Difference between Top Hammer vs Down the Hole Drilling - Drill Tech International

There are two types of drilling approaches used in industrial applications. Two common methods, the Top Hammer vs Down the Hole drilling methods, perform similar functions but in different ways. The primary difference between the top hammer and down-the-hole drilling methods is where the hammer is attached.

The hammer in the industrial equipment makes contact with the bit during the Down the Hole drilling method. The top hammer drilling method’s activity is concentrated at the very top of the drill string. The activity occurs separately from the bore.

Top Drilling

With the Top Drilling Method, the piston will increase to the ideal rate. Once the goal velocity has been reached, the striking part of the process begins and disturbs the particles. Once it has struck the surface, the particles disseminated are transmitted throughout the area.

As this is done repeatedly, the stress wave triggers a vibration throughout the rod based on the angling of the drilling activity. The stress waves created are influenced by the piston and drill string. Different geometric configurations shape the stress waves, determining the outcome of the drilling area.

Down the Hole drilling

During the Drill-Down the Hole method, the hammer doesn’t concentrate its efforts around the circumference. Instead, the process involves focusing the drill down the actual hole. The hammers strike the surface directly during the drilling process. Often chosen because it is the more accurate of the two approaches, it is able to maintain a consistent drilling rate.

Main Difference between Top Hammer vs Down the Hole Drilling 

Powered by pressurized air, down-the-hole drilling is a more efficient approach. The rate of this method is much slower. As the depth increases, the performance degrades. The Top Hammer Drilling relies on hydraulic energy, so its performance remains consistent regardless of the depth.

The downside is the top hammer drill requires frequent parts replacement over time because the stress applied rapidly increases wear and tear.

DTH drills are mechanically superior from an efficiency standpoint when compared to the top drilling counterpart. The Top Hammer Drilling approach achieves a consistent performance, making it the perfect choice for productive drilling at extremely low levels.

In determining whether or not one drilling method makes sense over another method, you can prioritize your goals. If consistency is the primary objective, then the hydraulic-powered top hammer is better suited. If you are looking for a more efficient experience, then the down-the-hole drilling equipment is probably a better fit.

Top Hammer Drills tend to have a longer service life when compared to their Down the Hole drilling counterparts. If accuracy is a focus, then the down-the-hole drilling technologies are the best fit. Both styles are well-suited for soft and medium rock. For use in hard work drilling, the Top Hammer Drills will provide the best experience.

What is Top Hammer Drilling - Drill Tech International

Top Hammer Drilling  Introduction

Drill Tech International of Top Hammer Drilling tools refer to those drilling rods which are used in construction, mining, or quarrying rock for drilling holes. These machines create a percussive force on the drill tubes or rods which is transmitted to the drill bit. The constant striking to the drill and its rotation speed enables the machine to drill holes into the hard rocks. Top hammer drilling combines with the drill and blast method, which makes the whole excavation process very efficient.

Key Drivers of the Global Top Hammer Drilling Tools:

Increasing demand for Top Hammer Drilling due to its size, availability, and low cost of drilling rigs is a driving force that helps to boost the growth of the top hammer drilling tools market globally. Drilltech International of Top hammer drilling tools are ideal for mining and underground operations; it can be taken to challenging locations, and drilling contractors make available machines at short notice as well. Top hammer drill rods are fast to set up and cost effective as compared to DTH which is also known as rotary drilling machine. Rising demand for top hammer drilling tools are because they are more suitable for narrow and short boreholes as they have a big impact on ground conditions. Top hammer method is preferred in tunnel forepoling, where ground condition is weak.

Factors Restraining the Global Top Hammer Drilling Tools:

As the top hammer drilling process moves down toward the end of the larger holes, its speed and efficiency is significantly impacted. Also, such processes result in large scale energy loss. These factors might hinder the demand for top hammer drilling tools as compared to down the hole drilling, which is more advantageous.

What is Top Hammer Drilling Method - Drilltech International

 Versatile and flexible, top hammer drilling is used by various industries all over the world.The rigs can be taken to challenging job locations, drilling contractors usually have machines available with short notice, and they tend to be cheaper than DTH or rotary drilling rigs.

"On the drilling consumable side, Top Hammer Drilling Method string is also cost-efficient, fast to set up and, with a wide range of available bit designs, top hammer bits can always be optimised for the ground conditions."

The advantages and possibilities of Top Hammer Drilling Method do, however, not just mean a broad range of possible applications, but also an equally broad range of clients and demands. Increased automation, longer bit durability and improved efficiency are among the requirements that need to be met by developers.

Ideal for Mining and Underground Operations

Ideal for drilling narrow and short boreholes (down to 1in wide and up to 40m in length) in hard rock, Top Hammer Drilling Method are primarily used in mining, construction, and for quarrying of rock material.

"Top Hammer drilling should be the default choice for all holes with a width between 1-1/2 - 4in and a depth of up to around 30m. Ground conditions do not impact so much on the choice of drilling methodology, but it obviously has a great impact on the tool selection. An exception to this is speciality applications like tunnel forepoling, where weak ground conditions mean that forepoling is necessary - which in turn automatically calls for top hammer methodology.

Specifically, the Top Hammer Drilling Method is widely preferred and used in underground mining operations because of the possibility of using water to flush out cuttings. Unlike other technologies, which flush with air, this improves the underground work environment by minimising the impact of drilling dust in the air.

On top of this, top hammer drilling allows for a larger number of smaller holes enabling more accurate and controlled blasting, something which is usually highly critical in underground operations.

The challenges and limitations of the Top Hammer Drilling Method

While advantageous in many situations, the top hammer method also has its limitations and drawbacks. One of the biggest challenges is the fact that as the drill string loses percussion energy towards the bit, longer rods will lead to a larger energy loss and less efficiency. 

Additionally, the repeated shock waves from the hydraulic hammer on couplings and rods of top drifter drill strings create continuous wear on components, meaning that top hammer drills usually require more consumables in the long run. This also goes for drill bits which, with traditional bits, may need to be changed or sharpened several times during a work session. The requirement for manually operated replacements or upkeep, in turn, works against one of the strongest demands within the industry, especially in underground drilling, namely the demand for greater automation.

New solutions and old skills

One of the requests most often voiced by drill operators is for automated and remote-controlled drilling machines capable of drilling an entire work session before being removed for the blasting operation. But while control systems might theoretically enable this, new solutions are necessary for consumables to practically allow it. flexible and fast to set up top hammer drills are ideal for narrow and short boreholes in hard rockFlexible and fast to set up, top hammer drills are ideal for narrow and short boreholes in hard rock.
