Product Description ： The YGQZ-800 is a portable, deep-hole Down-the-Hole (DTH) drilling rig capable of reaching depths of up to 800 meters and drilling holes with diameters ranging from 127 mm to 325 mm. Built on a heavy-duty crawler chassis and powered by a high-output hydraulic system, the rig utilizes an external air compressor to supply high-pressure air that drives the DTH hammer to crush rock, while simultaneously using airflow to clear cuttings. Optimized for formations such as deep limestone, granite, and fractured bedrock, it is suitable for projects including deep drinking water wells, industrial water supply wells, hydrogeological exploration holes, and mine dewatering boreholes.
Product Features： 1. Robust capability for deep-hole drilling in hard rock; the percussive drilling method is optimized for hard bedrock at depths of 800 meters, significantly shortening construction timelines compared to mud-based drilling rigs. 2. Dry air-based cuttings removal eliminates the need for large water supplies; this removes the requirement for mud pits at water-scarce sites—such as deserts or mountainous areas—thereby reducing investment in auxiliary infrastructure. 3. The heavy-duty chassis ensures high stability and vibration resistance during continuous deep-hole operations, effectively minimizing drill rod deviation, improving verticality, and guaranteeing well quality. 4. Automated drill rod handling reduces the physical strain of manual high-altitude operations; a centralized control console and integrated safety limit protections enhance operational safety during deep-well construction. 5. Versatile application: by simply changing the drilling tools, the equipment can be used for water wells, geological monitoring holes, and mine dewatering holes, allowing a single machine to handle a wide range of deep-well drilling projects.
