Products Description
LEANOMS
The DTH Hammer DHD350 is a specific model of Down-the-Hole (DTH) hammer used in drilling applications. DTH hammers are pneumatic tools that are commonly employed in mining, construction, geothermal drilling, and other industries for drilling holes in rock and hard formations.
failure analysis
LEANOMS
The fracture location of the DTH Bit head often occurs at the diameter reduction area at the upper end of the DTH Bit head spline.
Common causes of DTH Bit head breakage are:
(1) The DTH Bit head itself is of poor quality,
Stress concentration, fatigue resistance, and shear strength are low.
(2) Excessive drilling pressure causes drilling tools to bend and vibrate.
Or the uneven softness and hardness of the ground may cause the DTH Bit head to work unevenly.
The torque on the DTH Bit head changes continuously at high frequency,
Under the action of multiple alternating impact forces and alternating shear stresses
The DTH Bit head breaks due to fatigue damage.
Preventive and treatment measures
(1) Choose good quality manufacturers,
To reduce the occurrence of accidents in the hole due to the quality of the DTH Bit Head.
Strictly inspect the quality of the DTH Bit Head to prevent damaged DTH Bit Head from entering the well.
(2) Entering the loose and dissolved fissure zone,
For fractured zones and unevenly hard and soft formations, adjust drilling parameters in advance.
(3) When the formation conditions are unknown, drill with a small drilling weight first.
Then slowly pressurize to make drilling even and stable. Avoid drilling with high drilling pressure and high speed.
(4) When drilling into softer rock formations, the drilling pressure should be reduced. To prevent the carbide teeth from digging into the rock formation too deeply, as a result, the torque on the DTH Bit Head increases instantly.
Application
LEANOMS
The DTH Hammer DHD350 is typically used in the following types of countries and regions, which often have specific geological conditions and mining needs suitable for this type of drilling tool:
Mineral-rich countries: Those countries and regions with rich mineral resources, such as Australia, Canada, South Africa, Chile, etc., usually use DTH Hammer DHD350. This is because mine exploration and mining in these places require drilling in hard rock, and the performance of the DHD350 is suitable for this purpose.
Areas with rapid development of construction and infrastructure: Some countries and regions with rapid economic development, such as China, India, Brazil, etc., often need to use DTH Hammer DHD350 in infrastructure construction and construction projects. This is because they can be used to punch holes to support construction projects, bridge construction, road construction, etc.
Geothermal Energy Industry Countries: The geothermal energy industry often requires drilling deep wells to harness thermal energy resources underground. Countries with rich geothermal resources, such as Iceland and the United States, may use the DTH Hammer DHD350 to drill geothermal wells.
Water well drilling countries: Some countries and regions, especially those that are short of water or need water resources for agriculture and residents, may use the DTH Hammer DHD350 to drill wells to obtain underground water sources.
Mine Exploration Countries: Those countries with large-scale mine exploration activities usually use the DHD350 DTH Hammer to detect underground mineral deposits. These countries may include Canada, Australia, South Africa, etc.
The DTH Hammer DHD350 is very common in countries and regions where this type of drilling is required due to its performance suitable for drilling in hard rock formations. The main reason for choosing the DHD350 hammer is its ability to provide efficient and reliable drilling performance in challenging geological conditions, helping to meet project needs in different fields.
