Using DTH hammers for drilling has several advantages, including efficient drilling in hard rock formations. Compared to other drilling methods, DTH hammers can achieve greater depths when drilling in hard rock. This is because DTH drilling is performed using compressed air and a rotary percussion cutting action, making it more efficient than top hammer drilling. DTH drilling is one of the three methods of rock drilling, along with rotary drilling and top hammer drilling. DTH hammers are particularly useful for drilling in hard rock formations with a hardness over 200Mpa. Thus, using DTH hammers can lead to more efficient and effective drilling in challenging geological conditions.
Another advantage of using DTH hammers is the increased penetration rate. A study by Cao et al. demonstrated that the use of a pneumatic DTH hammer in drilling through brittle and hard rock formations can significantly increase the penetration rate. Additionally, a study reported that the aggressive cutting structure of DTH hammers, in combination with efficient hammer design, can deliver a superior rate of penetration. This increased penetration rate leads to faster drilling and reduced downtime, ultimately resulting in cost savings for drilling operations.
Using DTH hammers can also reduce downtime and maintenance costs. DTH hammers have a simple and reliable inner structure, making maintenance easy and minimizing downtime. Furthermore, DTH hammers have lower oil consumption compared to other drilling methods, contributing to cost-effectiveness in drilling operations. A study by Xtega reported a reduction in the cost of drilling function by 7.5% when using DTH hammers. Therefore, using DTH hammers can lead to improved drilling performance, reduced downtime, and cost savings in drilling operations.
