(3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
Down-the-Hole Hammer Drilling An Innovative Approach in Mining and Construction
Jaw plates are commonly made from manganese steel, an alloy that boasts high wear resistance and toughness. Manganese steel typically contains between 11% to 14% manganese, which contributes to its unique and advantageous properties. The addition of manganese enhances the alloy's hardenability, allowing it to become exceptionally hard when subjected to heavy impacts. This characteristic makes manganese steel an ideal choice for high-stress applications, such as crushing abrasive materials in mining.
2. Road Work Ideal for applications such as road repair and maintenance, where heavy equipment is needed.
Conclusion
Advantages of DTH Hammer Drilling
1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.
2. Marine Construction When constructing offshore platforms, bridges, or wind farms, the stability of foundations is paramount. Hammer drilling provides a reliable method to secure pilings and conduct deep foundation work, ensuring that structures can withstand harsh marine conditions.
