The crawler - mounted full - hydraulic directional drill for coal mines is mainly used for the construction of various engineering directional boreholes in coal mines, such as gas drainage, grouting for fire prevention and extinguishing, coal seam water injection, outburst prevention and pressure relief, water disaster control, and geological exploration. It is applicable to various coal seams and rock strata with a rock solidity coefficient f < 10. The drill can move independently and turn in place. It requires that the height of the roadway or drilling site is greater than 3m, the width is greater than 4.5m, and the cross - section is greater than 12m. It is also used for small - diameter diamond drilling in the exploration of metal and non - metal solid deposits, as well as for engineering geological surveys in civil construction, highways, railways, bridges, dams, national defense construction, and for engineering drilling in the exploration of hydrological oil and gas fields and dam grouting. The main supporting products of this drill include down - hole motors, mining MWD (measurement while drilling) devices, directional drill pipes, etc.

The ZYL-8500D(D)/7000D(D)/6000D(D) crawler-mounted full- hydraulic directional drills are commonly used for the construction of directional boreholes in roadway  They are mainly applied in aspects such as gas drainage, grouting for fire prevention and extinguishing, coal seam water injection, determination of coal seam thickness, outburst prevention and pressure relief, and geological exploration. The drill adopts a new all-round frame structure, integrating horizontal azimuth rotation, vertical lifting, inclination adjustment, and longitudinal and transverse anchoring. The inclination adjustment range is -30° to +90°, and the azimuth angle adjustment range is 0 - 360°, enabling quick adjustment of the opening height and inclination.
