sloped terrain, effectively ensuring drilling verticality and minimizing hole deviation in deep-hole operations. 4. Real-time pressure monitoring system: Detects pressure anomalies to rapidly anticipate risks such as stuck tools or cuttings blockages, facilitating timely intervention and reducing the risk of drill string entrapment. 5. Versatile expansion interfaces: Supports the addition of dust suppression units and foam injection systems; these help mitigate bit clogging in clay and mudstone formations, broadening the range of compatible geological conditions.
