ZYL-7000D,ZYL-6000D Crawler-mounted Full-hydraulic Directional Drills for Coal Mines

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-7000D/6000D is a new type of directional drill suitable for complex geological environments. It features a small size, high torque, high hole formation rate, and strong ability to handle downhole accidents. It is an integrated drill that combines the drill and the pump truck into one unit, with a compact structure and a wide range of applications. Its pitching angle can reach ±15°, the feed stroke is 1 meter, and the feed and pull-out force is 250 kN.
