Square New-Type Spiral Drill Pipe

The Square New-Type Spiral Drill Pipe is a specialized device designed for directional horizontal drilling within coal mine tunnels. Its features include:

• Structural Design: The drill pipe has a square-shaped structure, which, compared to the traditional triangular design, more effectively agitates the borehole wall, aiding in the rapid removal of coal slag.

• Connection Method: Both ends of the drill rod feature threaded connectors (male and female), which possess high resistance to bending, twisting, and pulling forces, along with good sealing properties, facilitating quick connections between two drill pipes.

• Spiral Grooves: The outer wall of the drill pipe includes spiral grooves. These not only help reduce resistance during drilling and retraction but also, in cases of stuck or buried drills, the edges of the spiral grooves can crush coal chunks, assisting in powder discharge and effectively resolving issues of stuck drills.

• Manufacturing Process: Utilizing an overall milling process enhances the wear resistance and overall strength of the drill pipe. The male connector, female connector, and pipe body are joined through friction welding, ensuring robustness and stability at the connection points.

• Application Range: Suitable for directional drilling of long-hole layers underground in coal mines, it can also be used in drilling operations in soft coal seams and similar rock formations where water flushing and slag removal are less effective. It is ideal for deep hole exploration, gas emission holes, water probing holes, anti-outburst holes, and interlayer holes. When used in conjunction with display equipment at the hole mouth, real-time monitoring of drilling trajectory data is possible, allowing operators to adjust the drilling direction based on the data, achieving the goal of directional drilling.
