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-4500D directional drill has an ultra-narrow body and is suitable for the construction of directional boreholes in mine advanced exploration, small and medium-sized roadway sections, crossheading boreholes, driving faces, across conveyor belts in the haulage roadway, and construction sites with near-horizontal directional long borehole operations in narrow spaces. It is used 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 spindle inclination of the product is -90° to +90°, and the azimuth angle is 0 - 360°. The chassis anchor cylinder can be rotated and adjusted to increase the support stability, making it easy and flexible to use.
