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-17000D/15000D/12000D/10000D drilling rigs have high torque and a reasonable speed range, and can also meet the requirements of small-diameter diamond core drilling, large-diameter carbide alloy core drilling, and various engineering drilling. They adopt patented technology cylinders, with a short overall machine length, a large cylinder stroke, and no idle space behind the power head. The cylinder can achieve continuous drilling of 1.2 meters in one feed, eliminating the need for secondary feeding, reducing the number of rod reversals, and improving productivity.
